Dear technically competent accomplices!

Who is smart, please calculate what is the minimum core diameter for powering one 250-watt DRV lamp.

It is necessary to take a lamp with a wire on a trip-accordingly, the smaller the cross-section, the longer the wire can be taken (weight is strictly limited).

How to calculate it. But in fact, in my opinion, the usual two-core electrical cord in double insulation, which is connected to the outlet of most household appliances, is quite enough (small power)

.
Eg: SHVP 2x0. 5 it'll do just fine.

Yeah, still counting....here nefig to do that! Take a cross-section of 0.75-1.5 sq. mm

What's the point of spending the night? There is no need (especially when you select the cross-section several times a day). I would not take a wire thicker than 0.75 sq. mm for such purposes. 0.5 is a little afraid, but you need to try, the current is not particularly high, the starting mode is not very tight, it will not have time to overheat. The main thing is not to cling to the lamp far from the throttle.

There is no throttle. As I wrote above, I take the DRV with me, not the DRL.

0.5 sq. m.mm is normal: 500 w. incandescent it pulls only in the way. These tolerances are always overestimated, so as not to be chemical (reinsurance is banal). A friend of mine in the garage DRL 250 was connected for a very long time and burns for hours: there is nothing to be afraid of. And here in general DRV (bezdrosselnaya).

In general, when choosing a wire for carrying, I would never take a cross-section of less than 1 square. mm, and preferably 1.5.Regardless of the load. The fact is that the mechanical characteristics of the wire are very important here. The larger the cross-section, the more reliable the insulation there is, the stronger the cord at break. yes, and el. characteristics too-according to the tables, yes, 0.5 kV mm is also suitable, but with a length of 10 meters and given that modern copper for wires is more like iron, it will no longer be a wire but a resistor ))))

By the way, in the DRV lamp, a tungsten filament is used instead of the throttle, that is, it is actually an incandescent lamp+DRL - which is much worse than DRL with a throttle in current consumption

05.08.2012 21:52, Zlopastnyi Brandashmyg

And one more question: does anyone have any experience of putting DRL/DRV lamps in the luggage compartment of an airplane and receiving them safely on arrival?

Passed and received safely. You need a hard case so that the lamp is not crushed, and a tight fixation so that it does not hang out in the case. I used a hard plastic container, and the lamp was tightly wrapped with cotton wool.

By the way, for those who often catch on non-split lamps, phosphor, which actually burns with white fire in savings banks and drv, is subject to burnout and loss of light-energy spectral properties, the first notification of loss is when the eyes stop getting tired when they are near the screen for a long time, UV savings according to the recommendations of experts lose in the first year of operation-50%.

Why would it be worse? In this case, we have a purely reactive load on the network, which, in particular, greatly simplifies the life of the generator. And the current through the lamp is still the same (otherwise the brightness drops), namely, the current meter measures.

06.08.2012 12:13, alex017

DRV has a return of about 20lm / w. DRL - ok 60lm / w.
Hierophis don't scare people, dear. I also love reinsurance, BUT when it comes to aircraft and luggage, other factors are important, namely weight and dimensions and a minimum margin up to zero.

recently, some gravediggers arrive black, I took 3 things, but maybe someone else needs it?

These most likely (they really like to go to the light). If so, then the beetle is quite common.

yes yes, and it smells like some kind of medicine, but I can't understand kakim

Gravediggers and scavengers raise their bellies and spray a strong-smelling secret when attempting violent acts,while there are no bacteria.They are not carriers of all the infection, max matters.size, I do not catch small imagos, from 3.0 cm, and large males with curved legs are fundamental beetles, IMHO.

Gentlemen be lenient)
There is an ESL 65V lamp at the output of 325 V, the Kelvin temperature is 6400K, what can I catch in the south of the Chernihiv region?
And what else do you do with the insects you've already caught?

Lamer in this matter, but learning)

We eat, of course, insects! Where else are they)))
Caught on your eslku the same as on the drl. Maybe a smaller amount. wait longer, and there are fewer species.
And for the future: there are no equivalents! ESL is just an ugly shaped (curved) linear fluorescent lamp with a corresponding efficiency of up to 80lm / w.

Purely theoretically. There is such a lamp:
http://www.mir-elektriki.ru/index.php?productID=4623
The description says:
>>"Due to the built-in ignition electrodes, no additional ignition devices are required."
Can this lamp be used in a split version and without a special throttle?

31.08.2012 4:51, alex017

And can an incandescent lamp be used in a split version?))

31.08.2012 5:04, Bianor

There is also such a catalog of lamps:
http://www.1000watt.ru/catalog.html?category=8&page=2
And a whole section - "traps for insects"

alex017
The spiral will burn up instantly.

The usual DRL-250 lamp. Whether it can be used in a split version without a throttle has already been discussed many times in the topic.

31.08.2012 8:36, Bianor

okoem, there is something added in the description. And there is a lamp with external ignition, there is an internal one. Actually, the question was about this particular model, and not about the drl as a whole. If all this is irrelevant information, or I looked in the wrong direction, or it's just a lie and profanity, then one word in the answer would be enough for me: "no", without a half-page discussion, without unnecessary humor and hints.
Something like that.

Based on the description ("Due to the presence of built-in ignition electrodes, no additional ignition devices are required."), it can be used without a throttle.
Based on the name , this is a regular DRL. Without a throttle, it won't light up stupidly.
Try it, the price of the experiment is 150 rubles in total, it's not so bad if it burns.

31.08.2012 8:48, Bianor

Bad Den, if you try to start with a throttle - it will not light up, so you need to do it without it. An option?
However, given the price, you can try out both options...

31.08.2012 9:05, Egorus

DRL when switched on directly does not just burn out, but burns out instantly

31.08.2012 9:21, okoem

Based on the description ("Due to the presence of built-in ignition electrodes, no additional ignition devices are required."), it can be used without a throttle.

But nowhere does it say what can be used without ballast.
If there is no ballast, how can the current of the discharge mercury tube be limited?

31.08.2012 12:14, Alexandr Zhakov

Either the person who wrote the description wrote something wrong, or we misunderstand it. (I personally

)

DRL stupidly blymknet last time and will never light up again

Try it, the price of the experiment is 150 rubles in total, it's not so bad if it burns out.

Add money and buy a choke

, this is not an experiment, but the destruction of the lamp.

>>Add some money and buy a throttle

The throttle is available, but it is already podzadolbal...

31.08.2012 12:50, Alexandr Zhakov

This can only be done when you are wearing the throttle.
Alternative: DRV, if with a generator, tungsten spiral, if from the mains.
I apologize for the repetition, this has already been discussed this time.

31.08.2012 13:42, Bianor

My throttle is just not heavy - the usual nichrome spiral. But at the same time, firstly, a lot of material burns on the lamp, and secondly, the spiral often burns out. I tried to take it out of the lamp, it turns out even worse - the lamp without heating starts to shine at half strength and the question of fire safety arises.

31.08.2012 15:40, Alexandr Zhakov

Frankly speaking, I didn't understand the design of your light trap, where the DRL is, where the spiral is, and where the fire hazard is.

31.08.2012 15:55, Bianor

The mercury-quartz lamp itself is mounted between two ceramic tubes in which nichrome spiral chokes are enclosed. They heat themselves and heat the lamp. I tried to remove them from the case and place them separately on a metal grate - the lamp without heating began to shine twice as weak, I had to return it to its place. I'm pretty tired of all this construction and I want to build two sets of UV lights - a stationary one on the wall of the house (a regular throttle from a regular DRL will do here) and some kind of camping one-compact, similar to the current one, but not giving such heat.

31.08.2012 16:00, alex017

Why not try sd in combination with ll for UV sterilizers?

31.08.2012 16:31, Alexandr Zhakov

My opinion is that here the question is not in the heating of the mercury-quartz lamp (the temperature of the DRL bulb itself, during operation, is higher than that of ceramic tubes with a spiral inside), but in the wiring diagram of the elements.

31.08.2012 17:49, okoem

Yes, but more precisely - not in the scheme, but in the wrong selection of ballast. With a "weak" ballast, the lamp will quickly burn out, and if the opposite is true, it will not reach full power.

2 Bianor
If the lamp does not develop full power, it is necessary to unwind part of the nichrome.

I had the same nichrome in all cases - I just took out the tubes, put them on an iron grate and connected them to the system in the same order. And the lamp began to shine faintly. I checked it several times.
Has anyone tried how the lamps on the link that are "in insect traps" show themselves-BL350 / 368 (G5, G13, 2G11)?

Here you have all the same problems

Using spirals instead of a throttle is not rational. Put a capacitor and do not suffer, and who is richer-there is such an option

http://www.svets.ru/shop1007_0_0.html

however, unlike the capacitor, this garbage can burn at any time, or rather even so - it will definitely burn at any time ))))
