Konka LCD TV users say that smoking, I am scared! Open the TV case and find the large capacitor drum package. After removing the replacement capacitor, there is no obvious short circuit in the circuit. The boot has no picture. In less than one minute, the image is gone. Quickly shut down and find that the lower part of the sound block under the capacitor is black. Measuring power supply 12V power supply and ground short circuit, blowing down this piece of STA333W, online shopping two 333BW shop owners said that the generation can be, after the good test 12V no short circuit, the boot has a picture silent! Have another piece, carefully, blow hard! The boot failure is still the same, the mountain is running out of water, what should I do? Suddenly I saw a headphone jack, connected to the headphones, there is a sound, and the volume can be adjusted, plus an amplifier, find an old audio amplifier board that does not read the card, remove the excess accessories, connect the power, input The ground wire, the boot picture sound is all coming, happy, installed to take away, the next day the customer brought it again, saying that the remote control shuts down and screams! Just test the machine, it is true, I am embarrassed to the customer, this time for you to get it right, take it in the afternoon! After the customer left, the 12V power supply is stepped down to 6.45V when the machine is turned off. How to fix the speaker? The only way is to cut off his power supply after shutting down. Just do it, find two-way thyristor, an old board, trial and error, and finally succeed, cut off the artery of the amplifier when shutting down! There is a circuit diagram of the thyristor. Repair is over!
The busbar protection box is made of radiation crosslinked polyolefin material with excellent physical, chemical and electrical properties.
It is the insulation treatment material where the busbar is connected.
It is also suitable for 1KV/10KV/35KV voltage grade, with "I", "T", "L" and other shapes of protection boxes. It is widely used in electronics, communication, machinery, manufacturing and other fields.
The specific gravity is small (only 0.9-0.95) and the window rate is high.
It seems that the purchase price is high and the actual use cost is low.
It can provide insulation and enhancement
for busbar connectors.And supply protection and insulation in switches and
substations.
Features:
1.Suitable for 1-35KV.
2.Radiation cross linking materials
(Polyolefin or EPDM rubber ).
3.Quick and easy installation.
4.Avoid short circuit and leakage.
5.Facilitate routine inspection and
maintenance.
6.Resistant to moisture and dust.
7.Meet RoHS Stand.
8.Customized.
