Overview
Description:

As a special accessory of the arrester, the disconnector is used in series with the arrester. Its purpose is to make the disconnector operate by using the power frequency short-circuit current when the arrester fails abnormally, so that the ground terminal of the disconnector can be disconnected automatically, and the arrester can be withdrawn from operation, so as to prevent the accident from further expanding. The fault arrester is also provided with the visibility of the disconnection mark, so that the maintenance personnel can find the fault point in time Line maintenance and replacement.

The separator can be divided into hot melt separator and hot explosion separator according to the use principle and performance. Using the short circuit current flowing through the failure arrester, the alloy fuse (or soldering tin) in the disconnector is fused to achieve the purpose of disconnection.

The thermal explosion type disconnector uses the short-circuit current in the failure arrester to generate the arc in the disconnector and detonate the thermal explosion element to achieve the purpose of disconnection.

The newest type of disconnector TLB-5, TLB-6 (or TLB-I, TLB-l1):

We have developed the TLB-5 type, TLB-6 type new type of disconnector, which has the characteristics of fast action, and can withstand the ability of the specified current shock and action load, each All the indicators meet the requirements of GB11032-2000 《AC gapless metal oxide arrester》 and IEC.C62 《Distribution remote lightning remover requirements》.

Features:

1. Wide range of operating current, combined with the characteristics of China's power grid, it can be detached under large work fault current (>50A), and can also be detached under small fault current (50mA).

2. The speed of disengagement can be matched with the reciprocating function of the circuit breaker. It is applicable not only to various voltage levels and various types of arresters, but also to different grounding systems (neutral grounded and ungrounded systems).

3. Strong impact resistance, no action under 2ms square wave and 4/10us high current impact.

4. The mechanical strength is high and the sealing performance is good before the explosion. The TLB-5 type can be matched with the lightning arrester below 35KV, and the TLB-6 type can be used with the 35-220KV lightning arrester.

5. Easy to install and replace, threaded external interface, and lightning arrester series connection is reliable and convenient, the disconnector is very convenient to replace the action.
