What is the full name of 10kv column vacuum switch watchdog-Shaanxi Taikai High Voltage Switch Manufacturing Co., Ltd. The full name of 10kv column vacuum switch watchdog is called "watchdog type intelligent vacuum circuit breaker" or "intelligent boundary vacuum circuit breaker".
A set of control unit (usually including: voltage transformer, CPU processor, communication module, etc.) is added to the vacuum circuit breaker, which has fault detection function, protection control function and communication function. It is installed on 10KV overhead line and can be realized Automatically remove single-phase ground faults and automatically isolate short-circuit faults between phases.

Extended information:
Boundary switch function
The single-phase ground fault is automatically cut off. When the single-phase ground fault occurs in the user branch line, the boundary circuit breaker will automatically open, and other branches of the substation and feeder users will not feel the fault. Automatically isolate the phase-to-phase short-circuit fault. When the phase-to-phase short-circuit fault occurs on the user branch line, the boundary circuit breaker will trip before the substation outlet protection switch to automatically isolate the faulty line.

JXHS series Junction Box advanced technology during production, stresses the details during design, implements design standard during processing, and has high consistence of product quality. It has various features such as strong damp proof, anti-corrosion and anti-electromagnetic capacities and high adjustment accuracy, and is suitable for various adverse environments. Its main advantages include:
The product uses own mold to make technologic design, the housing uses aluminum and silicon alloy and upper protrusion and lower sinking structure is used so as to ensure good sealing performance; protective grade reaches IP 68.
Main parts are imported, wiring bar is welded with precise anti-surge electronic components, which can prevent Load Cell damage caused by lightning and power grid surge voltage.
Whole device uses stainless steel grounding bolts to ensure reliable grounding during operation.
Assembly of junction box uses not-loose screws so as to avoid loss during load cell wring.
Wiring board uses combined screws for assembly, which are convenient for removal.
In order to ensure protective effect, force and diameter of tightening parts have introduction.
