Problems solved by technology

The cover body is exposed to high temperature at high temperature, and usually the metal shell can be exposed to the sun at 70-80 degrees in summer. The square cover, especially the rectangular cover, has different linear expansion. Poor seal
[0005] In addition, due to the high degree of equipment centralization and closer coordination, the losses caused by failures are also greater
The Chinese patent (CN201410774905.4 switch knock indicator on the column) realizes the alarm operation after the fault causes knocking through a series of connecting rods and alarm devices, but this connecting rod structure, due to the need for multiple conductions, will , if the connecting rod itself is displaced under vibration, it may not be able to alarm, so its reliability is relatively low
Moreover, the space required for connecting rods is relatively large, the structure is very complicated, and it is difficult to install and produce.

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the utility model is described in detail.

[0030] Such as Figure 1-6As shown, it includes an outdoor vacuum circuit breaker 10 on the pole, an electromagnetic voltage transformer 20 fixed on the bracket 11 of the outdoor vacuum circuit breaker 10 on the pole, and a feeder terminal device 30 electrically connected to the electromagnetic voltage transformer 20. The post-mounted outdoor vacuum circuit breaker 10 includes a box body 12, a spring operating mechanism, and three sets of arc extinguishing assemblies 13 arranged in the box body 12. The two ends of the three sets of arc extinguishing assemblies 13 are respectively connected with exposed boxes Three incoming terminal posts 14 and three outgoing terminal posts 15 outside the body 12. The arc extinguishing assembly 13 includes an insulating box 131, a vacuum interrupter 132 arranged in the insulating box 131, and a vacuum interrupter connected to the vacuum interrupt...

Abstract

A high-safety primary and secondary fusion column switch comprises a column outdoor vacuum circuit breaker, an electromagnetic voltage transformer and a feeder terminal device, wherein the column outdoor vacuum circuit breaker comprises a box body, a spring operating mechanism, three groups of arc extinguishing assemblies arranged in the box body, a sealing structure capable of resisting stress invarious directions is arranged at the top of the box body, and a knock detection box capable of monitoring knock and alarming is fixed at the bottom side. The column switch has higher integration level and better safety performance.

Description

technical field [0001] The invention relates to an on-pole switch used in a power system, in particular to an on-pole switch with primary and secondary fusion. Background technique [0002] At present, State Grid aims to build "safety, reliability, integration and efficiency" as its technical goal, demand-oriented, and testing as a guarantee. For outdoor vacuum circuit breakers in the construction and transformation of distribution networks, the overall design is standardized, and the functional modules are independent. The idea of ​​flexible equipment interchange is to give priority to solving the problems of remote signal jitter in the construction of distribution automation, the compatibility and scalability of primary and secondary interfaces, and the new line loss collection function of the terminal. Set high-precision, wide-range voltage sensors and current sensors to meet the requirements of fault detection, measurement, calculation and other functions and calculation...
