Abstract

The invention provides an installation method of a sulfur fluoride (SF6) gas breaker and relates to a novel method for installing the SF6 gas breaker. By the method, the SF6 breaker can be directly installed by using the former low-oil-content breaker base and the former cement rod base through the improvement on bases without dismantling the former low-oil-content breaker base. The method is high in working efficiency; the working safety can be guaranteed, the construction amount of civil engineering is reduced, the installation construction period is shortened, the power failure time is reduced and the working safety is guaranteed. The method adopts a frozen expansion resistance technology to avoid an inclined rod of the breaker base caused by temperature variation.

Description

technical field

[0001] The present invention relates to a kind of installation SF 6 A new method for gas circuit breakers, this method uses the original oil-less circuit breaker foundation, without dismantling the original oil-less circuit breaker foundation, through the transformation of the foundation, directly install SF 6 breaker. Background technique

[0002] With the continuous expansion of the power grid, the short-circuit capacity continues to increase. Many original SW 2 -66 type circuit breaker will be replaced by SF6 gas circuit breaker. Original oil-less breaker cement pole foundation, SF 6 The circuit breaker is based on steel, so the oil-less circuit breaker can only be hoisted after draining the oil, the original cement pole is removed, and SF is re-made in the original position 6 The foundation of the circuit breaker is then assembled and debugged for a new circuit breaker. In this way, there are problems of heavy civil work (10-15 days for foundation co...
