Abstract
A maintenance method for abnormally-high gas pressure of a spring energy storage type circuit breaker is characterized by comprising the following steps: a) detecting a pressure meter; b) detecting a pressure storage cylinder piston; c) detecting whether oil and gas are mixed; d) detecting a microswitch. The invention designs the detecting steps and the detecting method according to possible fault positions and fault possibilities; according to the maintenance method, the fault positions can be rapidly judged, faults can be eliminated pertinently, the running safety and the running stability of a system are guaranteed.
Description
Technical field
The present invention relates to spring energy-storage type circuit breaker gas pressure anomaly height repair method, belong to overhaul of line breaker technical field.
Background technology
Spring energy-storage type circuit breaker than the hydraulic structure of oil circuit breaker and electromagnetic structure more advanced, power supply capacity is little, action is fast, safeguard simple, there is insulating properties ideal, environmental suitability be strong, break performance good, lightweight, volume is little, current capacity is strong, advantage that arc extinguishing ability is good, but once break down, harmful effect will be produced to the operation of electric power system, the fail safe run in order to safeguards system and stability, for this reason, maintenance and service work must be carried out.
Summary of the invention
For achieving the above object, the present invention is realized by following technological means:
Spring energy-storage type circuit breaker gas pressure anomaly height repair method, is characterized in that: comprise the following steps:
A) detected pressures table;
B) storage pressure cylinder piston is detected;
C) whether air-fuel mixture is detected;
D) sensitive switch is detected.
Further:
Described spring energy-storage type circuit breaker gas pressure anomaly height repair method, is characterized in that: described step a) comprises, as Pressure gauge is malfunctioning, under manometer tube joint, sets up damping hole.
Described spring energy-storage type circuit breaker gas pressure anomaly height repair method, is characterized in that: described step b) comprise, as bad in storage pressure cylinder piston seal, repaired.
Described spring energy-storage type circuit breaker gas pressure anomaly height repair method, is characterized in that: described step c) comprise, after air-fuel mixture, after disintegration, change sealing ring.
Described spring energy-storage type circuit breaker gas pressure anomaly height repair method, it is characterized in that: described steps d) comprise, check the relative position of storage pressure cylinder piston rod, if piston rod is higher than the just stall of high pressure locking sensitive switch oil pump, belonging to oil pump stops sensitive switch contact not open, pressure of slightly draining the oil makes blackout, changes sensitive switch.
The invention has the beneficial effects as follows: overhaul according to the method, can failure judgement position fast, remove fault targetedly, the fail safe that safeguards system is run and stability.
