Description

Overhaul liftable turnover mechanism in handcart type breaker chassis

Technical field

The utility model relates to electric power overhaul equipment, and in particular to chassis of circuit breaker repair apparatus.

Background technique

Chassis of circuit breaker is breaker important component.Chassis and middle cabinet body Insulation Coordination, mechanical interlocking, safety It is reliable flexible.Chassis has isolation maintenance position and operating position, each position to be equipped with positioning device in cabinet, to guarantee to interlock Reliably, it is necessary to be operated by interlock error operation proof program.Chassis is all made of nut, screw rod shakes and promotes, exits, and operation is light Just.Once chassis is broken down, the normal operation of switching devices will cause influence, will cause certain line outage when serious.

To enhance power supply reliability, it is desirable that certain line outage times must not exceed 1 hour.This requires service personnel to exist Troubleshooting is finished within an hour, should accomplish that The faster the better.

Since breaker body weight is big, for maintenance safety, chassis maintenance must isolate it from breaker body Come, removes the bolt on pedestal using monkey wrench, but scene lacks the reliable lifting device for carrying out breaker body, So having to carry to overturn again from handcart by breaker body to overhaul, since breaker body weight usually exists 150kg or more at least needs 4 people to lift fortune, and is inconvenient to carry, also dangerous during carrying, and maintenance process is time-consuming It is inefficient.

By investigation, chassis of circuit breaker defect problem is generally divided into following four classes:

(1) microswitch node damages.The problem is mainly manifested in the S8 in chassis, the damage of S9 microswitch node or Wiring loosening contacts the reasons such as bad, and service personnel is needed to rush towards in-situ processing.

(2) interlocking bent plate fracture.If 10kV bus charges, the maloperation in middle position will lead to contact electric discharge up and down, make At personal injury, it is also desirable to which service personnel rushes towards in-situ processing.

(3) rod bending is interlocked.If after the multiple block action of blocking lever bending can not complex, will lead to breaker closing i.e. It can shake into or shake out, the serious requirement for violating " electric power safety working regulation ": be unable to on-load division disconnecting switch.Maloperation As a result will cause equipment electric discharge leads to injury to personnel, so service personnel is needed to immediately treat.

(4) turbine and worm damages.The abrasion or damage of turbine and worm can all make chassis that can not normally shake into shaking out, seriously Influence other normal blocking functions, it is also desirable to which service personnel immediately treats.

Moreover, four kinds of most common failures above-mentioned for chassis, probability of occurrence it is most be the damage of fine motion contact.Service personnel exists When handling microswitch node damage defect, lifts to throw to turn to dismantle on the spot using more people and overhaul, maintenance microswitch node damage When defect, it is necessary to breaker body is turned over and is turn 90 degrees, personnel's operation convenient to overhaul.Because handcart is because being limited under 90 degree of states Position bolt contacts to earth and can not shake.But during the treatment, repeatedly handcart to be shaken into shaking out, this results in service personnel Will overturning handcart repeatedly, this method easily occur breaker integrally fall touch, pole header contacts are squeezed to deformation, spring mechanism Crooked damage, service personnel's injury etc., to cause bigger destruction.
