Description
Technical field:
The utility model relates to a kind of pneumatic mechanism for circuit breaker A.C. contactor fault Emergency Tool, is applicable to circuit breaker pneumatic controlling mechanism A.C. contactor fault, when motor cannot start suppress time emergency processing use.
Background technology:
Primary cut-out major part in electric power system adopts pneumatic operator, in the day-to-day operation of primary cut-out, due to the gas leakage of pneumatic operator pipeline junction, compressor non-return valve is blocked by dust, working cylinder piston weares and teares, pneumatic mechanism controls power supply or working power fault, cylinder trouble can not start the reason such as to be suppressed and often causes the pressure of pneumatic mechanism for circuit breaker to reduce, as found not in time, pneumatic mechanism pressure will cause circuit breaker cannot separating brake when being low to moderate locking value, if now break down, though protective device energy correct operation, but because circuit breaker can not separating brake, the accident causing protection overstep tripping to expand power failure range is occurred.Even if Timeliness coverage pneumatic mechanism pressure anomaly, need to carry out grid switching operation and switch operational mode during process, workload is comparatively large, consuming time longer.By analyzing a large amount of pneumatic mechanism for circuit breaker pressure anomaly event, find it is that energy storage motor to be suppressed in loop ac contactor coil and damaged and cause motor cannot start to suppress and cause in most cases.Therefore, development pneumatic mechanism for circuit breaker A.C. contactor fault Emergency Tool is the important guarantee processing circuit breaker pressure anomaly, correctly the excision system failure in time thus maintain system safety stable operation.
Utility model content:
Technical problem to be solved in the utility model is: provide a kind of pneumatic mechanism for circuit breaker A.C. contactor fault Emergency Tool, even continue to reduce in pressure anomaly and wait in emergency circumstances, the normal pressure value of forcing simultaneously conducting contact device three-phase contact that energy storage motor is started in time to suppress, recover pneumatic mechanism for circuit breaker, make circuit breaker can normal separating brake, guarantee power system safety and stability is run and has important practical significance.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of pneumatic mechanism for circuit breaker A.C. contactor fault Emergency Tool, described fault Emergency Tool comprises left operation panel and right operation panel, described left operation panel and right operation panel by the bolt rod aperture set by corner location, shank of bolt, be sleeved on Compress Spring on shank of bolt and rotating nut links together, the two ends of described Compress Spring are separately fixed on left operation panel and the madial wall corresponding to right operation panel; Described right operation panel madial wall is set side by side with on three copper bus sheets of " U " type, lateral wall and is fixedly installed column type gripping handle; The left operation panel corresponding with three " U " type copper bus sheets is provided with 6 bus sheets bore a hole; Described three " U " type copper bus sheets are corresponding with the position of the position that 6 bus sheets are bored a hole and pneumatic mechanism for circuit breaker A.C. contactor three-phase 6 contacts; The spacing clamp that can accurately locate is provided with in the top and bottom of described left operation panel.
Described left operation panel, right operation panel and column type gripping handle process by epoxy resin insulation material; On 6 end points of described three " U " type copper bus sheets and described left operation panel 6 bus sheets size, shape and the position of boring a hole match.
When using the utility model, after limiting card board set by left operation panel top and bottom is accurately located on the contactor, pressing column type gripping handle and then drive right operation panel and three copper bus sheets of " U " type along the axial direction of coil tension spring to left movement, 6 end points of three copper bus sheets of " U " type are connected with contactor three-phase six contact through after 6 bus sheets perforation, the conducting while of forcing contactor three-phase six contacts, energy storage motor are started in time suppress.When pneumatic mechanism for circuit breaker recovers normal pressure value, unclamp gripping handle, contactor three-phase contact disconnects, and motor stops suppressing.
The utility model can be communicated with the three-phase contact of contactor in time, and energy storage motor is started in time and suppresses, circuit breaker recovers normal breaking capacity temporarily, can reduce accident scope as far as possible, effectively reduces the workload of grid switching operation, greatly shortens the process abnormal time.
The utility model structure is simple, reasonable in design, even continue to reduce in pressure anomaly and wait in emergency circumstances, the normal pressure value of forcing simultaneously conducting contact device three-phase six contact that energy storage motor is started in time to suppress, recover pneumatic mechanism for circuit breaker, make circuit breaker can normal separating brake, guarantee power system safety and stability is run and has important practical significance.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of left operation panel in Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further explained and illustrate:
See Fig. 1 and Fig. 2, a kind of pneumatic mechanism for circuit breaker A.C. contactor fault Emergency Tool, comprise left operation panel 1 and right operation panel 4, left operation panel 1 and right operation panel 4 by the bolt rod aperture 10 set by corner location, shank of bolt 3, be sleeved on Compress Spring 2 on shank of bolt 3 and rotating nut 5 links together, the two ends of Compress Spring 2 are separately fixed on left operation panel 1 and the madial wall corresponding to right operation panel 4; Right operation panel 4 madial wall is set side by side with on three copper bus sheets 7 of " U " type, lateral wall and is fixedly installed column type gripping handle 6; The left operation panel 1 corresponding with three " U " type copper bus sheets 7 is provided with 6 bus sheets and bores a hole 8; Described three " U " type copper bus sheets 7 and 6 bus sheets bore a hole 8 position and the position of pneumatic mechanism for circuit breaker A.C. contactor three-phase 6 contacts corresponding; The spacing clamp 9 that can accurately locate is provided with in the top and bottom of described left operation panel 1.
