Abstract
An interlocking mechanism between a high-voltage circuitbreaker and an integrated isolating switch relates to a novel isolating switch interlocking mechanism and belongs to the field of high voltage switch operating mechanisms. A supporting operation shaft is arranged on a box body; a lock-out stop block is fixedly connected to the operation shaft; a lock-out supporting seat is fixedly connected outside the box body; the lock-out supporting seat and the lock-out stop block are arranged on the same outer side of the box body; a lock-out pin is arranged on the lock-out supporting seat in a penetrating manner; one end of the lock-out pin faces to the lock-out stop block, and the other is hinged with a lock-out transmission mechanism; one end of the lock-out transmission mechanism is hinged on a circuitbreaker position handle; the middle part of the lock-out transmission mechanism is hinged on the box body in a supporting manner; and the circuitbreaker position handle is hinged on the box body. When the interlocking mechanism is in a closing position, opening/closing of the integrated isolating switch can be carried out, so that misoperation can be avoided effectively, and the requirements of an extra-high voltage switch operating mechanism on security can be met.
Description
Technical field
The utility model relates to a kind of novel isolation switch mutual interlocking gear, belongs to high-voltage switch gear operating mechanism field.
Background technology
Primary cut-out is equipped with integrated isolating switch and has simple in structure; Characteristics such as volume is little, convenient for installation and maintenance; Receive numerous clients' approval; But in order to ensure having the anti-misoperation function between circuit breaker and the integrated disconnecting link: promptly circuit breaker is when closing position, and integrated isolation switch can not divide/closing operation; When circuit breaker during in the separating brake position, integrated isolation switch can divide/closing operation, and this just needs to have reliable mutual interlocking gear between circuit breaker and the integrated isolating switch, prevents misoperation, assurance equipment and personal security.
Summary of the invention
The purpose of the utility model provides a kind of safe, mutual interlocking gear between primary cut-out and the integrated isolation switch easily.
The utility model is the support operation axle on casing, on said operating axis, is fixedly connected the locking block, connects the locking supporting seat at the casing external fixation, and said locking supporting seat and said locking block are arranged in the same outside of casing; On said locking supporting seat, place a lockweight; One end of said lockweight is towards said locking block; The other end is hinged the locking transmission mechanism; The other end of said locking transmission mechanism is hinged and connected on the circuit breaker position handle, and the middle part of said locking transmission mechanism is hinged on said casing, and said circuit breaker position handle is hinged and connected on the said casing.
Lockweight can be free to slide front and back in the locking supporting seat, and the locking block is fixed on the operating axis of integrated isolation switch operating mechanism.During work; The locking supporting seat of the utility model is fixed on transfixion on the circuit breaker casing; Along with moving of circuit breaker position handle, the locking transmission mechanism is that the center rotates with the hinged point that is arranged on the casing, and lockweight is along with the rotation of locking transmission mechanism moves forward and backward; Because the locking block is fixed on the operating axis, the biconditional operation axle rotates together.When circuit breaker during in the separating brake position, the position handle moves downward, and drives the locking transmission mechanism and clockwise rotates; Drive lockweight simultaneously and slide backward, lockweight is separated, at this moment with the locking block; Operating axis can rotate, and can divide isolation switch/closing operation; When circuit breaker during at closing position, the position handle moves upward, and drives the locking transmission mechanism and rotates counterclockwise; Drive lockweight simultaneously to front slide, block the direction of motion of locking block, at this moment; Operating axis cannot rotate, and can not divide isolation switch/closing operation.
The utility model is when closing position, and branch/closing operation that can the locking integrating isolation switch is effectively avoided misoperation, can satisfy the demand of superhigh pressure switch operating mechanism to fail safe.
Description of drawings
Fig. 1 is the structural representation of the utility model at locked position of coupler.
Fig. 2 is the structural representation of the utility model in the off-position.
Embodiment
Like Fig. 1, shown in 2, the utility model is support operation axle 7 on casing 6, on operating axis 7, is fixedly connected locking block 5, goes back external fixation at casing 6 and connects locking supporting seat 4, and locking supporting seat 4 and locking block 5 are arranged in the same outside of casing 6.
On locking supporting seat 4, laterally place a lockweight 3, an end of lockweight 3 is towards locking block 5, and the other end is hinged locking transmission mechanism 1, and the other end of locking transmission mechanism 1 is hinged and connected on the circuit breaker position handle 2.The middle part of locking transmission mechanism 1 is hinged on casing 6 through bearing pin 8, and circuit breaker position handle 2 is hinged and connected on the casing 6 through bearing pin 9.
Integrated isolation switch is in when operation, and the anglec of rotation of its operating axis is about 70 °, and when isolation switch during at closing position, operating axis can only be rotated counterclockwise about 70 °, makes the isolation switch separating brake; When isolation switch during in the separating brake position, operating axis can only turn clockwise about 70 °, and isolation switch is closed a floodgate;
When circuit breaker during in the separating brake position; Circuit breaker position handle 2 moves downward, and drives locking transmission mechanism 1 and clockwise rotates, and drives lockweight 3 simultaneously and slides backward; Lockweight 3 is separated with locking block 5; At this moment, the operating axis 7 that connects integrated isolation switch can rotate, and can divide isolation switch/closing operation;
When circuit breaker during at closing position; Circuit breaker position handle 2 moves upward, and drive is closed transmission lock mechanism 1 and rotated counterclockwise, and drives lockweight 3 simultaneously to front slide; Block the direction of motion of locking block 5; At this moment, the operating axis 7 that connects integrated isolation switch cannot rotate, and can not divide/closing operation integrated isolation switch.
Claims (1)
