Abstract
The utility model relates to the technical field of a high-voltage switch, in particular to an interlocking mechanism of an isolation switch and a circuit breaker. The interlocking mechanism comprises a circuit breaker, an isolation switch, an L-shaped turning arm, a connecting plate and the like, wherein an operation hole is arranged in the panel; the rear side of the operation hole is provided with a valve; an interlocking plate is provided with two long round holes that are arranged in the isolation switch, can move up and down and can be restrained crossly with the valve; a pulling spring is arranged on the valve; the other end of the pulling spring is fixed on the panel; a spring is fixed on the interlocking plate and is connected with the isolation switch; one end of the L-shaped turning arm and the interlocking plate are arranged in the isolation switch simultaneously by a pin; the other end of the L-shaped turning arm is connected with the turning arm on the main shaft in the circuit breaker by the connecting plate; in the utility model, the movement of the turning arm in the circuit breaker is converted into the upward motion of the L-shaped turning arm in the isolation switch by the connecting plate, thus further controlling the switch of the isolation switch valve; therefore, the interlocking mechanism has simple and convenient structure, has high reliability and is economical and safe.
Description
Technical field
The utility model relates to the high-voltage switch gear technical field, especially the interlocking device of isolating switch and circuit breaker.
Background technology
As everyone knows, high voltage switchgear is by " five anti-" requirement: when breaker open operation, isolating switch allows operation, when breaker closing, isolating switch can not be operated, for realizing above-mentioned requirements, what the interlocking of at present big multi-separation switch and circuit breaker adopted is non-mechanical structures design, therefore inevitably reflect complex structure, cumbersome, poor reliability be installed, troublesome poeration, and shortcoming such as expense is also high, and economy is relatively poor.
The utility model content
The utility model be to provide a kind of simple in structure, easy for installation, reliability is high, and the interlocking device of the isolating switch of economic security and circuit breaker.
The technical scheme that its technical problem that solves the utility model adopts is: the interlocking device of isolating switch and circuit breaker, it comprises circuit breaker, isolating switch, L shaped connecting lever, connecting plate etc., panel is provided with handle hole, the handle hole rear side is provided with valve, interlock plate is provided with two slotted holes, be installed in the isolating switch, can move up and down, with the valve corss-over constraint, valve is provided with extension spring, and the other end is fixed on the panel, is fixed with spring on the interlock plate and is connected in the isolating switch, L shaped connecting lever one end and interlock plate are installed in the isolating switch by pin simultaneously, and the other end links to each other by the connecting lever on the main shaft in connecting plate and the circuit breaker.
When breaker open operation, main shaft drives connecting lever and rotates, connecting lever drives L shaped connecting lever by connecting plate and moves upward, and interlock plate upwards lifts under the effect of spring, at this moment, valve can be opened with hand push, expose handle hole, isolating switch can be operated, and opens when openhanded, valve is closed under the reset response of extension spring automatically;
When breaker closing, the connecting lever on the main shaft rotates, and drives L shaped connecting lever by connecting plate and moves downward, thereby interlock plate is pressed down, and at this moment, the valve of isolating switch is blocked by interlock plate, can not open, and isolating switch can not be operated.
The beneficial effects of the utility model are: the utility model interlocking device, by the rotation of connecting plate with connecting lever in the circuit breaker, change into the upward motion of L shaped connecting lever in the isolating switch, and then the switch of control isolating switch valve, simple and convenient, reliability is high, and economic security.
