Abstract
The utility model relates to the field of the isolating switch, in particular to an interlocking mechanism of an isolating switch and a circuit breaker, which comprises a main shaft, a crank, a baffle and a pin. The main shaft is arranged on the circuit breaker; the crank is arranged on the main shaft; the other end of the radial arm is connected with the baffle; the other end of the baffle is connected with a framework through the pin; and the framework is provided with an operating shaft. When the circuit switch is switched on, the main shaft rotates and drives the baffle to move through the crank, thereby covering the operating shaft and preventing the operation of the isolating switch; and when the circuit is switched off, the main shaft rotates and drives the baffle to move through the crank, thereby exposing the operating shaft and allowing the operation of the isolating switch. The utility model has the advantages of simple structure, convenient installation and reliable performance, and improves the production efficiency.
Description
Technical field
The utility model relates to the isolating switch field, and is concrete, relates to the interlocking device of a kind of isolating switch and circuit breaker.
Background technology
The present isolating switch and the interlocking device of circuit breaker generally all be by between the mechanical mechanism mutually constraint realize mechanism's interlocking, more complicated, parts are more, install also very loaded down with trivial detailsly, influence operating efficiency.
The utility model content
At the defective of present isolating switch and circuit breaker interlocking, the utility model provides the interlocking of a kind of isolating switch and circuit breaker, moves mutually by mechanism, cover or expose operating axis realize the interlocking, simple in structure, easy for installation, dependable performance has improved production efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: the interlocking device of a kind of isolating switch and circuit breaker, has main shaft, connecting lever, baffle plate, pin, main shaft is contained on the circuit breaker, connecting lever is installed on the main shaft, the connecting lever other end is connected with baffle plate, and the other end of baffle plate links to each other by pin with framework, and operating axis is installed on the framework.
The beneficial effects of the utility model are: the utility model provides the interlocking device of a kind of isolating switch and circuit breaker, breaker closing, and main shaft rotates, and drives the baffle plate motion by connecting lever, covers operating axis, and isolating switch just can not be operated; Breaker open operation, main shaft rotates, and drives the baffle plate motion by connecting lever, exposes operating axis, just can disconnecting switch operation.This interlocking device is simple in structure, and is easy for installation, and dependable performance has improved production efficiency.
