Description
Technical Field
The utility model discloses circuit breaker technical field, concretely relates to outdoor vacuum circuit breaker vacuum insulation transmission.
Background
When a fault occurs in an electric power system, a high fault current corresponding to several tens of times of a rated current may flow due to a rapid reduction in load resistance. In order to prevent the spread of a fault area and the damage of other devices in the event of a power system accident, it is necessary to rapidly cut off the fault current by itself.
The circuit breaker used in such a case is a device for automatically shutting off a circuit by preventing damage caused by overload or short circuit in the circuit, and the reliability of the circuit breaker has a central influence on the reliability of the entire system.
In particular, among such circuit breakers, an air circuit breaker is used for a circuit having an ac voltage of 1000V or less and a dc voltage of 3000V or less, and the air circuit breaker is a circuit breaker for protecting a circuit in a short circuit or the like in which a slave circuit is opened or closed or a short circuit accident occurs.
The air circuit breaker is classified into a fixed type and a draw-out type having a structure capable of inserting or drawing out a breaker body into or from a case called a mount draw frame, which is different from the fixed type air circuit breaker. The draw-out type air circuit breaker is a basic form of the air circuit breaker because a case of the draw-out type air circuit breaker is provided with a device for performing an additional function of the circuit breaker so that the function of the air circuit breaker can be maximized.
In order to enable easy maintenance of the service circuit breaker, a draw-out type air circuit breaker is provided in which a circuit breaker body can be inserted into or withdrawn from a case. Therefore, a rotatable rotation shaft is provided on the bottom surface of the circuit breaker body so that the circuit breaker body can be inserted into or withdrawn from the case by a combination of a cam and a lever, wherein the cam is engaged with the rotation shaft and can be rotated on the inner surface of the circuit breaker body.
However, when the size of the air circuit breaker becomes large and the space in the distribution board is narrow, it is particularly troublesome to insert or withdraw the circuit breaker body into or from the case, and the probability of safety accidents occurring to the operator is high, and at the same time, the existing circuit breaker has a poor sealing effect, which easily causes the circuit breaker to be wet and reduces the service life.
