Description

Circuit breaker interlocks for use on outdoor poles

technical field

The utility model relates to a circuit breaker interlocking device, in particular to a circuit breaker interlocking device used on an outdoor column.

Background technique

The high-voltage switch on the outdoor pole is composed of a vacuum circuit breaker and an isolating switch. Since the isolating switch does not have the ability to open and close load current or short-circuit current, when the circuit breaker is closed, the isolating switch should be prohibited from opening. The structure in the prior art is relatively complicated, and the operation flexibility is poor.

Contents of the invention

The utility model mainly solves the deficiencies in the prior art, and provides a circuit breaker interlocking device on an outdoor column, which is reliable in locking, easy to install, and suitable for the interlocking of a high-voltage vacuum circuit breaker and a disconnector on an outdoor column. .

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

A circuit breaker interlocking device used on an outdoor column, including a circuit breaker, and also includes a isolating switch shaft fixing plate, an interlocking connecting rod, a circuit breaker closing and opening indicating shaft, and an opening and closing output flap. The isolating switch The shaft fixing plate is fixed on the outer wall of the circuit breaker. The said isolating switch shaft fixing plate is provided with a stop pin guide sleeve, and the said stop pin guide sleeve is provided with an interlock stop pin. An interlock mechanism shaft sleeve is provided, and the interlock mechanism shaft sleeve is provided with an interlock stop rod that is movable in contact with the interlock stop pin, and one end of the interlock link is fixed to the interlock stop pin , the other end of the interlocking connecting rod is provided with an opening and closing output turning plate, and the circuit breaker closing and closing indicating shaft is arranged in the opening and closing output turning plate, and the bottom of the circuit breaker closing and closing indicating shaft It is fixed with the circuit breaker, and an operation indicator rod is provided on the circuit breaker closing and opening indicating shaft, and the circuit breaker closing and opening indicating shaft rotates with the rotation of the operating indicating rod, and the opening and closing output flap follows The closing and opening indicating shaft of the circuit breaker rotates to drive the interlocking connecting rod to translate to the left, and the interlocking pin moves to the left along with the displacement of the interlocking connecting rod.

As a preference, the interlock pin and the interlock connecting rod, and between the interlock connecting rod and the opening and closing output flap are rotatably connected by fixed pins, and the bottom of the circuit breaker closing and opening indicating shaft passes through the fixing seat Fixed with circuit breaker.

Preferably, the isolating switch shaft fixing plate is distributed in a knuckle shape.

When the circuit breaker is closed and the isolating switch is in the open state, during the closing process of the circuit breaker, the closing and opening indicator shaft of the circuit breaker rotates to drive the opening and closing output flap to rotate, thereby driving the interlocking connecting rod to move to the right, thereby preventing the interlocking mechanism shaft sleeve Turn to the closing direction of the isolating switch so that the isolating switch cannot be closed at this time. Satisfies the safety requirement that the disconnector cannot be closed when the circuit breaker is closed when the power is on.

The circuit breaker is closed and the isolating switch is in the closed state. At this time, the interlocking link prevents the shaft sleeve of the interlocking mechanism from rotating in the direction of opening the isolating switch, so that the isolating switch cannot be opened at this time. It meets the safety requirements that the disconnector cannot be opened when the circuit breaker is closed when the power is on.

Therefore, the utility model provides an interlocking device for circuit breakers on outdoor poles, which has excellent operability, good linkage performance, and is easy to use.
