Problems solved by technology

Although this method takes up less space than method (1), it still takes up a lot of space because the overall moving distance is larger (the problem is more serious at 40.5KV level).
In addition, because it moves together with the circuit breaker and its operating mechanism, the weight is very heavy, the operation is complicated and the manufacturing cost is high

Embodiment Construction

[0016] Referring to Fig. 1 and Fig. 2; the working process of the circuit breaker is as follows: the operating mechanism rotates the main shaft (31) through the pull rod and the crank arm ((installed on the main shaft (31)), and makes the crank arm (27) through the insulating pull rod (28) ) rotates counterclockwise around the shaft, and finally pushes the movable contact of the arc extinguishing chamber to move upward through the joint screw (26) to close the circuit breaker. At the same time, when the main shaft (31) rotates clockwise, it pulls the opening spring (32) to extend, Energy storage. The operating mechanism continues to move after the switch is closed until the contact contacts, so that the contact compression spring on the insulating rod is compressed, so that the moving contact maintains a certain pressure. Finally, the operating mechanism is locked at the closing position. When the switch is opened, The operating mechanism is unlocked and released, the main shaf...

Abstract

The novel high voltage breaker-isolating switch combination device consists of arc distinguishing chamber, upper and lower isolating contacts, transmission mechanical, and insulating parts. Owing to that the isolating contacts and the breaker are combined together to form one new independent combined devie, the present invention has over 50% reduced volume and greatly lower cost compared with traditional separated isolating switch and breaker. In addition, the isolating contact is telescopic, rather than rotary, structure and this further reduces the occupied space.

Description

technical field [0001] The invention relates to the field of high-voltage electrical appliances, in particular to a novel high-voltage circuit breaker-isolating switch combined electrical appliance. Background technique [0002] There are two methods of matching circuit breakers and isolating switches that are widely used at present: [0003] (1) Install two independent isolating switches on both sides of the incoming and outgoing lines of the circuit breaker, and connect them with wires to form a power supply (power receiving) unit. This method is relatively simple, but takes up a lot of space, and is mostly used in 12KV level switch equipment. [0004] (2) Fix the isolated moving contact on the upper and lower outgoing lines of the circuit breaker, and the circuit breaker and its operating mechanism and the moving contact move back and forth at the same time to make it connect or disconnect with the isolated static contact. Although this method takes up less space than t...
