Automatic opening and closing high-voltage drop-out circuit breaker

Abstract

The invention relates to the field of power supply facilities, and particularly discloses an automatic opening and closing high-voltage drop-out circuit breaker. A transmission gear is driven by a motor, and the transmission gear and a poke rod respectively drive a transmission wheel to move left and right and rotate through a transmission part; the rotation of a screw rod enables a first pawl anda second pawl to move downwards, a second return spring is extruded, and the accumulated force is released after the first pawl is separated from the first pawl; a guide rod is rapidly upward, and alink pipe is driven to rotate through a guide column and a rotating rod to be closed; after an electromagnet is powered on, a telescopic rod on the electromagnet retracts, and a pull rod drives a sleeve to move downwards, so that a moving contact is separated from a static contact, the link pipe falls down to open. According to the invention, the forward and reverse rotation motor and the electromagnet are controlled manually or remotely, so that the opening and closing purpose is realized through a series of mechanical actions, inconvenience caused by over-high fuse and uneven terrain is avoided, and unsafe factors generated in rainy days are also avoided.

Description

technical field [0001] The invention relates to the field of power supply facilities, in particular to an automatic opening and closing high-voltage drop circuit breaker. Background technique [0002] In the transformers provided to users in my country, most of the power supply facilities use 10KV power supply lines, and a drop-out circuit breaker is installed on the transformer to make the input high-voltage line stop and transmit power. The device has a simple structure, low cost, and is easy to use and install. Some unsatisfactory places, such as the installation height, make it difficult for the staff to hold the link rod accurately in place when the power is cut off. At night and on cloudy and rainy days, it is difficult to complete the power outage and transmission, and there are also great safety hazards. There are piles of debris underneath, and the uneven terrain also brings a lot of trouble to the staff. During operation, sometimes due to the angle and the strengt...

Problems solved by technology

When operating, sometimes due to different angles and different strengths of force, multiple failures are caused, which prolongs the time for power failure and consumes a lot of physical strength.
