Conductive parts manufacturers: what is the difference between the fixed vacuum circuit breaker and the handcart type

Taizhou Tongren Electric Co., Ltd. was established in February 2008 and is located in Yanpan Industrial Zone, Qianjiang Town, Yuhuan City, Zhejiang Province. It is a private enterprise that produces and sells switches, electronic components, and electrical accessories. The company covers an area of 8,620 square meters and currently has more than 110 employees, including 4 technicians and 8 quality inspectors. Specializing in the production of electronic components and electrical accessories such as handcart-type conductive parts and fixed conductive parts, as a professional manufacturer of conductive parts, Tongren Electric tells you: What is the difference between the fixed vacuum circuit breaker and the handcart type:

Vacuum circuit breaker (English name: Vacuum circuit breaker), named after its arc extinguishing medium and the insulating medium in the contact gap after arc extinguishing are both high vacuum; it is small in size, light in weight, suitable for frequent operation and arc extinguishing The advantage of no overhaul is more popular in the distribution network. The vacuum circuit breaker is an indoor power distribution device in a 3~10kV, 50Hz three-phase AC system. It can be used as the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. For maintenance and frequent operation places, circuit breakers can be configured in center cabinets, double-layer cabinets, and fixed cabinets for control and protection of high-voltage electrical equipment.

1. Different operation methods

When the vacuum circuit breaker is moved out of the handcart type, it is equivalent to an isolation fracture in the stroke.

When the fixed vacuum circuit breaker is removed from operation, it usually needs to form a circuit with an isolating switch.

Two, the cabinet type is different

The handcart type of vacuum circuit breaker is usually KYN28 series.

The fixed cabinet type of vacuum circuit breaker is usually XGN series.

Three, the cost is different

The cost of the handcart type vacuum circuit breaker is higher than that of the fixed vacuum circuit breaker.

The structure of the vacuum circuit breaker: The vacuum circuit breaker is composed of a conductive circuit, an insulation system, a seal and a shell, and the overall structure is a three-phase common box type. Among them, the conductive loop is formed by the conductive rod of the incoming and outgoing wires, the insulating support for the incoming and outgoing wires, the conductive clip, the soft connection and the vacuum interrupter. The mechanism is electric energy storage, electric opening and closing, and manual function.

The working principle of the vacuum circuit breaker: The vacuum circuit breaker uses the high vacuum when the current flows through the zero point, the plasma rapidly diffuses to extinguish the arc, and completes the purpose of cutting off the current.

The fixed type is fixed on the shelf in the cabinet with screws. It is easy to install and cheaper than the handcart type. The handcart type is safe for maintenance.

The handcart type is that the switch can be pulled out of the cabinet, which is convenient for maintenance, and the installation is more troublesome than the fixed type, and the price is more expensive than the fixed type.
