Problems solved by technology

As independent components, fuses and lightning arresters need to be assembled with their own supporting cross arms and other peripheral installation wires on the actual power supply and distribution installation lines. On the cross arm, the circuit design and installation operation are relatively cumbersome, and the incidence of circuit installation failures increases correspondingly due to messy wiring
Therefore, the existing independent power distribution equipment makes its installation and structure complex, resulting in many unsafe hidden dangers, which affect the normal operation of the power supply system

Embodiment Construction

[0013] According to attached figure 1 It can be seen that the present invention specifically relates to a drop-out high-voltage fuse, which includes an insulating support body 1 and an arc extinguishing tube 5 . The lower end of the arc extinguishing tube 5 is clamped by the clamping device, the support arm is fixed on the upper static contact 2, the lower static contact 3 is fixed on the clamping device, and the middle part of the insulating support body 1 is provided with a valve type lightning protection device. The valve-shaped lightning protection device includes a lightning protection valve body 8, a valve resistor 6 and a ground connection body 4. The valve resistors 6 are vertically arranged inside the insulating support body 1, and each valve resistor 6 is wrapped by an insulating layer 7, located at The upper valve resistor 6 communicates with the upper static contact 2, the valve resistor 6 is covered by the protective skirt 9 as a whole, the lightning protection va...

Abstract

The invention discloses a falling type high voltage fuse which comprises an insulation supporting body and an arc extinction tube. A supporting arm extending from an upper end of the insulation supporting body is hinged to the upper end of the arc extinction tube. The lower end of the insulation supporting body is clamped with the lower end of the arc extinction tube through a clamping device, and a valve type lightning arrester is arranged in the middle of the insulation supporting body. The falling type high voltage fuse combines the lightning arrester and a falling type alternating current high voltage fuse integrally, an installing structure of an electric transforming and distributing circuit is simplified, and the novel falling type high voltage fuse has a lightning protection effect required by short circuit, overloading and electric transforming and distributing circuits.

Description

technical field [0001] The invention relates to protection equipment for power supply and distribution lines and power transformers in a power system, in particular to a drop-type high-voltage fuse capable of lightning protection. Background technique [0002] The basic components of each power supply and distribution system on the power supply line include: high-voltage fuses, high-voltage isolating switches, power transformers, high-voltage circuit breakers, etc. It is an important protection device in the power supply network system to realize the short circuit and overload of the distribution line and the power transformer. There is also a valve-type arrester connection support for each phase line between the high voltage side and the ground line after the drop-out fuse. road to ensure that the power distribution equipment in the line can still operate safely during the thunderstorm season. As independent components, fuses and lightning arresters need to be assembled wi...
