Problems solved by technology

But when the circuit breaker opens and closes the circuit, the SF inside the equipment 6 Under the impact of high-voltage electricity, it is easy to produce toxic gases. If there is a defect in the product seal, these gases will penetrate into the atmosphere and the environment and cause harm to people and the ozone layer in the atmosphere. Therefore, research on non-polluting insulation technology has always been a An important topic in the field of high voltage transmission and distribution

specific Embodiment approach

[0010] The bushing (1) part adopts a composite insulating bushing, and a terminal is arranged on the top of each bushing, so that the whole electrical appliance can be connected with an external wire. An aluminum tube is used as a conductor inside each bushing, and the three bushings are all connected to a shell to form a bushing part. The interior is filled with dry nitrogen or other inert gas whose pressure reaches higher atmospheric pressure for insulation. The specific pressure is related to the voltage level of the main equipment, and the size of the conductor is mainly related to the size of the rated current; the shell of the busbar (2) part is made of cast aluminum alloy, the inner conductor is made of aluminum tube, and the inside is filled with dry nitrogen or other inert Insulation by gas; isolation-grounding switch (8) parts, copper-tungsten alloy is used for conductors in parts prone to arcing, and vacuum insulation is used inside; current transformer (3) parts us...

Abstract

The invention relates to an insulation mode for a metal closed combined electrical appliance of a high-voltage substation. A high-voltage sleeve, a current mutual inductor, a voltage mutual inductor, an isolation-earthing switch, a breaker and an operation mechanism are connected to form a sealed body through a bus; different parts are separated into different air chambers by using an isolation insulating basin; and different gases are filled into different air chambers or the air chambers keep a vacuum state. The breaker and an isolation switch part in the combined electrical appliance adopt vacuum insulation, and other parts adopt an insulation mode by combining nitrogen or other inert gases. Therefore, the insulation mode saves the production cost, reduces the product cost, and solves the problem that when SF6 gas insulating totally-closed combined electrical appliance is carried out product inspection and repair, the gas is leaked because of incomplete gas recovering or poor product sealing to pollute atmosphere.

Description

technical field [0001] The invention relates to an insulation method of a high-voltage combined electrical appliance, in particular to an insulation method of a metal-enclosed combined electrical appliance in a high-voltage substation. technical background [0002] With the continuous development of my country's power grid construction, higher requirements are put forward for the personnel safety, equipment environmental protection, reliable operation and economical aspects involved in the complete set of power transmission and transformation equipment. In recent years, with the continuous advancement of technology, in order to save land resources, there have been SF 6 Gas-insulated metal-enclosed combined electrical equipment, which is a combination of primary equipment other than transformers in a substation, including circuit breakers, bushings, isolating switches, grounding switches, current transformers, voltage transformers and other components, is enclosed in a ground...
