Problems solved by technology

As we all know, the molecular weight of nitrogen is very small, and the ability to adsorb charges is not strong.
Moreover, the heat capacity of nitrogen is relatively small compared with other gases, which can easily cause the temperature rise in the fully enclosed air box to rise rapidly.

Embodiment 1

[0039] Embodiment 1: The isolated upper contact and the grounding static contact are arranged symmetrically along the isolated lower contact, and the isolated upper contact and the grounding static contact are arranged in a figure-eight shape as a whole; the double-headed isolated movable knife plate One of the blades swings between the isolated upper contact and the isolated lower contact, and the other blade of the double-headed isolated movable blade swings between the isolated lower contact and the isolated lower contact. between the grounding static contacts. When the double-head isolating moving knife board rotates 60° clockwise, one of the two-head isolating moving knife plates is in contact with the lower contact of the isolation, and the other is in contact with the upper contact of the isolation to realize the closing position. In the current position, rotate 60°counterclockwise, one of the double-headed isolation moving blades will contact with the isolation lower c...

Embodiment 2

[0040] Embodiment 2: The isolated lower contact and the grounding static contact are arranged symmetrically along the isolated upper contact, the isolated upper contact is arranged vertically downward, and the isolated lower contact and the grounding static contact The head is arranged in a V-shape as a whole; one of the blades of the double-headed isolated movable blades swings and switches between the isolated upper contact and the isolated lower contact, and the other of the double-isolated movable blades A blade swings to switch between the isolated upper contact and the grounding static contact.

[0041] The isolated moving tool holder 3-1 is in clearance fit with the insulating upper main shaft 1-1 through a floating mechanism, the floating mechanism includes an insulating positioning sleeve and an elastic steel pin, on the insulating upper main shaft 1-1, along the insulating The axially upward sliding sleeve of the upper main shaft 1-1 is fitted with an insulating posi...

Abstract

The invention relates to novel environmental-protection-gas insulated totally-enclosed all-insulation ring network switch equipment. The equipment comprises a stainless steel welded sealed box body and an isolation switch component installed in the stainless steel welded sealed box body. A cavity in the stainless steel welded sealed box body forms a gas box filled with an insulated gas. The upperportion of the stainless steel welded sealed box body accesses an insulation bus and a lower portion accesses a cable wiring plug. The isolation switch component is installed in the stainless steel welded sealed box body through a grounding framework, and a closing button and an opening button for controlling the isolation switch component are installed on the external portion of the stainless steel welded sealed box body. The equipment has advantages that (1) insulation performance satisfies the requirements of a power frequency withstand voltage and an impulse withstand voltage; and (2) compared with dried and purified air, the insulated gas reduces an oxygen content by half, which can improve the heat capacity of a mixed gas, and reduce the oxygen corrosion of equipment parts.

Description

technical field [0001] The invention relates to a novel environment-friendly gas-insulated fully-enclosed fully-insulated ring network switchgear. Background technique [0002] Isolating switch is a device used in the circuit to connect, isolate, and switch the connection between the charged body and the electrical appliance. The isolating upper contact, the isolating lower contact and the grounding static contact of the existing isolating switch are arranged on the same insulator, which is prone to creepage and insulation deterioration, and the insulation reliability is poor. In the industry, it is called the phenomenon of isolated false fracture, but the present invention effectively solves the phenomenon of isolated false fracture. Furthermore, the rotating knife plate is fixedly installed on the rotating shaft and cannot be floated. The assembly requirements are strict, the production requirements are high, and the structure is complicated, which greatly increases the p...
