GIS equipment wall-penetrating cable hole plugging device

Technical Field

The utility model relates to a substation equipment technical field especially relates to a GIS equipment wears wall and uses cable hole plugging device.

Background

At present, the gas-insulated switchgear is a metal-enclosed switchgear that uses gas as an insulating medium instead of air under atmospheric pressure, or a part of the gas-insulated switchgear, and is also called a GIS (gas insulated switchgear). The combined type SF6 gas insulated switchgear is composed of a circuit breaker, a disconnecting switch, a grounding switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing line terminal and the like, all the equipment or components are sealed in a metal grounded shell, and SF6 gas with excellent insulating property and arc extinguishing property is filled in the metal grounded shell to serve as an insulating and arc extinguishing medium, so the combined type SF6 gas insulated switchgear is also called as an SF6 totally-enclosed combined electrical appliance. GIS devices have been widely operated around the world since the practical use in the 60's of the 20 th century.

GIS is widely used not only in the high-voltage and ultra-high voltage fields, but also in the ultra-high voltage field. Compared with a conventional open-type transformer substation, the GIS has the advantages of compact structure, small occupied area, high reliability, flexible configuration, convenience in installation, high safety and high environmental adaptability. The tubular bus shell of the gas-insulated totally-enclosed combined electrical appliance is tubular, SF6 insulating gas with certain pressure is filled in the tubular bus shell, and the SF6 insulating gas plays a role in insulating the tubular bus shell from an internal electrified conductor

However, in an indoor GIS substation, GIS equipment is arranged indoors in a dedicated GIS room, and the GIS equipment must be connected to a line incoming line or an adjacent main transformer to realize power transmission, and a GIS tubular bus bar thereof inevitably needs to penetrate through a wall. The GIS tubular bus penetrates through a hole of a wall body and must be blocked, so that the running safety of equipment is ensured.

In the prior art, the GIS cable hole is mainly directly plugged by cement mortar, but cement sand stone has a corrosion effect on the GIS tubular bus, and the accumulated corrosion can cause the GIS tubular bus to have the conditions of metal shell damage, air leakage and the like, so that great potential safety hazard is caused; and GIS equipment can have slight vibrations in the operation, and long-time vibrations can lead to the cement gravel and sand of shutoff department to appear not hard up the condition such as drop to appear.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving among the prior art and mainly directly adopting the direct shutoff of cement mortar to GIS cable hole shutoff, lead to GIS tubular bus to appear that metal casing damages gas leakage and cement sand stone the not hard up problem that drops, and the GIS equipment that proposes wears wall and uses cable hole plugging device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a GIS equipment is worn wall and is used cable hole plugging device, includes outer tube and gasbag, the gasbag slides and inserts and locates inside the outer tube, be equipped with a plurality of gas tubes on the gasbag, threaded connection has the inflation valve on the gas tube, the middle part of gasbag is equipped with the opening with outer tube parallel arrangement.

Preferably, a plurality of positioning rods are fixedly connected to the outer wall of the air bag, and positioning grooves corresponding to the positioning rods are formed in the inner wall of the outer sleeve.

Preferably, a plurality of the inflation tubes are respectively disposed at both ends of the airbag.

Preferably, a rubber sleeve is fixedly inserted on the inner wall of the through opening.

Preferably, sealing rings are fixedly bonded on the inner walls of the two ends of the outer sleeve.

Preferably, the edges of both ends of the air bag are fixedly connected with L-shaped stop levers.

Has the advantages that:

1. the outer sleeve is embedded into the wall hole, the air bag is inserted into the outer sleeve, the cable penetrates into the opening in the middle of the air bag, the air bag is inflated through the inflation tube, the outer wall of the air bag can be attached to the inner wall of the outer sleeve in the expansion process of the air bag, the inner wall of the opening is attached to the cable, and the sealing performance is guaranteed;

2. the setting of locating lever can prevent the rotation of gasbag, and the setting of rubber sleeve can play certain guard action to the opening inner wall simultaneously, and the canned type between gasbag and the outer tube can be guaranteed in the setting of sealing washer simultaneously, and L type pin can play certain limiting displacement to the gasbag simultaneously.
