Abstract

Products applied to a 12KV, 50Hz power system, relate to a switching device as distribution of electric power and control, specifically to an SF6 complete insulating and panseal rig net switch cabinet. The rig net switch cabinet comprises a cabinet body, an operating mechanism and an air box, wherein the air box and the operating mechanism are arranged in the cabinet body; bus bars electrically connected and at least a triple-pole switch are arranged in the air box; a coil in bushing is electrically connected with a lower bus bar; at least a coil out bushing is electrically connected with an upper bus bar, wherein the coil out bushing is electrically connected with the triple-pole switch, and is arranged at a grounding end of the triple-pole switch; the coil in bushing and the coil out bushing are respectively arranged on two upper sides of the cabinet body. When the rig net switch cabinet is used as the coil in cabinet, the outgoing line is provided with grounding functions, and expansion is agile. The invention is an SF6 complete insulating and panseal rig net switch cabinet with convenient connection.

Description

A kind of loop-network switch cabinet

Technical field

This product is applied to 12kV, 50Hz electric power system, relates to a kind of switchgear as power distribution, control, relates in particular to a kind of SF ₆Full-insulated full-sealed loop-network switch cabinet.

Background technology

Present SF ₆The full-insulated full-sealed loop-network switch cabinet of gas has a series of mesohigh products, and in this series products, parts of all high pressure all are sealed in and are full of SF ₆Gas tank in, be not subjected to the variable effect of external environment, be more suitable for using than general air insulation switch cubicle in the abominable area of environment, the scope of application is wider and fail safe is higher, but general switch cubicle does not have the outlet grounding function when using to the inlet wire function, bring the hidden danger of user power utilization, have the problem of Electrical Safety aspect.

Summary of the invention

The loop-network switch cabinet that the purpose of this invention is to provide a kind of Electrical Safety.

For achieving the above object, the invention provides following technical scheme:

Loop-network switch cabinet comprises

Cabinet, operating mechanism and gas tank, described gas tank and operating mechanism all are positioned at cabinet;

Bus row and at least one triple-pole switch of being electrically connected are arranged in the gas tank;

One entrance bushing and Down Highway row are electrically connected;

At least one outlet sleeve pipe and Up Highway UHW row are electrically connected;

Wherein,

Described outlet sleeve pipe and Up Highway UHW row are electrically connected by triple-pole switch, and the outlet sleeve pipe is at the earthing position end of triple-pole switch;

Described entrance bushing and outlet sleeve pipe lay respectively at the both sides, top of cabinet.

When above-mentioned loop-network switch cabinet uses as the incoming line cabinet function, go out the tape grounding function, and expansion is a kind of SF easy to connect flexibly ₆Full-insulated full-sealed loop-network switch cabinet.

Description of drawings

Fig. 1 is the cutaway view of a direction of the utility model loop-network switch cabinet;

Fig. 2 is the cutaway view of another direction of the utility model loop-network switch cabinet.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

When the utility model loop-network switch cabinet uses as the incoming line cabinet function, go out the tape grounding function, and expansion flexibly, the full-insulated full-sealed loop-network switch cabinet of SF6 easy to connect.

A kind of SF ₆Full-insulated full-sealed loop-network switch cabinet comprises SF ₆Gas tank 1, operating mechanism 6 and cabinet 5, gas tank 1 and operating mechanism 6 all are positioned at cabinet 5.There is the bus that advances that is electrically connected to arrange, go out bus row, organize the triple-pole switch 2 of three stations etc. more in the gas tank 1.Entrance bushing 7 is electrically connected into bus row, and outlet sleeve pipe 4 is electrically connected out bus row.Entrance bushing 7 is positioned at the upper left-hand of cabinet 5, and outlet sleeve pipe 4 is positioned at the upper right of cabinet 5, and entrance bushing 7 and outlet sleeve pipe 4 can have a plurality of.Outlet sleeve pipe 4 is electrically connected by triple-pole switch 2 with going out bus row, and outlet sleeve pipe 4 is at the earthing position end of triple-pole switch 2.That is to say and to realize leading-out terminal band grounding function, better ensure user's Electrical Safety.Triple-pole switch 2 pairing three kinds of states of three stations are respectively: the first, disconnect, promptly advance bus row and go out bus row disconnection; The second, close a floodgate, promptly advance bus row and go out bus and arrange and be electrically connected; The 3rd, outlet sleeve pipe ground connection promptly, with outlet sleeve pipe 5 ground connection, is realized the outlet grounding function.

From said structure as can be known, the entrance bushing 7 of above-mentioned loop networks switch and outlet sleeve pipe 5 lay respectively at the both sides of cabinet top, that is, and and the outlet of sidepiece inlet wire sidepiece.

Certainly, the utility model loop-network switch cabinet also can be out of shape by other.In a word, doing conspicuous change according to the prompting of the foregoing description, and other every changes that do not break away from essence of the present invention, all should be included within the described scope of claim.
