Abstract

The utility model relates to a high voltage switch cabinet used for power network 12KV power distribution. A sheathing type cabinet has a relay room, an upper and lower breaker chamber, an upper and lower cable chamber and a main bus-bar chamber. The main bus-bar chamber is arranged at the middle. The main bus-bar is connected with the upper breaker through a contacting box. The upper breaker is orderly connected with a current transformer and a ground switch through a contacting box. The main bus-bar is connected with the lower breaker through the contacting box. The lower breaker is orderly connected with the current transformer and the ground switch through the contacting box. The utility model has the advantages of low cost, small volume, safe and convenient examine and repair, reasonable arrangement and novel design, being suitable to be used in 12KV power distribution power network.

Description

A kind of high-tension switch cabinet

The utility model belongs to the power technology field, relates in particular to a kind of high voltage switchgear that electrical network 12KV is subjected to distribution that is used for.

Along with the utilization that vacuum technique is more and more popularized in the high-voltage switch gear field, vacuum circuit-breaker has occupied absolute leading position in the 12KV switch.Because the vacuum circuit-breaker volume is little, this just makes switch cubicle be designed to bilayer becomes possibility.Present domestic switch cubicle roughly is divided into two kinds of fixed and withdraw-types, fixed existence maintenance difficulty, and bulky shortcoming, most of withdraw-type switchgears mostly are individual layer, exist the cost height, the shortcoming that floor space is big.

The purpose of this utility model be to overcome the deficiencies in the prior art and provide that a kind of cost is low, layout is new, overhaul high-tension switch cabinet easily.

The purpose of this utility model is achieved in that the armored cabinet is divided into relay bungalow, last breaker chamber, following breaker chamber, goes up cable vault, following cable vault and main bus bar chamber, the main bus bar chamber is positioned at the middle part, in the loop, upper strata, main bus bar in the main bus bar chamber is connected with last circuit breaker through contact box, last circuit breaker is connected with current transformer, earthed switch successively through contact box, in the lower floor loop, main bus bar in the main bus bar chamber is connected with following circuit breaker through contact box, and following circuit breaker is connected with current transformer, earthed switch successively through contact box.Last breaker chamber, time breaker chamber, last cable vault, following cable vault and main bus bar chamber are equipped with independently pressure release passage.

The utility model is combined as one with two switch cubicles, has advantages such as cost is low, volume is little, maintenance is convenient, rationally distributed, novel.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structure cutaway view of the present utility model.

As shown in Figure 1, armored cabinet of the present utility model is divided into relay bungalow 1, last breaker chamber, following breaker chamber, goes up cable vault, following cable vault and main bus bar chamber, main bus bar chamber 6 is positioned at the middle part, in the loop, upper strata, main bus bar in the main bus bar chamber is connected with circuit breaker 2 on the handcart-type through contact box 4, last circuit breaker 2 is connected with the current transformer 8 that keeps flat through contact box 4, is connected with earthed switch 9 by busbar again, and earthed switch 9 is via cable or overhead outlet.In the lower floor loop, the main bus bar in the main bus bar chamber 6 is connected with following circuit breaker 3 through contact box 4, and following circuit breaker 3 is connected with current transformer 5 through contact box 4, and electric current returns sensor 5 and is connected with earthed switch 7 through busbar.Last breaker chamber, time breaker chamber, last cable vault, following cable vault and main bus bar chamber are equipped with independently pressure release passage.Opening the back shrouding can overhaul the equipment of upper and lower cable vault and main bus bar chamber.

Claims
