Abstract

The utility model relates to a high voltage loop-network switch cabinet which comprises a bus chamber. The bus chamber is arranged at the upper part of the switch cabinet; after being connected, three insulators arranged in the bus chamber pass through a housing of the bus chamber to be connected with one end of an upper disconnector; the other end of the upper disconnector is connected with a first current transformer; the first current transformer is connected with a power supply sequentially through a circuit breaker, a second current transformer and a lower disconnector; a lightning arrester is arranged at the lower part of the circuit breaker; the switching-on and switching-off of the high voltage loop-network switch cabinet are controlled by the upper disconnector and the lower disconnector; and the lightning protection is carried out by the lightning arrester. The high voltage loop-network switch cabinet has compact structure; the size can be reduced; the performance of the product can also be ensured; and the high voltage loop-network switch cabinet can be placed in a 35KV box-type substation.

Description

The high pressure ring switch cubicle

Technical field

The utility model relates to the switch cubicle technical field, particularly the high pressure ring switch cubicle.

Background technology

Existing market 35KV transformer station demand increases day by day; And construction building structure transformer station expense is huge, and the 35KV box-type substation becomes the substitute of existing building structure transformer station gradually, and the existing 35KV switchgear in market is bulky; Height dimension is too high, the 35KV box-type substation of can not packing into.

The utility model content

The technical problem that the utility model solved is to provide the high pressure ring switch cubicle, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved adopts following technical scheme to realize:

The high pressure ring switch cubicle; Comprise bus-bar room, bus-bar room places switch cubicle top, three insulator A of configuration in the bus-bar room; B with pass the shell of bus-bar room after C links to each other and an end of last isolating switch links to each other; The other end of last isolating switch links to each other with first current transformer, and first current transformer links to each other with power supply through circuit breaker, second current transformer, following isolating switch successively, and lightning arrester places the circuit breaker bottom.

Three insulator A of described main bus bar chamber, B and C adopt the inverted triangle arrangement mode.

Described isolating switch and first current transformer employing upside-down mounting mounting means gone up.

The described down isolating switch and second current transformer adopt and land mounting means.

Described main bus bar chamber adopts insulating barrier to separate.

The operation principle of the utility model is: control the Kai Heguan of high pressure ring switch cubicle through last isolating switch and following isolating switch, and take shelter from the thunder through lightning arrester.

Beneficial effect

Because the utility model compact conformation, can reduced volume, can guarantee properties of product again simultaneously, can insert the 35KV box-type substation.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

The high pressure ring switch cubicle; Comprise bus-bar room 1, bus-bar room 1 places switch cubicle top, three insulator A of configuration in the bus-bar room 1; B with pass the shell of bus-bar room 1 after C links to each other and an end of last isolating switch 2 links to each other; The other end of last isolating switch 2 links to each other with first current transformer 3, and first current transformer 3 is successively through circuit breaker 4, second current transformer 5, isolating switch 6 links to each other with power supply 7 down, and lightning arrester 8 places circuit breaker 4 bottoms.

Three insulator A of described main bus bar chamber 1, B and C adopt the inverted triangle arrangement mode.

Described isolating switch 2 and first current transformer, the 3 employing upside-down mounting mounting meanss gone up.

The described down isolating switch 6 and second current transformer 5 adopt and land mounting means.

Described main bus bar chamber 1 adopts insulating barrier to separate.

The operation principle of the utility model is: control the Kai Heguan of high pressure ring switch cubicle through last isolating switch 2 and following isolating switch 6, and take shelter from the thunder through lightning arrester 8.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent thereof.
