Abstract
The utility model relates to high voltage power distribution equipment and discloses a mid-cabinet installed with a straight-through current transformer. The mid-cabinet comprises a cabinet body, wherein an instrument room, a circuit breaker room, a cable room, a main busbar room and the straight-through current transformer are arranged in the cabinet body, the instrument room is located at the front side of the upper part of the cabinet body, the circuit breaker room is located at the front side of the middle part of the cabinet body, the cable room is located at the lower part of the cabinet body, the main busbar room is located at the rear side of the upper part of the cabinet body, an isolation space is arranged between the instrument room and the main busbar room, and the instrument room is communicated with the circuit breaker room. The mid-cabinet provided by the utility model is compact in structure and is domestic first, after the mid-cabinet is adopted, a traditional current transformer is changed into the straight-through current transformer, and copper bar busbars from a lower contact terminal box to a grounding knife and a cable are directly penetrated through the transformer to reduce the copper bar lapping surface and avoid the equipment of being burnt by heat generated in the operation process, thereby having high practicability.
Description
Technical field
The utility model relates to a kind of high-tension distribution equipment, relates in particular to a kind of middle-placed switch cabinet that straight-through current transformer is installed.
Background technology
Along with the development of power transformation, controller switching equipment intelligent control, 10kV equipment adopts the middle-placed switch cabinet form in a large number, and the demand of simultaneously large electric current middle-placed switch cabinet is also more and more.In traditional middle-placed switch cabinet, current transformer must the two ends contact be connected with copper bar.And along with electric current increase, the quantity of copper bar just increases, the faying surface of copper bar just increases, and the heating and burn out equipment while too much easily causing the equipment operation of copper bar faying surface.
Summary of the invention
The utility model, for the defect existed in prior art, provides a kind of compact conformation, easy to use, and the safe and reliable middle-placed switch cabinet that straight-through current transformer is installed has effectively been avoided equipment when operation heating and burnt out equipment, has very high practicality.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of middle-placed switch cabinet that straight-through current transformer is installed, comprise cabinet, be provided with control room, the breaker chamber that is positioned at front side, cabinet middle part, the cable vault that is positioned at the cabinet bottom that is positioned at front side, cabinet top, main bus bar chamber and the straight-through current transformer that is positioned at cabinet top rear side in described cabinet, be provided with insulating space between described control room and main bus bar chamber, described insulating space is connected with breaker chamber.
As preferably, indoor wall bushing, power source bus, upper contact head box, the lower contact box of being provided with of described main bus bar, described power source bus is connected with the upper contact head box by wall bushing; Described lower contact box is connected with earthing with the cable in cable vault after passing straight-through current transformer by copper bar bus line.
As preferably, between described cable vault and main bus bar chamber, by metallic plate, to separate, described straight-through current transformer is arranged on metallic plate.
As preferably, described control room, breaker chamber, cable vault, main bus bar chamber correspondence respectively are provided with control room's cabinet door, breaker chamber cabinet door, cable vault's cabinet door, main bus bar chamber cabinet door.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model compact conformation, for domestic the first, after adopting this middle-placed switch cabinet, because traditional current transformer has changed the punching instrument transformer into, lower contact box directly passes to the copper bar bus line of earthing and cable from instrument transformer, reduce the copper bar faying surface, avoided equipment when operation heating and burn out equipment, there is very high practicality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1, with embodiment, the utility model is described in further detail:
Embodiment 1
A kind of middle-placed switch cabinet that straight-through current transformer is installed, as shown in Figure 1, comprise cabinet, be provided with the control room 2 that is positioned at front side, cabinet top, breaker chamber 3, the cable vault 4 that is positioned at the cabinet bottom, the main bus bar chamber 5 that is positioned at cabinet top rear side and the straight-through current transformer 7 that is positioned at front side, cabinet middle part in cabinet, be provided with insulating space 8 (this insulating space 8 consists of two cavitys that form between metallic plate that be arranged in parallel) between described control room 2 and main bus bar chamber 5, described insulating space 8 is connected with breaker chamber 3.Be provided with wall bushing 52, power source bus 53, upper contact head box 61, lower contact box 62 in described main bus bar chamber 5, described power source bus 53 is connected with upper contact head box 61 by wall bushing 52; Described lower contact box 62 is connected with earthing with the cable in cable vault 4 after passing straight-through current transformer 7 by copper bar bus line.
Between described cable vault 4 and main bus bar chamber 5, by metallic plate 9, separate, described straight-through current transformer 7 is arranged on metallic plate 9.
Described control room 2, breaker chamber 3, cable vault 4, main bus bar chamber 5 correspondence respectively are provided with control room's cabinet door 21, breaker chamber cabinet door 31, cable vault's cabinet door 41, main bus bar chamber cabinet door 51.
In the utility model middle-placed switch cabinet, lower contact box directly passes from straight-through current transformer 7 to the copper bar bus line of earthing, the copper bar bus line that connects lower contact box and earthing only has two places that faying surface is arranged at lower contact box and earthing, and the copper bar faying surface of the lower contact of traditional middle-placed switch cabinet connection and earthing has everywhere: be respectively lower contact, punching instrument transformer end of incoming cables, punching instrument transformer leading-out terminal, earthing, so just reduced the faying surface of copper bar, avoided equipment when operation heating and burn out equipment.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
