Abstract
A high-voltage PT cabinet comprises a cabinet body. The inner part of the cabinet body is divided into an instrument chamber arranged on the upper part of the front side, a handcart chamber arranged on the middle part of the front side, a front lower chamber arranged on the lower part of the front side, a bus chamber arranged on the upper part of the rear side and a cable chamber arranged on the lower part of the rear side. A handcart device is arranged in the handcart chamber. An upper contact of the handcart device is connected with a copper bar in the bus chamber through an upper static contact, and a lower contact is connected with a copper bar in the cable chamber through a lower static contact. A voltage transformer is installed on the lower part of the cabinet body. A, B and C phases of wiring ends of the voltage transformer is arranged on the side opposite to an N phase wiring end. The A, B and C phases of wiring ends are arranged in the cable chamber. A secondary terminal is arranged in the front lower chamber so as to enable the copper bar between the A, B and C phases of wiring ends and the lower static contact to extend vertically, so that the copper bar is reasonably arranged, the occupied space is reduced, and the cost is saved.
Description
Technical field
The present invention relates to a kind of high pressure P T cabinet.
Background technology
nullKnown，The control room being positioned at forward upper it is separated into inside the cabinet of high pressure P T cabinet、The handcart room at middle part, front side and the front lower room of lower front，It is positioned at the bus-bar room of upper back and the cable vault of back lower，Handcart room is provided with cart device，The upper contact head of cart device is connected with the copper bar in bus-bar room by upper static contact，Lower contact is connected with the copper bar in cable vault by lower static contact，Cable vault is provided with the earthed switch being connected with copper bar，Cabinet is provided with voltage transformer in bottom，The A of voltage transformer、B、The C line end that connects is arranged in front lower room，The N line end that connects is arranged in cable vault，Secondary terminals is arranged in front lower room，Connect switch and take more space，Said structure causes connecting lower contact and A、B、C connects the copper bar of line end cannot rational deployment，Need copper bar is repeatedly bent，Not only increase copper bar consumption，Copper bar takes up room greatly，And easily cause A、B、The problem that C phase copper bar does not reach, to the distance of N phase or cabinet steel plate, the electric clearance that national standard requires.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of can rational deployment copper bar reduce cost high pressure P T cabinet.
The purpose of the present invention realizes by following technical solution:
A kind of high pressure P T cabinet, including cabinet, the control room being positioned at forward upper it is separated into inside cabinet, the handcart room at middle part, front side and the front lower room of lower front, it is positioned at the bus-bar room of upper back and the cable vault of back lower, handcart room is provided with cart device, the upper contact head of cart device is connected with the copper bar in bus-bar room by upper static contact, lower contact is connected with the copper bar in cable vault by lower static contact, it is characterized in that: cabinet bottom is provided with voltage transformer, the A of voltage transformer, B, the C line end line end that connects with N that connects is arranged on relative both sides, A, B, the C line end that connects is arranged in cable vault, secondary terminals is arranged in front lower room, make to be connected to A, B, the copper bar that C connects between line end and lower static contact vertically extends.
Further, the copper bar that described A, B, C connect between line end and lower static contact is connected to earthed switch, and this earthed switch is arranged on the rear side of described cable vault.
Further, the described N line end that connects is arranged in described front lower room.
Further, described cart device includes the fuse that is arranged between upper and lower contact.
Further, described cart device includes spark gap.
There is advantages that
The line end that A, B, C of voltage transformer connected is arranged in cable vault, enabling to be connected to the copper bar that A, B, C connect between line end and lower contact and vertically extend layout, thus saving copper bar, reducing cost, and reduce copper bar to take up room, it is simple to copper bar makes, installs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With reference to shown in Fig. 1, a kind of high pressure P T cabinet, including cabinet A, the front lower room 3 being positioned at handcart room 2 and lower front in the middle part of the control room 1 of forward upper, front side it is separated into inside cabinet A, it is positioned at the bus-bar room 4 of upper back and the cable vault 5 of back lower, handcart room 2 is provided with cart device 6, the upper contact head 62 of cart device 6 is connected with the copper bar 41 in bus-bar room by upper static contact 61, lower contact is connected with the copper bar 8 in cable vault 5 by lower static contact, and it is not shown that lower static contact is arranged in contact box 63.Cabinet A bottom is provided with voltage transformer 7, A, B, C of voltage transformer 7 line end 71 line end 72 that connects with N that connects is arranged on relative both sides, A, B, C line end 71 that connects is arranged in cable vault 5, secondary terminals 73 and the N line end 72 that connects is arranged in front lower room 3, make to be connected to the copper bar 8 that A, B, C connect between line end 71 and lower static contact and vertically extend layout, thus reasonable Arrangement copper bar, reduce cost.The copper bar 8 that A, B, C connect between line end and lower static contact is connected to earthed switch 9, and this earthed switch 9 is arranged on the rear side mounting rail of cable vault 5.
Cart device 6 includes spark gap and the fuse being arranged between upper and lower contact.
The above, be only presently preferred embodiments of the present invention, therefore can not limit scope of the invention process with this, and the equivalence namely made according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
