Abstract
The utility model relates to a wire arrangement structure for a substation secondary equipment plate/cabinet, which comprises a secondary equipment plate/cabinet, wherein, an AC power supply circuit conducting wire and a plurality of groups of DC circuit conducting wires are arranged on the back plate of the secondary equipment plate/cabinet. The utility model is innovative in that the AC power supply return conducting wire is separated from other DC circuit conducting wires, that is, the AC power supply circuit conducting wire and the other DC circuit conducting wires are arranged in a vertically reversing manner or at intervals horizontally. By adopting the method of arranging the AC power supply return conducting wire and the DC circuit conducting wires in a separated manner, the utility model not only solves the problem of the AC power supply circuit affecting the DC circuit, with interference confined within an allowable scope, but also solves the problem of the AC power supply interfering in remote signal and remote control, thereby ensuring the normal and stable operation of the substation.
Description
Technical field
The utility model relates to substation secondary side apparatus field, particularly a kind of substation secondary device dish/cabinet winding displacement arrangement.
Background technology
At present, digitizer is used widely in transformer station.But; secondary devices such as existing transforming plant protecting dish/cabinet are on the wire structures of its backboard; usually winding displacement mixes the DC loop lead of ac power supply circuit lead and digitizer; cause AC power that the DC loop of digitizer is produced coupled interference thus; thereby cause mistake to send out problems such as rub-out signal; and also there is certain influence in remote signal, influence the normal operation of digital transformer substation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of substation secondary device dish/cabinet winding displacement arrangement, the coupled interference problem that it can avoid transformer station's ac power supply circuit that the digitizer DC loop is caused.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of substation secondary device dish/cabinet winding displacement arrangement, comprise secondary device dish/cabinet, on the backboard of this secondary device dish/cabinet, be furnished with ac power supply circuit lead and many group DC loop leads, it is characterized in that: ac power supply circuit lead and other DC loop lead are separated bus-bar construction, are specially: ac power supply circuit and other DC loop lead are reverse bus-bar construction or between left and right every bus-bar construction up and down.
And, described ac power supply circuit lead and other DC loop lead between left and right when bus-bar construction, its ac power supply circuit lead and other DC loop lead winding displacement spacing distance are not less than 5cm.
And described ac power supply circuit lead is emitted on separately in the wire casing.
Advantage of the present utility model and beneficial effect are:
Substation secondary device dish of the present utility model/cabinet winding displacement arrangement, by ac power supply circuit lead and DC loop lead being carried out the wire arranging method of apart arrangement, solved the influence of ac power supply circuit to DC loop, Interference Control in the allowed band, solved the interference problem of AC power, guaranteed normal, the stable operation of transformer station remote signalling, remote control.
Description of drawings
Fig. 1 is first kind of winding displacement arrangement of the utility model secondary device dish/cabinet schematic diagram;
Fig. 2 is the another kind of winding displacement arrangement of a utility model secondary device dish/cabinet schematic diagram.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of substation secondary device dish/cabinet winding displacement arrangement, comprise secondary device dish/cabinet, be furnished with ac power supply circuit lead 2 and many group DC loop leads 3. its innovation parts are on the backboard 1 of this secondary device dish/cabinet: ac power supply circuit lead and other DC loop lead are separated bus-bar construction. be specially: ac power supply circuit and other DC loop lead are reverse bus-bar construction up and down, as shown in Figure 1. ac power supply circuit and other DC loop lead are between left and right every bus-bar construction, as shown in Figure 2. at ac power supply circuit lead and other DC loop lead between left and right every bus-bar construction the time, its ac power supply circuit lead and other DC loop lead winding displacement spacing distance are not less than 5cm, and shorten and DC loop cabling side by side as far as possible. and, the ac power supply circuit lead is emitted on separately in the wire casing, make the independent cabling of ac power supply circuit. the bus-bar construction that carries out apart arrangement by ac power supply circuit lead and DC loop lead with secondary device dish/cabinet, Interference Control in the allowed band, has been solved the influence problem of ac power supply circuit to DC loop.
