Description
Technical field
The utility model relates to the box Switching Station in power technology field, especially a kind of box Switching Station with self-powered function.
Background technology
As shown in Figure 1, existing box Switching Station is that ring main unit 2 and power supply communication screen 3 are installed in housing 1, then be linked in power supply communication screen by external power source, power supply communication screen becomes DC48V by the AC220V of input and carries out electric operating use to ring main unit, and gives the power supply of the communication apparatus in power supply communication screen.Often need trench excavation and external power source is incorporated into box Switching Station, cable laying, installs the work such as control cabinet, and not only workload is very large, and cost is very high.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, and a kind of box Switching Station with self-powered function that can reduce construction volume and construction cost is provided.
The purpose of this utility model realizes by following technological means:
A kind of box Switching Station with self-powered function, comprise housing, ring main unit and power supply communication screen, ring main unit and power supply communication screen are arranged in housing, ring main unit and the electrical connection of power supply communication screen, it is characterized in that: a station dry-type transformer is installed in housing, ring main unit is connected with the high-pressure side of dry-type transformer with station by cable, stands and uses the low-pressure side of dry-type transformer to connect power supply communication screen by electric wire.
And one end docking station of described cable connects the high-voltage connection terminal of ring main unit with the high-pressure side of dry-type transformer, the other end, the stage casing of cable is placed in enclosure interior or passes housing and be positioned at the outside of housing.
Advantage of the present utility model and good effect are:
1, this box Switching Station installation station's dry-type transformer in housing, stands with the high-pressure side connection ring main unit of dry-type transformer, and low-pressure side connects power supply communication screen.This transformer can become AC220V low tension by the 10KV of ring main unit, then low tension is sent into power supply communication screen, realizes normal power supply.Adopt this structural design need not dig cable ditch cable laying, therefore can save a lot of costs, and can improve construction schedule.
All simple and convenient, easy operatings that is connected of 2, standing and shielding with the installation of dry-type transformer and with ring main unit and power supply communication, can not bring extra inconvenience to construction.
3, the utility model is a kind of box Switching Station with self-powered function ingenious, that improve rationally, be easy to realization that designs, and uses this box Switching Station can simplify workflow, reduces workload, accelerating construction progress, reduction construction cost.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection range of the present utility model with this.
Have a box Switching Station for self-powered function, comprise housing 1, ring main unit 2 and power supply communication screen 3, ring main unit and power supply communication screen are arranged in housing, ring main unit and the electrical connection of power supply communication screen.
Innovative point of the present utility model is: a dry-type transformer 4 for station is installed in housing, ring main unit is connected with the high-pressure side of dry-type transformer with station by cable 5, its concrete connected mode is: one end docking station of cable is used the high-pressure side of dry-type transformer, the other end connects the high-voltage connection terminal of ring main unit, the stage casing of cable can be placed on enclosure interior, can also and be placed in the cable trough of outside below through housing.Stand and use the low-pressure side of dry-type transformer to connect power supply communication screen by electric wire.
Operation principle of the present utility model is:
Ring main unit, power supply communication screen and station are arranged in housing with dry-type transformer, and with cable, the 10KV high-tension electricity of ring main unit is introduced to the high-pressure side of arriving at a station with dry-type transformer, by transformer, 10KV high-tension electricity is become to AC220V low tension, be linked into again in power supply communication screen, power supply communication screen becomes DC48V by the AC220V of input and carries out electric operating use to ring main unit, and gives the power supply of the communication apparatus in power supply communication screen.
