Abstract
The utility model discloses a safety door for a box-type transformer substation, comprising a door frame and a door panel arranged on the door frame, wherein the door panel is provided with a high voltage electrification display which detects whether a high voltage circuit inside a box body is electrified and an electronic lock which controls the door panel to open and close, and the high-voltage electrification display is electrically connected with the electronic lock. Whether the high voltage circuit inside the box body can be detected by virtue of the high voltage electrification display on the door panel, the electronic lock is controlled to be not opened when the high voltage circuit is electrified, an electrification operation is prevented, a safety accident is avoided, and operational safety is improved.
Description
Technical field
The utility model relates to transformer station's technical field, especially relates to a kind of cubicle-type substation exit.
Background technology
Box-type substation is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, by indoor, the outdoor close-coupled controller switching equipment of certain connection plan row's all-in-one-piece prefabrication, be about to the functions such as high powered, transformer pressure-reducing, low-voltage distribution and organically combine.The door of existing box-type substation mostly is the door-plate that steel plate is made, and is provided with mechanical lock at door-plate, and when opening cabinet door, whether can not the detection display casing interior high-tension circuit is charged, and poor stability is prone to security incident.
The utility model content
Whether technical problem to be solved in the utility model provides a kind of cubicle-type substation exit, charged to reach the high-tension circuit of opening in the Men Shineng detection casing, improves the purpose of processing safety.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cubicle-type substation exit, comprise door frame and the door-plate that is located on the door frame, described door-plate is provided with and detects casing internal high pressure circuit whether charged high-voltage charge display device and the electronic lock of control door-plate open and close, and described high-voltage charge display device and electronic lock are electrically connected.
Described high-voltage charge display device is provided with the instrument connection that can carry out the nuclear phase test.
The utility model compared with prior art, whether have the following advantages: it is charged to detect casing internal high pressure circuit by the high-voltage charge display device on the door-plate, and the control electronic lock can not be opened when the internal high pressure circuit is charged, prevents hot line job, avoid occurring security incident, improve fail safe.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model cubicle-type substation exit organigram.
Among the figure: 1. door frame, 2. door-plate, 3. high-voltage charge display device, 4. electronic lock.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of cubicle-type substation exit, comprise door frame 1 and the door-plate 2 that is welded on the door frame 1, be provided with at door-plate 2 and detect casing internal high pressure circuit whether charged high-voltage charge display device 3 and the electronic lock 4 of control door-plate 2 open and close, high-voltage charge display device 3 and electronic lock 4 are electrically connected.Whether detect casing internal high pressure circuit by the high-voltage charge display device 3 on the door-plate 2 charged, when detecting the internal high pressure circuit when charged, high-voltage charge display device 3 output electronic signals control electronic locks 4 can not be unlocked, and prevent hot line job, avoid occurring security incident, improve processing safety.Detect the internal high pressure circuit when not charged, electronic lock just can be unlocked.
Further, in order to make things convenient for the nuclear phase operation, be provided with the instrument connection that can carry out the nuclear phase test at high-voltage charge display device 3.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
Claims (2)
