With the overall transformation and development of power transmission, distribution and transformation networks, the number of switching stations in various places is greatly increased, and the switching stations are power facilities for supplying power to surrounding power utilization units by high-voltage power and are one of key links for transmitting the power from high voltage to low voltage. The switching station is equivalent to the extension of a substation bus and plays a role of power supply support in regional power supply. The usual operating voltage in a switching station is 10kV, which is relatively high. The cabinet door of the switching station is in a closed state under a normal condition, and an irrelevant person cannot open the cabinet door without a key. In an area where the use of electric power is concentrated, a plurality of switching stations are generally arranged, the same switching station is generally provided with a plurality of cabinet doors, and keys of different cabinet doors are generally different. Therefore, when the switching station fails, a maintenance technician in the area usually needs to carry a large number of keys to the switching station, and then select the key corresponding to the failed part to open the cabinet door, and then perform maintenance work. Carrying a large number of keys is not conducive to simplifying the work of maintenance personnel, and once a key is lost or a wrong key is taken, it is necessary to return to the workstation again to obtain a spare key or a correct key, thus wasting time to and fro. If the same switching station adopts a single key to match all the locks, the potential safety hazard that the switching station is easy to be opened by mistake by irrelevant personnel exists.

Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a cabinet 4 is provided on the inner side surface of the door of the opening/closing station. The top of the case 4 is provided with a movable cover plate 3, and one side of the movable cover plate 3 is hinged with one side of the case 4. The case 4 is fixed on the inner side surface of the cabinet door 2. The door 2 of the switching station is hinged with one side of the door frame 1. The door frame 1 is provided with a lock catch 5. The case 4 is internally provided with a router 7, a control host 8, an electromagnetic lock 9 and a storage battery pack 6. The router 7 is connected with the control host 8, the control host 8 is electrically connected with the electromagnetic lock 9, and the storage battery 6 is respectively electrically connected with the router 7, the control host 8 and the electromagnetic lock 9 and supplies power to the three components. The electromagnetic lock 9 is installed on the cabinet door 2, and the bolt 901 and the 5 cooperations of hasp of electromagnetic lock 9 satisfy the basic function of unblanking and shutting the lock. The utility model discloses a router 7 receives maintenance work personnel's wireless control signal is because, router 7 receives wireless signal's scope is limited, if and only can receive the corresponding signal of unblanking or closing the lock when communication equipment is located near the switching station, so can improve the security of switching station, avoid by maintenance technical personnel maloperation and lead to the switching station to open the cabinet door and not perceived by maintenance technical personnel, and then avoid taking place the incident.

The outer surfaces of the case 4 and the movable cover plate 3 are coated with conductive paint. Because the normal working voltage of the switch is 10kV, a certain magnetic field can be generated, in order to avoid the interference of the wireless communication between the control host 8 and the router 7, the outer surfaces of the case 4 and the movable cover plate 3 are coated with conductive paint, so that the electromagnetic interference generated by strong current circuits and equipment in the switch station can be effectively prevented, and the stability of the wireless communication is ensured.

The control host 8 is composed of a PCB circuit board and a wireless communication module, and the wireless communication module is installed on the PCB circuit board. The PCB circuit board needs to satisfy the following characteristics: a wireless communication interface is provided. The optional model of circuit board is numerous on this basis, considers the comprehensiveness of cost and function, and the PCB circuit board that uses the STC15 chip as the core is preferred to select here, satisfies the utility model discloses a basic requirement. The wireless communication module needs to satisfy the following characteristics: a real-time operating system is supported. On the basis of the above, the wireless communication module can be selected from various models, and the ESP8266 wireless communication module is preferably selected in consideration of cost performance. The ESP8266 wireless communication module is connected with the PCB through a wireless interface. The ESP8266 wireless communication module communicates with the router 7 in real time when operating normally. The actual working process is as follows: the user sends an unlock signal to the router 7 through the communication means.
