Description

Technical Field

[0001] The present invention relates to the technical field of anti-intrusion devices, and in particular to an anti-intrusion alarm device for a control room of a 66 kV unmanned substation. Background Art

[0002] At present, the company has 9 66 kV substations, all of which are outdoor small-scale unmanned substations. The station sites are relatively remote and far away from residential areas. It is difficult to detect illegal intrusions in time. Once the control room equipment is invaded and causes a safety accident, the consequences are disastrous. Based on the above background, the development of unmanned substation anti-intrusion alarm devices is particularly important. The device sends an alarm signal when the control room door is opened, and can alarm in time when an intrusion occurs, realizing real-time monitoring of illegal intrusions in the control room, and providing strong support for substation safety protection. Summary of the invention

[0003] The technical solution of the present invention to solve the above technical problems is to provide a 66 kV unattended substation control room anti-intrusion alarm device, comprising:

[0004] A shell, one end of which is used to be fixed on the door frame, and a cavity is formed in the shell;

[0005] A limit baffle, the limit baffle being fixed on the cavity wall of the shell;

[0027] The present invention provides an anti-intrusion alarm device for a 66 kV unmanned substation control room, aiming to design an alarm device for automatically monitoring a substation control room.

[0028] The 66 kV unattended substation control room anti-intrusion alarm device proposed by the present invention will be described in a specific embodiment as follows:

[0029] In the technical solution of this embodiment, Figure 1 , Figure 2 , Figure 3As shown, a 66 kV unmanned substation control room anti-intrusion alarm device includes a shell 10, a limit baffle 20, a sliding baffle 30, a pull rod 40, a moving contact 50 and a static contact 60. One end of the shell 10 is used to be fixed on the door frame, and a cavity is formed in the shell 10; the limit baffle 20 is fixed on the cavity wall of the shell 10; the sliding baffle 30 is movably arranged in the cavity and is located on one side of the limit baffle 20; the pull rod 40 is movably passed through the limit baffle 20, one end of the pull rod 40 is fixed on the sliding baffle 30, and the other end is used to be connected to the door; the moving contact 50 is fixed on the sliding baffle 30; the static contact 60 is fixed on the limit baffle 20, and the static contact 60 is electrically connected to the measurement and control device of the substation through a cable.

[0030] Furthermore, the 66 kV unmanned substation control room anti-intrusion alarm device also includes a fixing plate 70 , which is fixed on the shell 10 ; the shell 10 is fixed on the door frame through the fixing plate 70 .

[0031] Furthermore, two limit baffles 20 are arranged in the cavity at intervals;

[0032] The 66 kV unmanned substation control room anti-intrusion alarm device also includes: a first spring 21 and a second spring 22, wherein the first spring 21 is arranged on the pull rod 40 and is located between the sliding baffle 30 and the limit baffle 20; the second spring 22 is arranged on the pull rod 40 and is located between the two limit baffles 20.

[0033] Furthermore, the 66 kV unmanned substation control room anti-intrusion alarm device also includes: a fixing frame 80, the fixing plate 70 is fixed to the end of the pull rod 40 away from the door frame, and the pull rod 40 is fixed to the door through the fixing frame 80.

[0034] Working principle: the housing 10 is fixed to the door frame through the fixing plate 70, and the pull rod 40 is fixed to the door through the fixing frame 80. When the door moves relative to the door frame, the pull rod 40 is pulled out from the housing 10, thereby driving the sliding baffle 30 to move toward the fixed baffle. When it moves to a preset distance, the moving contact 50 on the sliding baffle 30 abuts against the static contact 60 on the limit baffle 20. The static contact 60 is electrically connected to the measurement and control device of the substation through a cable, and is used to transmit the generated electrical signal to the measurement and control device of the substation. A group of telesignaling nodes on the NSD500M4 terminal block of the measurement and control device, after access, this normally open node automatically generates a group of telesignaling values ​​in the substation. The normally open node is in the disconnected state, and the corresponding telesignaling state on the measurement and control panel displays "open". When the alarm device is activated, the telesignaling state changes to "closed". Mark the position of the normally open node on the primary wiring diagram of the open3000 system at the master station, and associate it with the previously defined telesignal point number. Redefine this point number, and name the telesignal of this route as "the door of the control room of a certain substation is open", set it as an alarm signal, and record voice to correspond to it. The number of alarm voices can be set according to specific needs. In this way, once the alarm device is activated, the moving contact and the static contact are closed, the telesignal circuit of the control room is connected, and the state of the telesignal of this route changes from "open" to "closed". The state change signal of the telesignal is uploaded to the open3000 system of the control center through the optical fiber by the public measurement and control device NSD500M4. The action push screen function of the system is turned on to clearly display the action process of the alarm device. The words "the door of the control room of a certain substation is open" appear on the monitoring screen of the control center, and the corresponding voice prompts the control center operator "the door of the control room of a certain substation is open", and the action time is automatically displayed.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
