Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides a control device for high-voltage tests, including an isolating switch 1 for controlling the on-off of the high-voltage test circuit, a main control box 2 and several hand-held devices 3, and the main control box 2 includes a control module 21 and The first alarm 22 electrically connected with the control module 21, the control module 21 is used to control the disconnector 1 opening and closing to realize the on-off of the high voltage test circuit, the hand-held device 3 includes a central processing unit 31 and is electrically connected with the central processing unit 31 The positioning module 32 and the second alarm 33, during the high-voltage test, the monitoring personnel carry a hand-held device 3 with them, and the position of the monitoring personnel can be located in real time by setting the positioning module 32. Communication connection, the central processing unit 31 is provided with a preset safety ...

Embodiment 2

[0037] The main difference between this embodiment and Embodiment 1 is that the main control box includes a display module.

[0038] Such as figure 2 As shown, the main control box 2 includes a display module 23, and the display module 23 includes several display parts for displaying the position of the handset 3. The number of display parts and the handset 3 are equal and associated with each other. The advantage of such setting is that the display part can correspond to the position of the display hand-held device 3, which is convenient for the staff who manage the high-voltage test circuit to observe the status of each monitoring personnel at the first time, further ensuring the safety of the monitoring personnel and the high-voltage test equipment, thereby Ensure that the high pressure test can be carried out safely.

[0039] The display part is three lights of different colors, which respectively represent that the handheld device 3 is located in the preset safety zone,...

Embodiment 3

[0042] The main difference between this embodiment and the second embodiment is that the isolating switch is provided with a locking structure for preventing the isolating switch from being closed by mistake.

[0043] Such as image 3 As shown, the isolating switch 1 is provided with a locking structure 4 for preventing the isolating switch 1 from being closed by mistake. The locking structure 4 is electrically connected to the control module 21. When each hand-held device 3 is in a preset safe zone, the control module 21 controls the locking structure. 4 to unlock. The advantage of this setting is that the locking structure 4 cooperates with the isolating switch 1 to provide double protection for the high-voltage test circuit, and further ensures that only when all monitoring personnel are in the preset safety zone, the high-voltage test circuit will be connected, ensuring the safety of the monitoring personnel and the high-voltage test equipment. Safety, so as to ensure tha...

Abstract

The invention provides a control device for high voltage test. The control device comprises an isolation switch, a main control box and a plurality of hand-held devices, wherein the main control box comprises a control module and a first alarm, each monitoring person carries a hand-held device, the hand-held device comprises a central processing unit, a positioning module and a second alarm, the control module is connected with the central processing unit via wireless communication, the central processing unit is provided with a preset safety zone, a preset alarm zone and a preset danger zone,the central processing unit processes position data measured by the positioning module and determines the position of the hand-held device, and when each hand-held device is in the preset safety zone, the control module can control the isolation switch to be closed; when one of the hand-held devices is in the preset alarm zone, the first alarm and the second alarm are started to prevent the monitoring personnel from entering the preset alarm zone by mistake; and when the position of one or more hand-held devices is in the preset danger zone, the control module controls the isolation switch tobe opened to ensure the safety of the monitoring personnel, so that the high voltage test can be performed safely.

Description

technical field [0001] The invention relates to the technical field of control devices, in particular to a control device for high-voltage tests. Background technique [0002] During the high-voltage test, especially the withstand voltage test, the applied voltage is high, the voltage action time is long, and there are many unpredictable factors. At present, multiple monitoring personnel are used to walk around the test device for monitoring. If the monitoring personnel's ability to identify the safety range is weak, it is easy to cause safety accidents. Contents of the invention [0003] The purpose of the present invention is to provide a management and control device for high-voltage testing, so as to ensure that the high-voltage testing can be carried out safely. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a management and control device for high-voltage tests, including an isolating switch for control...
