Device for rapidly cutting off remote visible high-voltage test power supply

Abstract

The invention discloses a device for rapidly cutting off a remote visible high-voltage test power supply, and the device disclosed by the invention mainly comprises a safety control part, a remote visible part and a video / wireless signal transceiving part, wherein the safety control part is composed of a power supply control cabinet arranged at the head end of a cable and a warning sensor at the rear end of the cable; the remote visible part mainly comprises a video display unit at the head end of the cable and a video monitor at the rear end of the cable; the video / wireless signal transceiving part is respectively connected with the warning sensor and the video monitor, and receives and processes signals; and the video / wireless signal transceiving part is in remote connection with the power supply control cabinet through video-wireless and / or wireless radio-frequency signals. The device disclosed by the invention has the characteristics of simple structure, convenience in use, reliable performance, capability of eliminating certain potential safety hazards existing in the current cable tests better, and the like.

Description

technical field [0001] The invention relates to a remote visible high-voltage test power supply quick cut-off device, which is mainly used in high-voltage cable test sites to ensure test safety and personal and property safety. Background technique [0002] Power cables are important equipment in the power system and shoulder the heavy responsibility of power distribution. With the development of the economy, cables are gradually replacing overhead lines in the urban distribution network. From factories to schools, from shopping malls to residential areas, cables are used more and more widely; therefore, ensuring the safe operation of cables is the key more and more important. The cable test, as an important type of work in the power system, is an important guarantee for the safe operation of the cable. To summarize the cable test, it has the following characteristics: [0003] 1) Wide application range. It mainly includes insulation test, withstand voltage test, nuclear ...

AI Technical Summary

Problems solved by technology

[0004] 2) It is often necessary to continuously apply high voltage to the test cable, the voltage is even as high as hundreds of thousands of volts, and the entire test time may be as long as 2 hours;

[0006] 4) Staff are required at the beginning and end of the cable test

[0011] The second is that the environment is complex and the personnel are numerous,

Therefore, "communication can only rely on words" leads to great security risks

[0016] 2) Poor communication quality, which can lead to misunderstanding

And only relying on the care of the terminal personnel cannot effectively guarantee the safety of the terminal

On the other hand, with the original communication method, the personnel at the head end cannot grasp the situation at the end, and the personnel at the end cannot know the liveliness of the cable in time; the communication between the personnel at the head and end is easily disturbed, resulting in misunderstanding; the power supply cannot be cut off quickly in case of danger, etc. There is a great potential safety hazard in this experiment

Safety issues are never small problems, let alone sit idly by and watch the existence of safety hazards
