Problems solved by technology

This switch does not have an alarm function when the line fails and trips, and the power supply personnel can only respond passively, that is, they often rely on the user to call to inquire about the power outage; if all are replaced with intelligent switches, the equipment cost alone will be as high as several million , a huge investment

Embodiment Construction

[0019] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] A method for indicating the action of a 10kV line switch, comprising the following steps: ① placing the 10kV line switch action indicator on the top of the 10kV line switch, and bonding the four corners with superglue; attaching the DTU antenna to the box of the 10kV line switch or the 10kV line On the opening and closing operating lever of the switch; ②Using solar integrated power supply for power supply, using the vibration signal collector to collect the vibration signal of the 10kV line switch; ③The vibration signal is filtered by the signal processing module to filter out the small interference signal, and the 10kV line action is retained Intensity vibration signal; use the amplification module to limit the voltage value generated by the vibration signal within the effective range; use the signal delay mod...

Abstract

The invention relates to a 10kV line switch action indicating method and a 10kV line switch action indicating instrument, and belongs to the technical field of power supply equipment. According to thetechnical scheme, a vibration signal collector collects a 10kV line switch vibration signal; a small interference signal of the vibration signal is filtered out through a signal processing module, and a vibration signal with the action intensity of a 10kV line is reserved; a voltage value generated by the vibration signal is limited within an effective range by an amplification module; and a signal delay module delays an amplified pulse signal, so that a DTU can collect the pulse signal. According to the invention, effective alarm can be realized, passive response is changed into active response, the power transmission recovery time is shortened, the power supply reliability is improved, the power supply service quality is improved, and real-time control of fault power failure is realized.

Description

technical field [0001] The invention relates to a 10kV line switch action indicating method and a 10kV line switch action indicator, belonging to the technical field of power supply equipment. Background technique [0002] At present, the 10kV distribution network line realizes the interconnection, mutual belt and segmental control by using the switch to complete. In order to reduce the users and time affected by power outages, increase the number of section switches as much as possible when conditions permit. According to statistics, there are about 600 section switches in Qian'an area, which is a large number, and most of these switches are ordinary. Vacuum switch. This switch does not have an alarm function when the line fails and trips, and the power supply personnel can only respond passively, that is, they often rely on the user to call to inquire about the power outage; if all are replaced with intelligent switches, the equipment cost alone will be as high as several...
