Embodiment Construction

[0026] Below in conjunction with embodiment the present invention will be further described.

[0027] A monitoring method for safety inspection and maintenance of primary equipment in a substation, comprising the following steps:

[0028] Step (1): Measure the distance between the staff and the bus by using the electrified interval calculation technology: first calculate the horizontal distance between the mobile phone and the staff, then calculate the height of the staff, subtract the height of the staff from the height of the bus to get the distance between the staff and the bus The actual distance will alarm when it is less than the safe distance; the distance between the measuring staff and the bus can be obtained by using the Pythagorean theorem;

[0029] Step (2): Use video speed measurement technology to measure the instantaneous speed of the vehicle passing by: the time change can be directly obtained through the fixed frame time of the video signal, and the time chang...

Abstract

The invention discloses a safe overhauling and monitoring method for substation primary equipment. The method comprises the steps of utilizing an electrified interval to compute the distance between technical measuring work staff and a bus; utilizing a video speed measuring technology to measure the instant speed of a passing vehicle; directly obtaining the time variable by the fixed frame interval time of video signals, indirectly computing the changing distance of the vehicle or people in the fixed frame interval by other methods, measuring the speed of the vehicle or people, and alarming when the speed exceeds the set value; and computing the safe distance between equipment and the vehicle as well as the people, wherein the principle for measuring the instant speed of the passing vehicle is that the speed is the ratio of distance and time. The safe overhauling and monitoring method for the substation primary equipment can be widely applied to the overhauling and monitoring field, thus effectively improving the occurrence of accidents of people electric shock and equipment damaging; and the realizing of the overhauling and monitoring method can directly improve the safe overhauling level of electric enterprises.

Description

technical field [0001] The invention relates to a monitoring method for safety maintenance of primary equipment in a substation, which belongs to the technical field of electric power. Background technique [0002] At present, the more common proximity alarm devices of the State Grid Corporation of China are mainly watch-type proximity alarms and safety helmets equipped with proximity alarms. The single function is only limited to near electric alarm, and there is no speed alarm function when vehicles and people approach the primary equipment. Future alarms will be characterized by flexibility, reliability, versatility and low cost. In the past, power transmission and distribution maintenance operations used shielded clothing, and used overhead insulated bucket trucks or ground potential indirect operations. According to the safety distance determined by the regulations, the site environment and the structural conditions of electrical equipment for live work in power distr...
