Problems solved by technology

However, when working on complex electrical equipment (complex line sections), or where there may be crossover or intermittent live equipment, when an electrical connection part is overhauled, tested by multiple disciplines, and multiple personnel work, especially adjacent live lines When the tower is very close and the construction distance is long and it is easy to climb by mistake, the person in charge of the work cannot control all the movements of the forbidden block

Embodiment Construction

[0016] As shown in the figure, the method of preventing mistaken entry into the electrified interval in the electric power engineering operation, the steps are as follows:

[0017] 1. According to the on-site conditions, temporarily install and install detectors in the space corresponding to the forbidden barriers that need to monitor the entry of human body. The detectors are two and installed on the top of the detection and monitoring space to achieve all-round detection. Each detector can The detection and monitoring range is 0-7 meters, and the angle is within the range of 120°; the alarm is carried by the person in charge of the work or left in the main control room;

[0018] 2. Start the detector, once someone enters the space where the human body is monitored, the detector will sense and confirm that there is a human body within 2 seconds; when the detector confirms that someone has entered, it will automatically trigger the wireless signal transmitter to emit a wireless...

Abstract

A method for preventing mistaken entrance into a charged interval in an electric power engineering operation can timely remind and stop an operator mistakenly entering a barrier and prevent the mistaken entrance into the charged interval (a charged tower) to result in personal accidents. The method comprises the steps that a detector is temporarily arranged in a space required to monitor human body entrance in a prohibition barrier according to a field situation; an alarm is carried by a working principal or left in a master control room; the detector is started; once someone enters the space monitoring the human body entrance, the detector induces to confirm that a human body enters; after the detector confirms that someone enters, a wireless signal transmitter is automatically triggered to transmit a wireless alarm signal; the alarm automatically triggers acousto-optic alarm and prompts the number of the detector giving the alarm; and the working principal or a person in the master control room obtains the number of the detector giving the alarm after finding the alarm given by the alarm, immediately goes to a position where a person mistakenly enters the prohibition barrier according to the number of the detector giving the alarm, and orders the mistakenly entering person to leave the prohibition barrier.

Description

technical field [0001] The invention relates to a method for preventing mistaken entry into a charged interval in electric power engineering operations. Background technique [0002] There are line operations and substation operations in electric power engineering, and the person in charge of the work is the organization manager and safety person in charge of the on-site construction. Always be at the key work site, carefully monitor the work behavior of the staff in the work class, and promptly correct any behavior that may endanger the safety of the person, the power grid, and the equipment. However, when working on complex electrical equipment (complex line sections), or where there may be crossover or intermittent live equipment, when an electrical connection part is overhauled, tested by multiple disciplines, and multiple personnel work, especially adjacent live lines When the tower is very close and the construction distance is long and it is easy to climb by mistake,...
