Description
Technical Field
The invention belongs to the technical field of power systems, and relates to an electrified installation device and an electrified installation method for an arrester for an overhead power distribution line.
Background
The overhead distribution line of the power grid system is very easy to be struck by lightning to cause power accidents, so that the installation of the lightning arrester on the overhead distribution line is a common effective protection measure. When lightning strikes, instantaneous high-voltage current on the overhead distribution line flows through the lightning arrester and is led into the ground, so that the insulator is protected from being broken down. Generally, an insulator is vertically installed between a high-voltage line and a pole cross arm, an upper end of the insulator is connected with an overhead distribution line, and a lower end of the insulator is fixedly installed on the cross arm through a bolt and is grounded through a lead. At present, the lightning arrester with the current guiding ring is widely adopted in recent years due to the simple structure of the protective gap and the easy adjustment of the installation position. In the process of installing the lightning arrester by electric power personnel, the rod climbing short-distance operation is needed after the power failure of the circuit for protecting personal safety. Generally, power failure of a user caused by power failure installation affects industrial and agricultural production, power supply reliability and power supply service quality, power failure is not needed in live installation, normal use of the user is not affected, and the method has great significance for improving the power supply service quality and optimizing the operator environment of a power enterprise. Live-line work is divided into two types: the insulating glove operation method is characterized in that an operator directly wears an insulating protection tool to directly operate an insulator, once the insulator has a defect in insulating property, penetrating discharge is easy to occur to influence the safety of the operator and equipment, and the insulating rod operation method uses an insulating rod to indirectly operate outside a safety distance, so that the safety is high.
The current-guiding ring type lightning arrester and the insulator are approximately parallel and keep a certain transverse distance, the current-guiding ring type lightning arrester and the insulator are vertically installed between a high-voltage wire and a cross arm, a current-guiding ring at the upper end of the lightning arrester is sleeved on the periphery of the insulator, and a metal connecting plate at the lower end of the lightning arrester is installed between the insulator and the upper surface of the cross arm and is fixed on the cross arm together with the insulator through a bolt. In the process of installing the lightning arrester, electric power personnel firstly unscrew the bolt at the lower end of the insulator, then manually lift the insulator upwards, and simultaneously insert the connecting plate at the lower end of the lightning arrester between the insulator and the upper surface of the cross arm. Because the pressure leads to the insulator to the slope of overhead distribution line both sides direction under the overhead distribution line, insulator and cross arm clearance diminish, arrester lower extreme connecting plate can't insert, need upwards lift the insulator hard, then insert the arrester lower extreme connecting plate between insulator and the cross arm upper surface, the adjustment arrester keeps roughly at vertical position, screws the bolt of insulator lower extreme again at last. In the whole dismouting process, if an electric power personnel accomplishes above-mentioned dismouting very difficult, generally need two professional electric power personnel to mutually support to accomplish under the normal conditions, the operation process is loaded down with trivial details, wastes time and energy, and the dismouting is inefficient, leads to the circuit power off time overlength simultaneously. Therefore, an installation device for disassembling and assembling the lightning arrester by adopting an insulating rod operation method is urgently needed to solve the safety and the high efficiency of disassembling and assembling the lightning arrester.
