Description

High voltage electrostatic induction physical protection device

Technical field

This utility model provides a kind of electrical production utensil, especially a kind of safeguard protection utensil.

Background technology

Operation on the metal shell of the on-the-spot charging equipment of transformer station or framework, meeting with the influence of electrostatic induction voltage, particularly electric pressure often is 220kV and above equipment, under sunny exsiccant weather condition, the electrostatic induction phenomenon is very outstanding.Because the operating personnel wears the insulation rubber soled shoes or climbs on insulating ladder, has certain insulation between human body and the grounding body,, can produce electrostatic induction voltage when human body during near electrical body.The rated voltage of operational outfit is high more, and the operating personnel is near more from electrical body, and the electrostatic induction phenomenon is obvious more.For example, when on the device housings of 220kV, working, when hand-held metal tools contact arrangement shell or framework, electric arc that can generation 5～10mm between instrument and shell or framework, send simultaneously " " discharging sound.If during earth potential places such as careless contact arrangement shell of human body or framework, can form human body pulsed discharge over the ground, the burst sensation of pricking.This brings no small physiological effect and mental pressure can for the sampling personnel, not only influences normal running, even may cause the high-altitude to fall and fall accident.Generally speaking, the electric power safety rules require to wear the influence that electrostatic induction protective garment and conductive shoes prevent electrostatic induction voltage, if but above-mentioned safety device each several part bad connection may cause bigger electrostatic induction voltage.In addition, the work such as, activity duration weak point simple concerning job content, the transfer operation of many places, dress protective garment and conductive shoes and seem that some is loaded down with trivial details, feel very inconvenient, the operating personnel generally is difficult to adhere to use.Moreover except specializing in the troop of livewire work, general job department or unit can not be equipped with electrostatic induction protective garment and conductive shoes, and this can bring very big potential safety hazard.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of high voltage electrostatic induction physical protection device, to improve the safety of operation.

This utility model is achieved in that high voltage electrostatic induction physical protection device, its block of conductive material that is magnetic, and the magnetic conductive material block is electrically connected by the flexible circuit conductor and the conduction wrist collar.

Adopt the high voltage electrostatic induction physical protection device of said structure, can make things convenient for, eliminate effectively, reliably the influence of the electrostatic induction voltage that is produced when on the high voltage alive equipment shell, being engaged in activity, improved the safety of operation.And simple in structure, easy to use, production cost is low.

Description of drawings

Fig. 1 is the sketch map of this utility model structure.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.

As shown in drawings, the high voltage electrostatic induction physical protection device of this utility model, its block of conductive material 1 that is magnetic, the magnetic conductive material block is electrically connected by the flexible circuit conductor 2 and the conduction wrist collar 3.

During operation, the magnetic conductive material block is adsorbed on equipment metal shell or the framework by magnetic force, the wrist collar that will conduct electricity is enclosed within operator's wrist.Like this, the grounding body that the electrostatic charge that human body produces connects on the metal shell of the conduction wrist collar 3, flexible circuit conductor 2, magnetic conductive material block 1, charging equipment or framework is released into the earth, make human body and the earth keep idiostatic, avoided the generation of electrostatic induction phenomenon.In the work process, along with moving of operator's health, the magnetic conductive material block can slide at equipment metal shell or framework surface under pulling, makes human body be in protected state all the time.

The conduction wrist collar 3 can be made by materials such as silicone rubber conductive materials.

Claims (1)

1. high voltage electrostatic induction physical protection device is characterized in that, its block of conductive material (1) that is magnetic, and the magnetic conductive material block is electrically connected by the flexible circuit conductor (2) and the conduction wrist collar (3).
