To standardize the preventive testing of electrical safety tools and ensure their safety and reliability during use，It specifies the items, cycles, and requirements for preventive testing of various commonly used electrical safety tools, and provides corresponding testing methods to determine whether these tools meet the usage conditions and ensure the personal safety of workers.A power equipment testing company in Nanjing has purchased a batch of high-voltage testing equipment, mainly consisting of600KVComplete set of equipment for power frequency test transformer、7000A three-phase high current temperature rise test device, 1050KVComplete set of impulse voltage generator equipmentInsulated boots (gloves) voltage withstand test deviceWaiting for other testing equipment, instruments, and various test supports. Our company's technical personnel went to the customer's site for installation, debugging, and training. Our technicians patiently guided users on equipment operation methods and precautions, and users actively cooperated and familiarized themselves with operating the equipment.

Safety tools are divided into two categories: insulated safety tools and general protective safety tools.

Insulation safety tools are divided into basic insulation safety tools and auxiliary insulation safety tools.

Basic insulation safety tools refer to tools that can directly operate live equipment or come into contact with or may come into contact with live objects, such as capacitive testers, insulation rods, phase detectors, insulation covers, insulation partitions, etc. The difference between these tools and live work tools is that they are used for short-term contact with live objects or non-contact live objects during the working process. In this regulation, portable short-circuit grounding wires are also included in this category.

Auxiliary insulation safety tools refer to tools that have insulation strength that does not withstand the working voltage of equipment or lines, but are used to strengthen the security function of basic insulation safety tools, to prevent harm to operators from contact voltage, step voltage, leakage current arc, and cannot directly contact the live parts of high-voltage equipment with auxiliary insulation safety tools. Safety tools belonging to this category include insulated gloves, insulated boots, insulated rubber pads, etc.

General protective equipment refers to tools used to protect workers from accidents, such as safety belts, helmets, etc. In this regulation, foot buckles, lifting plates, ladders, etc. used for climbing are also included in the category of personnel. Conductive shoes also fall under the category of humans.

Preventive testing is a method and means of testing, detecting, and diagnosing electrical safety tools to prevent accidents from occurring due to changes in their performance or potential hazards during use.

High voltage to ground voltage250V以上。

Low voltage to ground voltage250V and below.

Capacitive voltage tester is a device that detects the current flowing through the stray capacitance of the voltage tester to the ground, and checks whether the equipment and circuit are live.

Portable short-circuit grounding wire is a temporary grounding device used to prevent equipment and lines from suddenly coming into contact, eliminate induced voltage, and discharge remaining charges.

Personal protective grounding wire is mainly used as a personal grounding device to prevent induced voltage hazards.

Insulated rods are insulation tools used for short-term operation of live equipment, such as connecting or disconnecting high-voltage isolating switches, dropping fuses, etc.

Nuclear phase detector is a device used to detect whether the equipment to be connected and the electrical circuit are phase aligned.

An insulation cover is made of insulating material and is used as a protective cover to shield live or non live conductors.

A heavy insulated partition is an insulating flat plate used to isolate live parts and restrict the movement range of workers.

The insulation rubber pad strengthens the ground insulation of the staff and is made of a rubber plate made of special rubber.

Insulated boots are made of special rubber and are used to insulate the human body from the ground.

Insulated gloves are gloves made of special rubber that serve as electrical insulation.

Conductive shoes are made of special conductive rubberShoes used to prevent static induced voltage during non live operations on 220~500kV live towers and 330~500kV live equipment areas.

Personal protective equipment for preventing falls and injuries during high-altitude operations using seat belts.

A helmet that provides protection against external force injuries to the human head.

A tool for climbing electric poles made of steel or alloy materials with ankle buckles.

The lifting board is a tool for climbing electric poles consisting of a foot pedal and a hanging rope.

bambooA ladder is a tool made of wood or bamboo for high-altitude operations.
