Isolation protection.
All insulated protective equipment can be divided into primary and secondary. Applying the basic insulating means, a person can touch live parts under tension. Therefore, isolation of these remedies must reliably withstand voltage electrical systems.
Additional protective measures are used in conjunction with the basic as well as serve as a measure of protection against the voltage step, in installations with voltage up to and above 1000, there are various protective measures.
The main tools in electrical insulation over 1000 include: insulating the bar;
insulating and current clamp, voltage indicators;
Insulating apparatus for maintenance work (insulating ladders, platforms). Additional remedies include: insulating gloves, insulating boots, insulating rubber mats, and insulated stand.
The main tools in electrical insulating d 1000 include:
insulating gloves, tools with insulating handles, pointers voltage. Additional features include: insulating rubber mats, insulated stand.
Insulating rods are used to enable or disable knives isolators, to overlay the temporary grounding, testing the absence or presence strain. Rods have three parts - a working, and an insulating handle, separated by a restrictive ring. Insulating clamps are used to change the fuse tube to install rubber pads on the knife.
Design mites are different.
Tool handles are made of insulating material and have a length of 10 cm; they lug to avoid slipping off the hands and touch the metal parts of the instrument. Before using the tool must check the condition of insulating handles. If there are cracks in them or use the tool chipping is prohibited.
Dielectric gloves and mats made of rubber of special stamps, which has a high dielectric strength.
Before starting work gloves checked for leaks. Dielectric mats spread out in front of electrical installations located in areas with high-risk and highly dangerous. In damp and dusty places dielectric properties of the mats are sharply reduced, and they cannot provide reliable isolation of man from the floor. In such cases, instead of applying insulating mats coasters. Bce protective insulating means kept indoors and protected from moisture, dust and mechanical damage. All protective equipment must be protected from exposure to chemicals and heat rays to heat, otherwise may damage rubber.
Requires periodic inspection of the protective means technical staff. |
