Rubber insulation mats are indispensable protective products in switchboard rooms, power plants, substations, switchboards, diesel engine rooms of gas stations and other places. However, the rubber insulating pads used at some gas stations are too narrow and placed in remote locations. There are even bulges and oil stains in some parts. Users check the electrical distribution cabinets in the electrical distribution room and open the electrical distribution board. the work room. The feet do not completely rest on the insulating rubber pad, causing the insulating rubber pad that is supposed to play a protective role to completely become a decoration. Once the danger occurs, it will directly threaten the safety of users. We can't treat our life like child's play! ! ! !
The function of the insulating rubber pad is to insulate from the ground to prevent the user from forming a closed circuit between the human body and the ground when contacting the live wire, thereby protecting safety personal information of the user. So, what standards must qualified rubber insulating pads meet? According to the currently applicable national standards for rubber insulating pads "DL/T 853-2004 Insulating Pads for Live Work" and "Safe Working Procedures for the Electrical Industry", electrical appliances such as substations, power plants, distribution rooms, distribution panels, gas stations, diesel engine rooms, etc. In part, the installation of rubber insulating pads should meet the following requirements:
The length and width should not be less than 800mm, and the thickness should be determined according toof the specific voltage and cannot be too low. For switchgear room voltages of 35 kV, 10-12 mm thick insulating rubber pads should be selected, for voltages of 10 kv, 8 mm thick insulating rubber pads should be selected, and for low voltages below 500V, 5mm thick insulating rubber pads should be selected. According to the "gas station operator skills assessment test question set", the insulating rubber pad of the gas station should reach a high voltage of 10kV, and an insulating rubber pad of 8mm thickness is appropriate!
Of course, when choosing a rubber insulating pad, you can not only look at the thickness, the main thing is the quality. Even if the thickness reaches a lower quality, it will have no effect! High quality insulating rubber pads must meetconform to the following standards:
The upper and lower surfaces shall be smooth and free from holes, cracks, local bulges, cuts, conductive foreign objects, creases, gaps, uneven undulations, and casting marks. Uniformity and damage to smooth surface defects to avoid lowering voltage resistance standards and shortening breakdown time.
In daily use, you should also pay attention to the maintenance of the rubber insulating pad. It cannot be used in a humid environment (it will destroy its insulation). It is prohibited to come into contact with oil. , acid, alkali or other harmful substances in order to avoid being corroded and failing to achieve the appropriate insulation effect. Avoid close contact with heat sources, avoid direct sunlight (direct sunlight will accelerate the aging of the insulation pad), and avoid collision or radiation.res with sharp objects (to avoid cracking), otherwise it may lose its proper insulating effect. It must be stored in a dry and ventilated environment, at least 1 meter from heat sources.
Normally, you need to pay more attention to the maintenance and installation of rubber insulating pads. When operating distribution cabinets, distribution boards and diesel generators, you must ensure that both feet rest on the rubber insulating pads.
Insulating rubber pads are also called insulating blankets, insulating mats, insulating rubber sheets, insulating rubber sheets, insulating rubber mats, insulating floor glue, insulating rubber, insulating gaskets, etc., and have high volume resistivity and electrical breakdown resistant rubber pad. Insulating materials for counters or floors used in workplaces such as dielectricity distribution.
Insulating rubber is widely used in substations, power plants, switchboard rooms, test rooms and field operations. It is mainly made of rubber insulating materials. There should be no harmful irregularities on the top and bottom surfaces. of the insulating pad. Harmful irregularities refer to any of the following characteristics, i.e. defects that destroy uniformity and damage the smooth contour of the surface, such as small holes, cracks, local ridges, cuts, inclusion of conductive foreign bodies, folds, voids, concave. and convex ripples and pour marks, etc. Harmless irregularities are surface irregularities formed during the production process.
Rubber insulation tile (also called: rubber insulation, insulation table mat, rubber insulation mat) is theAbbreviation of rubber insulating tile: Rubber insulating tile is a rubber tile with large volume resistivity and resistance to electrical breakdown. Made of non-polar rubber with excellent insulation properties such as NR, SBR and IIR. Insulating materials for counters or floors used in workplaces such as electricity distribution.
