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 danger occurs, it will directly threaten the user's life safety. We cannot treat our life as achild'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 determinede depending on 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 padstee shall meet 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.ns or scratches 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.
The car generator has water in it, what should I do?
Car manufacturers are equipped with a “Regular Car Maintenance Item Schedule” when each car leaves the factory. Maintenance items and cycles are usually formulated based on mileage traveled. The goal is to ensure the maintenance of the car. life thanks to regular maintenance. Optimal performance and service lifeextended life of the car.
Different manufacturers and models have different items and maintenance cycles. Therefore, you must carry out the maintenance and maintenance of your car in accordance with the on-board maintenance schedule.
For example, the image below shows the regular maintenance schedule for a certain car brand.
After water enters the engine, initial corrective measures should be taken according to the specific situation to avoid secondary damage to the vehicle and < /strong>discover the problem. The key is to minimize damage to the car.
After understanding the specific situation, if you find that water has entered the engine, you should remove the spark plug and artificially prevent the fuel supply system from starting and d ignition, so that the water in the engine can be drained successfully.
Once the inspectionction completed, use compressed air to treat the electrical connections inside the motor to prevent water from corroding them.
The parts to pay attention to are: the fuse box, the sensor socket and the body water accumulation area.
After cleaning, test drive the vehicle to ensure normal engine operation during use.
Repair Guide for Flooded Vehicles
1. Water passage is less than one third of the tire:
Water passage is divided into different degrees and levels. If your car only wades slightly in the water, less than a third of the tire size, then you don't have to worry too much. You can eliminate hidden dangers as long as you do a little inspection yourself.
Check if there is any trash attached to the chassis. Rain in Beijing is acidic and will corrode tire paint and rubber. To protect the painture and the tires of the car, the car should be cleaned in time. .
2. Water flooding up to one third of the tire:
If the water reaches more than one third of the tire, clean the sound insulation cotton in time.
Having the tire flooded more than a third of the way is the limit for repairing it after wading through water. Because if this limit is exceeded, water will penetrate upwards through the water-permeable holes in the vehicle floor, thereby wetting the sound insulation cotton inside the chassis.
