The importance of household solar power plant fire

Household solar power station fire is very important, electrical fire generally refers to as the electrical wiring, electrical equipment, instruments, and distribution equipment malfunction release of heat energy; Such as high temperature, electric arc and spark, and not the obstacle of energy released; Such as electric appliance

fire prevention is very important in domestic solar power plants. Electrical fires, often referred to as due to the circuit, electrical equipment, appliances and power supply equipment failure and release of heat energy. Such as high temperature, electric arc, spark and barrier-free release the energy; Electric appliances, for example, hot surface can be lit under the condition of burning the body or other flammable materials, including the fire caused by lightning and static electricity. The family of the main causes of electrical fire is as follows: first of all, on the wire; The second is about electrical equipment and appliances. Photovoltaic cells, however, China's photovoltaic power station is composed of photovoltaic panels, inverters, cables, etc, and most household photovoltaic power station are incorporated into the national grid, so its safe and deserve more attention. So I thought of an old problem: photovoltaic power station easy to cause fire? Conventional photovoltaic power station of all the equipment before delivery after rigorous testing. Especially the inverter and short circuit protection device of distribution box. Photovoltaic power station special cable also use flame retardant materials. Therefore, the probability of photovoltaic power station fire is much lower. However, we should not look down on important festivals. The house has been swept clean. Photovoltaic power station and other household appliances and circuit also need a thorough inspection and cleaning. Security is very important, after all, New Year holiday. A check 1, domestic solar power station. Component 1) Don't underestimate shelter, regardless of the size and location. If there is a small bunker, lead to 90% power loss, must promptly notify the installation personnel to adjust! 2) Whether the assembly surface covered with a lot of dust and gun fragments, bird droppings, such as dirt, should be cleaned in time, only with a soft cloth to clean, dry or wet. Recommended for cleaning in the morning or evening, so the light will not have too strong, the temperature of the component is low. 2. Support 1) Whether stents rust or curved; 2) Parts of fixed screw ( Stents and components, and the base) Whether is loose, rust or damage, if necessary, adjust or replace. 3. Cable (1) Photovoltaic power station cable should be used to withstand harsh environment of the special photovoltaic cable; 2) Components at the back of the cable arrangement is neat. Component junction box behind the current cable transmission, should hide in the bracket ( As shown in the figure below) 。 Otherwise, the wind and rain for a long time, and, it is easy to aging, can greatly shorten the service life. 3) Check all kinds of connectors and cable connection is unstable or naked. In this case, it is necessary to timely treatment, avoid water due to wet weather or rain and snow weather cause fire. 4, inverter, power distribution boxes, instrumentation, etc. 1) Check all wire connector is loose in the inverter. If there is a virtual connection, it may cause fire, immediately contact the installation personnel for maintenance. 2) Check the circuit breaker of distribution box is working correctly. 3) Check whether pv electricity meter (default in Bright yellow light), 。 Balance, if any, should be timely to the power grid company pay, lest affect normal operation of power station, delay in income.
