Usually the use of power is very important. Outdoor DC power supply is an important part of the power system that provides uninterruptible power supply and emergency lighting power for a number of important conventional load, relay protection, automatic devices and sports communications devices. When DC system touch ground little, It will not generate short-circuit current, so you can continue to use it. However, you must promptly find the touch point and eliminate the fault as soon as possible, or when another ground occurs, it may cause misunderstanding or refusal action of signal devices, power protection and automatic device, which may lead to short-circuit of the DC power.
Outdoor power equipment DC power supply can form a constant current device in the circuit, such as dry batteries, batteries, DC generators, etc. DC power supply has been widely used in all walks of life. There are even applications in the field of agriculture. DC power supply can be used in the technology of dust electrostatic spraying insecticide, agricultural materials electrostatic spraying package of the agricultural environment electrostatic and processing of agricultural products, electrostatic flocking, static electricity sterilization, agricultural seed electrostatic treatment, etc.
To use the outdoor DC power supply, the potential difference between the two poles should maintain constant. The process that positive charge flows from the positive electrode to the negative electrode in the external circuit and the direction of particle electric field force maintains from negative electrode to positive electrode in internal power can not rely on electrostatic power, but a context to achieve the opposite direction of the non-static power. Therefore, the power supply is a non-electrostatic force device which can convert non-electric energy into positive and negative electrodes through non-electrostatic work.
