Problems solved by technology

The disadvantage is: due to the increase of the resistance, the efficiency of the power supply is reduced, which is not conducive to the realization of high power
Disadvantages are: lower conversion efficiency, and multiple measures must be taken to improve reliability
③Adopt the frequency increase method to increase the frequency and reduce the output filter capacitance of the power supply, thereby reducing the spark energy of output short-circuit discharge, but the circuit structure and control method are more complicated
In addition, in order to prevent explosion, the currently used power supply has a flameproof casing outside the body of the power supply, which not only increases the weight of the equipment, but also has poor heat dissipation, and also increases the cost of the equipment.
According to statistics, there are currently about 26,000 coal mines of various types in China, including more than 3,000 large and medium-sized coal mines. The key problem is that the monitoring and monitoring system is not perfect, and there are many hidden dangers, so equipment improvement is imminent

Abstract

The invention relates to a capacity short current strike energy releaser which is mainly formed by an electric screen circuit 1, a short circuit detecting circuit 2 and a capacity energy releasing circuit 3. The capacity energy releasing circuit is formed by a driving circuit 3-1 and an energy releasing circuit 3-2, or the energy releasing circuit 3-1. The capacity short current strike energy releaser is mainly used in the environment monitor and monitor control system of mine, petrifaction and so on.

Description

technical field [0001] The invention belongs to an electronic product, which is mainly used in dangerous environments such as coal mines and petrochemicals, and is precisely a capacitor short-circuit spark energy releaser in power supply equipment or other electronic products. Background technique [0002] A capacitor is an energy storage element, and its stored energy is proportional to the square of its voltage. If a capacitive element with a certain voltage is short-circuited, a large spark energy will be generated in a very short time. However, if a circuit or system with capacitive components, such as a DC power supply, is used in a dangerous environment with flammable and explosive gases, when the energy stored in the capacitor is large enough, the spark energy generated by the short circuit will detonate the dangerous environment. gases or their mixtures. Therefore, for the safety of circuits or systems and hazardous environments, the relevant standards have made st...
