Description
Technical field
The present invention relates to Mine-used I. S power supplys, more particularly, to the Mine-used I. S power supply for having elimination spark energy.
Background technique
According to the requirement of national standard GB3836, essence all must satisfy to the power supply for the electrical equipment that underground coal mine uses
Safety type power requirement.With the intelligentized fast development of Internet of Things, many downhole coal mine equipment both increase intelligent automatic
The electrical equipment of control, thus it is increasing to the output power demand of intrinsically safe power supply.It is currently used for underground coal mine
Intrinsically safe power supply all uses output to reduce electrical equipment with the spark energy for carrying with occurring under short-circuit conditions
The mode of series resistor limits supply current, to consume spark energy；It is this that energy is consumed by way of series resistor
Measure it is excessive so that intrinsically safe power supply carrying load ability decline, limit the output general power of intrinsically safe power supply.
Summary of the invention
It is an object of that present invention to provide a kind of Mine-used I. S power supplys for having and eliminating spark energy.
To achieve the above object, the present invention takes following technical proposals:
It is of the present invention to have the Mine-used I. S power supply for eliminating spark energy, including be arranged in the intracorporal essential safety of explosion-proof shell
Type power supply body and linear choke coil, the first inductance of the anode and the linear choke coil of the intrinsically safe power supply ontology
The other end of the connection of the one end coil L1, the first inductance coil L1 connects positive pole output terminal, in the first inductance coil
The both ends of L1 are parallel with the anode and the positive pole output end of the first damper diode D1, the first damper diode D1
Son connects and cathode is connect with the anode of intrinsically safe power supply ontology；The cathode of intrinsically safe power supply ontology and linear chokes
Second one end inductance coil L2 connection of circle, the other end of the second inductance coil L2 connect the power cathode output end
Son, the both ends of the second inductance coil L2 be parallel with the second damper diode D2, the second damper diode D2 anode with
The cathode of intrinsically safe power supply ontology connects and cathode is connect with power cathode output terminal.
The invention has the advantages that concatenating linear choke inductance in the output circuit of existing intrinsically safe power supply ontology
And damper diode, thus be effectively reduced with carry and short-circuit conditions under burst current, reach reduce spark energy, guarantee mine
Under the premise of being powered with intrinsic safety type power safety, electric current is limited using inductance, consumed energy specific resistance is small, improves mine
With the output load capacity of intrinsic safety type power supply.
