Abstract

The invention relates to mining electrical engineering. The goal is to increase device reliability. It contains a protection-free shell 1 with the first 2 and second 3 inputs, a network stabilized DC power supply 4, consisting of a transformer, a format 5 with a network 6, a first 7 and a second 8 secondary windings of the rectifier 9, a smoothing filter 10, a stabilizer 11, rectifier 12 and cooled element 13. The device has a metal plate, the first 15 and the second 16 sections of the cascade battery of solid-state microcoolers, located coaxially, the load 17 and the spark-proof device 18. The stabilizer 11 feeds the load 17 stabilized m voltage. The current through the element 13 and the load 17 passes through the first section 15 of the cascade battery of solid-state microcoolers. In this case, due to the Peltier effect, one of the surfaces of the batteries is heated, and the other is cooled. Heat is absorbed on the surface facing the cooled element 13 and heat is generated on the opposite surface. Heat is released through the wall wall of sheath 1. The greater the current consumption from source 4, the stronger the surface of the first battery section 15 cools. At the same time, the voltage from the second secondary winding 8 through the rectifier 12 and the spark-proof device 18 is supplied to the second section 16 of the battery, which causes the forced removal of heat from the explosion-proof casing 1, 1 or less.

(54) STABILIZED POWER SUPPLY IN EXPLOSIVE-SAFETY SHELL (57) The invention relates to mining electrical engineering. The goal is to increase the reliability of the device. It contains an explosion-proof casing 1 with the first 2 and second 3 inputs, a stabilized DC power supply 4, consisting of a transformer 5 with a network 6, the first 7 and second 8 secondary windings of a rectifier 9, a smoothing filter 10, a stabilizer 11, a rectifier 12 and cooled element 13. The device has a metal plate 14 _{} the} first 15 and second 16 sections of the cascade solid-state micro-cooler battery, located coaxially, the load 17 and the spark protection device 18. The stabilizer 11 supplies the load 17 with a stabilized voltage living. The current passing through the element 13 and the load 17 also flows through the first section 15 of the cascade solid-state micro-cooler battery. At the same time, due to the Peltier effect, one of the surfaces of the batteries is heated, and the other is cooled. Heat is absorbed on the surface facing the cooled element 13 and heat is released on the opposite surface. Heat is transferred through the metal wall of the shell 1. The greater the current consumption from the source 4, the more the surface of the first section 15 of the battery cools. Simultaneously, the voltage from the second secondary winding 8 through the rectifier 12 and the spark protection device 18 is supplied to the second section 16 of the battery, which causes the forced removal of heat from the flameproof enclosure 1. 1 ill.

Moreover, the greater the consumption from the stabilized mains supply 4, the more the surface of the first section 15 of the cascade battery cools. At the same time, the voltage from the second secondary winding 8 through rectifier Ϊ2 and spark arrester 18 is supplied to the second section 16 of the cascade solid-state microcooler battery, which causes the cooling of its surface facing the explosion-proof shell and the forced removal of heat from it. Heat is removed from the opposite surface of the second section 1.6 of the cascade solid-state micro-cooler battery due to contact with the production air.

In this significant role. there is convection by the movement of a jet of air to produce. The amount of heat removed increases with increasing voltage, which is absolutely necessary, since in this case the amount of heat generated on the cooled element 13 increases.

In this case, the current flowing through the cooled element 13 and. load 17 also flows through the first section 15 of the cascade solid-state micro-arrays of solid-state batteries,

The flow of current through a cascade battery of solid-state micro-coolers causes cooling of one of its surfaces and heating of the opposite (this phenomenon is based on the Peltier effect). ”
