Abstract
A3300V mining flame-proof frequency converter water cooling device comprises an inner water channel, an outer water channel and a water-water heat exchanger, wherein the two water channels exchange heat through the water-water heat exchanger to take away the heat of the inner water channel. The water cooling device of the 3300V mining explosion-proof frequency converter is reasonable in structure collocation, well solves the heat dissipation problem of the mining high-voltage explosion-proof frequency converter, and does not damage the explosion-proof structure of equipment.
Description
Technical field
The present invention relates to a kind of mining high-voltage frequency converter, specifically, is a kind of 3300V mine explosion-suppression frequency converter water-cooling apparatus.
Background technology
Frequency converter belongs to technology maturation type product on ground, but because the colliery subsurface environment is abominable, and the existence of factors such as damp such as methane and coal dust is arranged, and can not get effective solution because of problems such as explosion-proof heat radiations eventually, and the use of frequency converter under coal mine is restricted.Because the particularity of coal mine working environment makes the development of frequency converter receive very big restriction, the RHVC of 3300V electric pressure especially, because explosion separation structure is big, heat dispersion is not good, does not almost have especially.
Summary of the invention
The present invention is directed to the long-term insoluble heat dissipation problem of mining high-voltage frequency converter, designed a kind of mine explosion-suppression frequency converter water-cooling apparatus.
3300V mine explosion-suppression frequency converter water-cooling apparatus of the present invention comprises Nei Shui water route, Wai Shui water route, water-water heat exchanger, and two cover water routes are taken away the heat in Nei Shui water route through the water-water heat exchanger heat-shift.
Preferably, the Nei Shui water route is inner deionized water cooling circuit.
Preferably, there is the buffer container that can avoid water impact in the cooling system inside, Nei Shui water route.
3300V mine explosion-suppression frequency converter water-cooling apparatus of the present invention, the rational structure collocation has well solved the heat dissipation problem of mining high-voltage explosion-proof frequency converter, and has not destroyed the blast resistance construction of equipment.
Description of drawings
Accompanying drawing 1 is the hydrographic chart of 3300V mine explosion-suppression frequency converter water-cooling apparatus of the present invention.
Embodiment
3300V mine explosion-suppression frequency converter water-cooling apparatus of the present invention, as shown in Figure 1, comprise Nei Shui water route, Wai Shui water route, water-water heat exchanger E1, two cover water routes are taken away the heat in Nei Shui water route through water-water heat exchanger E1 heat-shift.Wherein, the cooling water in Nei Shui water route is a deionized water, and deionized water is non-conductive, and the main heating device of the frequency converter of need flowing through: IGCT, reactor and water-cooled resistance etc., the cooling water in Wai Shui water route is an external refrigeration water.
The left-half of water-water heat exchanger E1 is the Nei Shui water route; In first the use, need distilled water be injected the water route through water filling port, C1 is the deionization jar; Main effect is when system's needs are deionized; Drop to the ion degree of system minimum, C2 is the buffer container of cooling system, has avoided the water impact in the cooling system.
After the system start-up; Under the effect of water pump M11 and M12,, adjust the discharge of inner deionized water according to the real time data of pressure sensor B11, temperature sensor B13, conductivity sensor B12 in good time; Through water-water heat exchanger E1, take away the heat in Nei Shui water route.
For satisfying the requirement of explosion proof of equipment, the Wai Shui water route is connected with water-water heat exchanger E1 through stainless steel flexible hose.
Claims (3)
1. a 3300V mine explosion-suppression frequency converter water-cooling apparatus comprises Nei Shui water route, Wai Shui water route, water-water heat exchanger, it is characterized in that, two cover water routes are taken away the heat in Nei Shui water route through the water-water heat exchanger heat-shift.
2. 3300V mine explosion-suppression frequency converter water-cooling apparatus according to claim 1 is characterized in that the Nei Shui water route is inner deionized water cooling circuit.
3. 3300V mine explosion-suppression frequency converter water-cooling apparatus according to claim 1 is characterized in that there is the buffer container that can avoid water impact in the cooling system inside, Nei Shui water route.
