Background technology
At present, existing generator water resistance load test switch board resistor fluid cooling device, cooling cooling resistor fluid is to adopt heat-exchangers of the plate type string heat radiation tower mode, just high temperature resistance liquid is evacuated to heat-exchangers of the plate type by the resistor fluid ebullator, carry out " high temperature resistance liquid---low-temperature cooling water " heat interchange, low-temperature resistance liquid turns back in the resistor fluid case; High-temperature cooling water is delivered to the heat radiation tower and is carried out " high-temperature cooling water---air " heat interchange, and low-temperature cooling water is pumped to heat-exchangers of the plate type by cool cycles and uses as chilled water.The weak point of this existing resistor fluid cooling device is that investment is big, occupied ground is big, make, transport, install difficulty, use has been subjected to limitation, need the chilled water water source simultaneously, and the necessary pure no-sundries of chilled water, otherwise heat-exchangers of the plate type easily stops up, the resistor fluid cooling effect is not good, hinders the normal operation of water resistance load.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation at above-mentioned weak point exactly, not other occupied ground, do not use chilled water, invest little, move convenient, flexible, the generator water resistance load test switch board resistor fluid cooling device of resistor fluid good cooling results, particularly a kind of middle low power generator water resistance load test switch board resistor fluid cooling device that is applicable to.
Technical solution of the present utility model is: a kind of generator water resistance load test switch board resistor fluid cooling device, be installed in the water resistance load test switch board, cooling fan, air-cooled heat exchanger, heat radiation exhaust duct sequential machine connect in the device, it is characterized in that: air-cooled heat exchanger is immersed in the resistor fluid, and air-cooled heat exchanger is adopted in the cooling cooling of resistor fluid.
Air-cooled heat exchanger system described in the technical solution of the present utility model is immersed in the shell and tube air-cooled heat exchanger in the resistor fluid, the resistor fluid filling is outside the tubulation pipe, cooling fan is blown in tubulation, high temperature resistance liquid that tubulation is outer and the cold wind in the tubulation carry out heat exchange, resistor fluid cools, the hot blast emptying after heat exchange heats up.The purpose that resistor fluid must cool is, water resistance loads on the heat that consumed power produced in the operational process raises the resistor fluid temperature, keep the interior resistor fluid temperature rise of resistor fluid case in certain limit, can make the resistor fluid resistance basicly stable, can guarantee that particularly the water resistance load can not cause electrical insulation properties to descend because of the vaporization of high temperature resistance liquid and influence its safe operation.
The beneficial effects of the utility model are: generator water resistance load test switch board is installed in the water resistance load test switch board with the resistor fluid cooling device, compact conformation, not other occupied ground; The resistor fluid cooling type of cooling adopts air-cooled heat exchanger, and air-cooled heat exchanger places the resistor fluid of resistor fluid case, can save the circulation of resistor fluid ebullator, cooling water circulating pump, heat radiation tower and resistor fluid, chilled water and cut down door with pipeline, and not use chilled water, investment is much smaller; Install simple, easy to operate, resistor fluid good cooling results, the required resistor fluid requirement that cools in the time of can satisfying the water resistance load and normally move.
