Technical field
The utility model relates to slip ring technical field of performance test more particularly to a kind of high-power slip ring performance test dresses
It sets.
Background technique
When high-power slip ring works, needing to bear high voltage and high current, (the high-power slip ring more than 200kW is mostly
The transmission voltage of kV rank, and with the increase of slip ring power, voltage, electric current also can and then increase), this is just to high-power slip ring
Insulation performance and its each loop electrical performance requirements between internal each loop is very high, very must so being tested for the property
It wants.
For the place of high-voltage fence inadequate resource, it is difficult to meet the MW gradation electricity demanding of high-power slip ring performance test,
Although can realize the high voltage requirements of high-power slip ring performance test, such as CN using a series of instrument and equipments such as transformers
205669496U " test device of high-power electric pump group ", but since general load is all difficult to bear high current, unless adopting
It is together in parallel to shunt with many loads and be used, bearing power required for causing is excessive, also just significantly draws high in this way
The complexity and cost of experiment, so the test condition of high current hardly results in satisfaction, when being tested also mostly using
Low current, such as CN105974247A " test macro and method of conducting slip ring ".Even for the ground of high-voltage fence resource abundance
Side, is able to satisfy MW grades of test electrical power distribution demand, but also needs enough loads for consuming the electric energy from power supply, if
It is tested using existing power transmission network, risk is too high, and it is careless slightly large-area circuits to be caused to damage, or even cause fire
Calamity；Such as according to other loads, since power is too big, then cost is excessively high, and risk is also very big.Current high-power slip ring performance
Test method all can not carry out the high-power slip ring performance test under the conditions of high voltage and high current simultaneously.
For small and medium-sized manufacturing enterprises, to meet MW grades of electricity demanding of matching and even be not easy, still more also want progressive
