Technical field
The present invention relates to the technical indicator method of testing of ups system, particularly the impulse voltage endurance test method of test 220kV electric pressure and above transformer station ups system or the following transformer station of 220kV electric pressure ups system.
Background technology
The ac uninterrupted power supply that ups system provides should have higher voltage and frequency stability, and waveform distortion is little, and low noise and antijamming capability are strong.Therefore, need advance test to the ac uninterrupted power supply that ups system provides.The voltage endurance capability of each energized circuit is the assurance of ups system safety in the ups system.But still do not carry out the effective ways of the voltage endurance capability test of each energized circuit in the ups system at present.
Summary of the invention
The objective of the invention is to solve the problem that the voltage endurance capability of each energized circuit in the above-mentioned ups system can not effectively be tested, a kind of Validity Test method that is used for testing the voltage endurance capability of each energized circuit of ups system is provided.
Realize that the object of the invention technical scheme is: a kind of impulse voltage endurance test method comprises the steps:
A, load surge voltage at the test position, when rated operational voltage exchanges root-mean-square value or DC voltage when being less than or equal to 60V, surge voltage is 1kV; When rated operational voltage exchanged root-mean-square value or DC voltage and is less than or equal to 300V greater than 60V, surge voltage was 5kV;
B, surge voltage is added in other circuit and exposed conductive part the connect together ground connection of test beyond the position;
C, the test surge voltage of A regulation set by step add the surge voltage in short-term of 3 positive polaritys and 3 negative polarity lightning waves, are not less than 5s each off time;
D, judgement: if the equipment naked punctures and the flashover phenomenon in the process of the test, test back equipment does not have the disruptive discharge phenomenon, and then tested ups system is qualified.
Further, described test position be between each alive circuit non-electric-connecting in the energized circuit, between each independent alive circuit and ground or the metal framework, in the cabinet direct current bus-bar and WV disconnect every other when being connected branch road over the ground between.
Owing to adopted above-mentioned technical solution, solved the problem of the voltage endurance capability of each energized circuit in the test ups system fully, improve the efficient of the voltage endurance capability of each energized circuit in the test ups system significantly, thereby more effectively guaranteed the security performance of ups system.
