2.Acceptance record
After the installation and testing, the detailed acceptance test of the equipment and the experiment are as follows:
1). Operation steps and methods: carry out wave full wave and steep wave experiments, and the experimental results are recorded.
2). Lightning full wave: the use of wave head resistance value of 50 Ω (no sense resistance), wave tail resistance value is 180 Ω (no sense resistance). The waveforms generated by the attached experiments are as follows:
a. Full wave positive polarity of lightning:
b.Full wave negative polarity of lightning:
The steep wave head has a resistance value of 20 Ω(no sense resistance) and a resistance of 180 Ω with a tail resistance value. The experimental waveforms are as follows:
3). Operation result: equipment running with test sample is running normally.
a.Operation procedure and method: to increase the lightning withstand voltage required by the equipment or the sample, and the steep wave withstand voltage. And recorded its experimental waveform.
b.Operation result: the equipment is running normally and the waveform produced by the experiment conforms to the national standard.
3. Acceptance conclusion
Through the tests and experiments, it is proved that the full wave and steep wave waveforms produced by the 900 KV/27KJ full automatic impulse voltage generator of this equipment can meet the requirements of the national standard. Technical parameters and quantity of each device, including weak damping capacitance divider, high response resistor divider and sharpening device are consistent with the contract, after installation and commissioning and good performance, normal operation, and technical parameters of the waveform are in line with the requirements of the relevant experiments, acceptance.
(Subsidiary description: The equipment shall be dustproof, damp proof and regularly energized to prevent the aging of the circuit boards and components. The equipment should be powered by a single power supply in the course of experiment, and the ground wire should be grounded separately. It should not be carried out simultaneously with other large capacity high-voltage experimental equipment, such as power frequency test)
