Audited Supplier Anti-interference transmission line insulation resistance tester
Functional characteristics
KD7688 anti-interference line insulation resistance test device can effectively reduce the power frequency induction voltage, restrain the high frequency voltage, so that the DC high voltage of insulation resistance test is loaded on the tested product through the device, so as to ensure the authenticity of insulation test. At the same time, the anti-interference auxiliary device can also measure the induced electricity through the filter network, and play a high-voltage isolation role, and connect the high-voltage area with the instrument operating area
The anti-interference ability of the insulation resistance meter is not less than 1000 volts, with analog and digital dual display, and can automatically measure the insulation resistance, absorption ratio and polarization index.
Strong anti-interference ability
Strong anti-interference auxiliary device KD7688, the auxiliary device adopts special anti-interference technology, can effectively reduce the induced voltage, so as to ensure the authenticity and effectiveness of insulation test. The device can resist induction voltage up to 30kV. Strong anti-interference insulation resistance meter KD7688, a single insulation resistance meter anti-interference ability of up to thousands of volts. Can automatically measure insulation resistance, absorption ratio and polarization index. Conventional measurement has 4 rated voltage levels, 0.5kV/1kV/2.5kV/5kV. The test voltage of the external high-voltage auxiliary device is 5kV. Light weight strong anti-interference auxiliary device KD7688 single equipment weight is 7KG, strong anti-interference insulation resistance meter KD7688 single equipment weight is 8KG. Equipped with a towed instrument box, easy to carry and practical.
High security
Strong anti-interference insulation test equipment is composed of anti-interference auxiliary device and insulation resistance meter, space will have a high risk of induction and personnel operation instrument separated, the operation of the first use of anti-interference auxiliary device to measure the size of induction, in the case of can continue to measure insulation resistance, so as to avoid the strong induction of direct harm to equipment and personnel. In addition, the test power supply is directly from the insulation resistance meter, and no external high-power and high-voltage equipment is required, which greatly reduces the workload of field operation and other risks, and makes the insulation test safer in the case of strong interference.
Can effectively reduce the induction voltage, the overall inhibition capacity of more than 100 times.
The effect of the device on the short circuit current is small, and it can still be 5mA equivalent short circuit current after connecting the device.
Multi-section design, it is easy to upgrade and expand with higher levels of anti-interference.
Vertical use, high and low pressure effective separation, high safety.
