The arrester for the arrester is a high-voltage electric appliance used to monitor the discharge action of the arrester. Its structure consists of a non-linear resistor, an electromagnetic counter and some electronic components.

When the lightning arrester passes the lightning wave, the operating wave and the power frequency overvoltage, the powerful working current passes through the nonlinear resistance of the counter, and after DC conversion, the electromagnetic coil is discharged and the counter is sucked once to realize the device for measuring the number of times of the arrester .

JS-8 type discharge counter adopts ZnO resistors, which are suitable for zinc hydride arresters of 220kV and below in 5~10kA system; JSZ-8 type discharge counters increase photoelectric alarm indication, green indicator light appears in normal operation, when lightning arrester leaks current When the pipe limit value is exceeded, the red indicator light appears, which can be used for online detection of the arrester.

In addition to the function of monitoring the discharge action of the arrester, the arrester monitor can also monitor the leakage current change of the remote arrester, and provide reliable data in time for the operation quality of the arrester to prevent accidents and improve the reliability of the operation of the power system.

JCQ-C series monitor adopts ZnO electric pick-up piece, which is suitable for zinc oxide arrester of 330kV and below in 5~10KA system. JCQ-C5 type monitor is a new type of monitor developed and produced by our company. It has a fault alarm flashing device. The JCQ-C6 monitor has a built-in dual ammeter. In addition to monitoring the leakage current flowing through the aerator, it can also monitor The leakage current flowing through the appearance of the arrester is referenced for operation.

1. Adopting novel and unique overall structural design, compact structure, superior sealing performance, stable and reliable work;

2. Aluminum-magnesium alloy die-casting, bright magnetic shielding effect, beautiful and sturdy, corrosion-resistant shock absorption, easy to transport and install, long service life;

3. Using three-position electromagnetic counter, can record nearly a thousand discharges, automatically return to zero after full scale, cycle count work, no need to clear;

4. The current measurement adopts a special non-linear scale milliampere meter, which has the advantages of clear reading, high current discrimination and high vibration resistance;

5. The special safety meter uses the color scale to mark the leakage current running area of the arrester, which is convenient for judging the running state of the arrester (see performance parameter table);

6. With fault alarm, after the leakage current of the arrester exceeds the set value, the alarm signal can be automatically issued. The signal mode is red and green alternately flashing, which meets the human visual and physiological characteristics and improves the early warning capability.
