Due to poor sealing, lightning arrester action counter may enter the moisture and water in the process of operation, the internal components lead to corrosion, can not operate normally, counter action is very important for the reliability of power system, it is the record of arrester in normal operation by an important parameter of lightning frequency statistics. It can provide an important basis for the power system staff to check the lightning arrester. Therefore, "Regulations", should check at least once a year.
The Zinc oxide arrester discharge Counter Tester is used to check the reliability of all kinds of arrester counter actions. It is suitable for checking and verifying discharge action of valve type surge arrester (including carbonized silicon common valve type (FZ and FCD) and carbonized silicon magnetic blow valve type (FCZ and FCD) and discharge recorder in Zinc Oxide arrester). The instrument conforms to the electric power industry standard DL474.5-92 "Field Guide for insulation test - arrester test standards, test application in power plant, substation and repair workshop, test room under various conditions, the instrument adopts the hand-held design, beautiful appearance, easy to carry, it replaces the traditional test instruments and heavy test method for testing arrester action counter, the majority of professional staff welcome.
1. Test principle uses capacitance charging and discharging method: charging time is short, discharge speed is fast;
2. Easy to operate: one button can complete the automatic charge and discharge process, the time interval of 1~2 seconds / time;
3.Wide range of application: high voltage output adjustable 0 ~ 1300V, can meet all kinds of counter action voltage;
4. Safe and reliable: the instrument shell uses ABS plastic material, high voltage output without metal exposure, operator safety is guaranteed, will not be electric shock;
5. Test times: one charge can be operated more than 2000 times;
6. Easy to test: this instrument is equipped with a set of test lines, but also a rod line, the test can meet the needs of different test methods.
1、Output voltage：0～1300V adjustable；
3、Power supply：charging battery；
