1. Overview
Due to poor sealing, moisture and water may enter the arrester action counter during operation, causing the internal components to rust and fail to operate normally. The reliability of the counter action is very important for the power system. It is an important parameter for recording the number of lightning strikes on the arrester during normal operation. It can provide important instruments for power system staff to conduct targeted inspections of the arrester. Therefore, the "Regulations" stipulate that it should be inspected at least once a year.
The lightning strike counter tester is used to verify the reliability of various arrester counter actions. Applicable to the inspection and verification of the discharge action of valve type lightning arresters (including silicon carbide common valve type (FZ and FCD) and silicon carbide magnetic blow valve type (FCZ and FCD) and discharge recorder in zinc oxide lightning arresters.) The instrument complies with the requirements of the power industry standard DL474.5-92 "Guidelines for the Implementation of Field Insulation Tests - Lightning Arrester Tests", and is suitable for tests under various conditions such as power plants, substations, repair workshops, and laboratories. This instrument adopts a handheld design, beautiful appearance, and easy to carry. It replaces the traditional bulky test instruments and test methods for the action test of lightning arrester counters, and is very popular among professionals.
II. Performance characteristics
1. The test principle adopts the capacitor charging and discharging method: short charging time and fast discharge speed;
2. Easy operation: one button can complete the automatic charging and discharging process, and the time interval is 1 to 2 seconds per time;
3. Wide range of applications: high-voltage output 0 to 1300V adjustable, which can meet the action voltage of various counters;
4. Safe and reliable: the instrument shell is made of ABS plastic material, and there is no metal exposure in the high-voltage output, so the operator is safe and will not be shocked;
5. Many tests: more than 2000 times of continuous operation on a single charge;
6. Convenient testing: This instrument is equipped with a set of test wires and a pull rod wire, which can meet the test needs of different methods during the test.
