Application scenarios and advantages
1. Application scenarios
Substations, transmission lines, distribution rooms, etc. are equipped with lightning arresters to record the number of lightning strikes/overvoltage discharges and monitor leakage currents.
Factory power distribution system, large equipment (such as fans and motors) lightning protection, real-time monitoring of the health status of lightning arresters.
The lightning protection grounding system for high-rise buildings and commercial buildings, as well as low-voltage lightning arresters, can ensure electrical safety.
2. Product advantages
The discharge counter clearly records the number of actions, and the JCQ monitor displays the leakage current in real time (such as JCQ-JC1 monitor with an accuracy of mA level).
Wide voltage range (3-220kV), strong impulse withstand (such as JS-8 withstand 4/10 μ s high amplitude impulse 65-100kA), suitable for complex power grid environments.
Ceramic sleeve and modular design, Surge Arrester Disconnector adapts to different lightning arrester structures; The disconnector quickly disengages from the faulty lightning arrester to avoid system risks.
FAQ
How does a discharge counter work?
By recording the current pulses during the operation of the lightning arrester and accumulating the number of discharges, the frequency of lightning strikes/overvoltage can be intuitively reflected.
What is the function of the monitor?
Real time monitoring of lightning arrester leakage current. If the current rises abnormally, it indicates the aging/failure of the lightning arrester and provides early warning for maintenance.
Purchase suggestions
If you need to record the number of discharges: choose JS-8 (medium low voltage) or JCQ (high voltage).
If real-time monitoring of leakage current is required: choose JCQ-JC1 monitor (with digital display, high accuracy).
If low-voltage lightning protection is required: choose YC1.5W series porcelain bushing lightning arrester, suitable for 0.22/0.38kV system.
If customized valve plates are required: Choose D30~D70 series zinc oxide valve plates according to the system voltage and current requirements.
