ZL500A switch status indicator is based on the current medium voltage system switch cabinet technology development and the development and design of a novel multi function, intelligent simulation dynamic indicating device. It sets a time loop simulation figure, switch, circuit breaker position, grounding knife switch position, the spring energy storage state, high pressure charged index, high voltage electrified locking and other functions in one, the indicator can be combined, the user can choose according to need, as long as specified in different order types and provide a scheme can, may also be added to a RS485 communication interface, computer monitoring network to provide telemetry, remote data.
