DXN-Q Indoor 7.2-40.5kV HV Live Display Device Voltage Indicator—Holes Sizes OF 92*44MM
Indoor high-voltage charged display device consists of three sensors and a display connected by a number line. Apply to the rated frequency 50Hz, rated voltage 40.5kV below the indoor high-voltage electrical equipment, both to reflect the circuit charged condition, but also with the electromagnetic lock with the realisation of mandatory locking switch handle, valves and so on. Powered display and forced locking are controlled by the same high-voltage signal, but the circuit system is independent of each other, do not interfere with each other, as long as the high-voltage circuits are powered, even if the display circuit and locking circuit failure at the same time, the electromagnetic lock is still in the locking state to prevent misoperation, accidentally enter the powered interval.
This product is used to provide a switchgear equipment circuit voltage information at the installation status to the operator. As a result of its internal circuitry of low-power light-emitting element, which makes low power consumption, more stable performance and higher reliability. For the user test double-loop phase conveniently, indicator(recommend type) panel setting the end of the test phase, meanwhile the frame of indicator (recommend type) shell adopts front end removable. And the user can change the indicator without opening the indicator shell.
Widely used for indooe 7.2, 12, 24, 40.5kV, frequency of 50Hz high voltage electrical equipment, and supporting the use of the voltage sensor, it can reflect the high voltage live situation, and voltage sensor support, but also to improve the anti-error performance ancillary products.
