DXN8D HV Switchgear Voltage Indicator Live Display Device–Holes Size OF 58*31.5MM 

DXN8D HV Switchgear Voltage Indicator Live Display Device–Holes Size OF 58*31.5MM

 

• Specification
• Parameters

• Indoor high-voltage charged display device consists of three sensors and a display connected by wires. It is suitable for indoor high voltage electrical equipment under rated frequency 50Hz and rated voltage 40.5KV. Not only can reflect the circuit charged condition, but also with the electromagnetic lock. To achieve the mandatory locking of switch handles, valves, etc.. The charged display and mandatory 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 circuit is energised, even if the display circuit and the locking circuit fail at the same time, the electromagnetic lock is still in the locking state to prevent misoperation, the purpose of the erroneously energised intervals.

  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 indoor 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.
