DXN8D-Q High voltage charged display indicator, connect with transducer, used as switchgear appliance.
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.

Application range and characteristic
The indoor high volt charged display device is composed of three sensors and display(through lead connection) It is applied to certain indoor high volt electric equipment of rated frequency 50HZ and rated volt below 40.5 KV,by this device ,it could indicate charged condition in circuit,besides,it can be coordinate-operated with electromagnetic lock ,which realizes forced lockout of switch handle and controlled by one high volt signal . While , its circuit system is stand-alone and not interfered one another ,just needing the high volt circuit electrified,even if display circuit and latching circuit arise fault simultaneously, the electromagnetic lock still stay in locking state ,which could prevent from mishandle or entering into charged spacing.
