• DXN-Q Inductive 7.2kV High Voltage Live Display Device Sensor Arrester Temperature And Humidity Controller

  The indoor high-voltage live display device consists of three sensors and a display connected by wires. Applicable to rated frequency 50Hz. On indoor high-voltage electrical equipment with a rated voltage of 40.5kV. It can not only reflect the charging status of the circuit, but also cooperate with the electromagnetic lock. Realize forced locking of switch handles, valves, etc. Both the live display and forced locking are controlled by the same high-voltage signal, but the circuit systems are independent of each other and do not interfere with each other. As long as the high-voltage circuit is charged, even if the display circuit and the locking circuit fail at the same time, the electromagnetic lock will still be in a locked state to prevent misoperation. , misleading the purpose of electrified separation.

• DXN-Q 10kv Indoor Live Display High Voltage Charged Display Device

  The DXN series indoor high voltage 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 40.5KV, 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.

  Implement the standard DL/T538 “High-voltage live display device”; DL/T593 “Common technical requirements for high-voltage switchgear and control equipment standards”; JB/T10305 “3.6kV~40.5kV high-voltage equipment users Internal organic material pillar insulator technical conditions”; GB/T7354 “Partial discharge measurement”

  Working Principle

  The device uses the electric field coupling principle between the high-voltage electric field and the sensor to make inductive (non-contact) measurements at a safe distance. The high-voltage charged display blocking device consists of two parts: the sensor and the display. The sensor has three branches, which are aligned with the “A, B, C” three-phase charged body, without direct contact with the high-voltage charged body, and maintain a certain safety distance;
  When the equipment or network under test is charged, the “A, B, C” three-phase indicator lights up, the “operation” indicator goes out, and a forced blocking signal is output.
  When the equipment or network under test is not energised, the “A, B, C” indicators go out and the “operation” indicator lights up, while the blocking signal is released and the equipment can be operated. The device is controlled by phase separation, and when any phase is energised, the alarm flashes and a forced blocking signal is output.
  When the display loses control power, the display outputs a forced blocking signal to maintain the blocking state. The display is equipped with a “self-test” function, which automatically detects the various functional modules of the sensor and the display, and in the event of any malfunction of the device, the “power” indicator lights up, the “operation” indicator does not light up, and the forced latching signal is always output to maintain the latching state. In the event of any malfunction of the unit, the ‘power’ indicator remains on and the ‘operate’ indicator does not illuminate.
