Description
Technical field
It the utility model is related to a kind of high voltage display device.
Background technology
The high voltage display device device whether powered as line side is judged, it is operation maintenance personnel in transformer station
Grid switching operation provides reliably data supporting.Conventional high-tension electrification display is by capacitive sensing module, from electrification in high voltage loop
Power supply of the certain voltage of middle sensing as display and locking, is influenceed by transformer station's complex electromagnetic environment and switching overvoltage, its
Sensor fault rate is more than 10%, and outlet arrester Leakage Current stability is good, can directly sample, and avoids electromagnetic interference, is
Outdoor charged display device ideal pattern.
The content of the invention
The purpose of this utility model is to provide a kind of powered display of novel high-pressure for lifting charged display device reliability
Device.
Technical solution of the present utility model is:
A kind of New Type High-voltage Presence Indicating Device, it is characterized in that:Voltage sensor including being arranged on high voltage bus nearside
With the Leakage Current sensor for being arranged on arrester Leakage Current outlet;Voltage transformer is by capacitive sensing module, from height
Power supply of certain voltage as display and locking, Leakage Current sensor collection line side arrester are sensed in pressure zone electrical circuit
Leakage Current, voltage transformer are gathered with Leakage Current sensor by OR-gate, and power supply is provided for mainboard;Voltage sensor and
Leakage Current sensor is connected with mainboard, and mainboard is connected to indicator lamp.
Voltage sensor is arranged in the disconnecting switch of line side.
The utility model voltage transformer is gathered with leakage current sensor by OR-gate, when one of signal judges
Circuit charged signal, then mainboard judge that circuit is powered, only two, which write in reply, number judges that circuit is not charged, and mainboard side judges circuit not
It is powered, by such a method, further improve the reliability of charged display device.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is scheme of installation of the present utility model.
Embodiment
A kind of New Type High-voltage Presence Indicating Device, including be arranged on the voltage sensor 9 of the nearside of high voltage bus 10 and set
In the Leakage Current sensor 7 of arrester Leakage Current outlet 6;Voltage transformer is by capacitive sensing module, from high pressure belt
Power supply of certain voltage as display and locking is sensed in electrical circuit, and then judges whether line side is powered;Leakage Current passes
Sensor gathers line side arrester Leakage Current, and voltage transformer is gathered with Leakage Current sensor by OR-gate, is this reality
Power supply is provided with the mainboard 11 of new New Type High-voltage Presence Indicating Device 8;Voltage sensor and Leakage Current sensor and mainboard
Connection, mainboard are connected to indicator lamp 12.
Voltage sensor is arranged in line side disconnecting switch 4.
Leakage Current sensor, by gathering line side arrester Leakage Current, arrester during 110kV circuit normal operations
Leakage Current is about 0.4mA, when the Leakage Current that relay test arrives is more than or equal to 0.4mA, the actuating of relay, is judged as line
Trackside is powered, when Leakage Current is less than 0.4mA, is judged as that line side is not charged.
There are bus bar side disconnecting switch 1, breaker 2, rheology 3, line side disconnecting switch 4, arrester 5 in figure.
