Description
Technical field
High voltage electrical apparatus technical field is the utility model is related to, is a kind of high voltage display device, more particularly to it is indoor non-
Contact high voltage display device.
Background technology
It is easy to change energy form because electric power has, high concentration and can infinitely divides, can be mass-produced and long distance
From characteristics such as conveyings, make electric power development and level of application into one of important symbol for weighing its social modernization's level height.
With extensive use of the electric power in production and living, electric load is also increasing, the voltage class of power transmission and distribution also more and more higher,
And electricity it is invisible and audible does not cause people can not intuitively identify whether all kinds of power equipments powered, that thus brings is various
Electric power safety accident emerges in an endless stream.
High voltage display device suitable for indoor rated voltage is 3,6,10,27.5,35kV, frequency is that 50Hz is opened
Close in equipment, the whether powered signal of electrical body can be delivered on light-emitting component or audio element, to reflect display dress
Install place's high tension loop charged state, or locking high-tension switch gear simultaneously.Its appearance solves the sightless problem of electricity,
Can effectively prevent due to people can not grasp to equipment live situation and caused by high pressure electric shock accidents and equipment Damage by Short Circuit
Accident, particularly to preventing line side live ground wiring, powered splice grafting banister and prevent that personnel's false touch charging equipment can
Play obvious warning function.According to the difference of design principle, it is powered that high voltage display device can be divided into induction-type high-voltage
Display device and capacitive high voltage charged display device.
In the prior art, sensor and display unit are by cable connection, utilize sensor and high-voltage alternating electric field
Between field coupling principle, outside safe distance carry out induction type, non-contact measurement, work of the sensor in alternating electric field
With lower generation charge inducing, input signal of the induced-current as device is formed, after amplifying by inside, this is felt by cable
Induced current signal is sent to display unit.Its security is poor, difficulty of construction is high, maintenance cost is larger.
Utility model content
The purpose of this utility model is the shortcomings that overcoming above-mentioned prior art, there is provided a kind of indoor non-contact type high voltage is powered
Display device, the potential safety hazard that hot line job can be avoided to bring.
To achieve these goals, technical scheme provided by the utility model is：
Indoor non-contact type high voltage charged display device, including sensing unit, display unit, the interlocking letter sequentially electrically connected
Number output unit and the power supply for each unit power supply；Wherein,
The sensing unit is provided with wireless radio transmission module, for the electriferous state for sensing electric major loop to be led to
The form for crossing wireless signal is sent to display unit；
The display unit is provided with less radio-frequency receiving module, for showing " the having electricity " or " no electricity " of electric major loop
Signal.
Preferably, the wireless radio transmission module is RFID reader.
It is highly preferred that the less radio-frequency receiving module is RF tag, the less radio-frequency of RFID reader transmitting is received
Signal.
Preferably, the interlocking signal output unit, according to " the having electricity " of electric major loop or " no electricity " signal, to electric
The interlock of equipment sends " locking " or " unblock " instruction.
Preferably, the interlocking signal output unit is made up of reset chip, on-off circuit and magnetic latching relay, institute
One group of normally opened node for stating magnetic latching relay is output control terminal, the output control terminal of the signal transacting and control unit with
The input of on-off circuit is connected.
Indoor non-contact type high voltage charged display device provided by the utility model, by sensing unit and display unit
In built-in wireless radio frequency modules, the transmission of " having electricity " or " no electricity " signal is carried out by radio frequency signal, has abandoned wired company
Connect pattern, cable need not be arranged during construction, its security is higher, and difficulty of construction is low, and maintenance cost is smaller.
Brief description of the drawings
Fig. 1 is indoor contactless scheme of installation provided by the utility model.
Embodiment
In order to more clearly describe technology contents of the present utility model, enter traveling one with reference to specific embodiment
The description of step.
As shown in figure 1, be indoor contactless scheme of installation provided by the utility model, the indoor contactless height
Charged display device is pressed to include the sensing unit 2 for the electriferous state of induction electric major loop 1, for showing electric major loop 1
The display unit 3 of " having electricity " or " no electricity " signal, interlocking signal output unit 4 and the power supply for each unit power supply；Wherein, institute
State sensing unit 2 and wireless radio transmission module is installed, for the electriferous state for sensing electric major loop 1 to be passed through into wireless communication
Number a is sent to display unit 3；The display unit 3 is provided with less radio-frequency receiving module, for showing electric major loop 1
" having electricity " or " no electricity " signal；The interlocking signal output unit 4, according to " the having electricity " of electric major loop 1 or " no electricity " signal,
" locking " or " unblock " instruction is sent to the interlock c of electrical equipment.
As a kind of preferred scheme, the wireless radio transmission module is RFID reader；The less radio-frequency receives mould
Block is RF tag, receives the radio frequency signal of RFID reader transmitting.
As a kind of preferred scheme, the interlocking signal output unit 4 be by reset chip, on-off circuit and magnetic keep after
