Description
Technical field
The present invention relates to electrical safety field, the induction type electric of specifically a kind of belt discharge protection of pipe shows device.
Background technology
The induction type electric of high-voltage board shows that the sensor of device is poured with epoxy resin post insulator style product at present, leads to
Pumping voltage capacitance plug is crossed, power supply of certain voltage as display and blocking device is extracted from electrification in high voltage circuit.It can be used as
Disconnecting switch, earthing switch and other support insulators use.With high intensity, resistance to electric arc ability is strong, and partial discharge quantity is small etc.
Feature.By showing that device is understood in depth to induction type electric, discovery has these following situations to be still not perfect, and can improve, more
Good solution, influence of the high voltage to electrification display and personnel.
1, by taking out voltage capacitance plug, certain voltage is extracted from electrification in high voltage circuit as display and blocking device
Power supply, it can be seen that this display is series in electrification in high voltage circuit, and a current source is equivalent to, and open lines will go out
Existing high voltage.
2, in conventional high-pressure system, when being examined into horizontal high voltage pressure resistance to high-voltage board, need to withdraw from sensor to display
The secondary line of sensor is carried out short circuit grounding, avoids the high voltage occurred when pressure resistance display damage by the circuit of device.It is resistance to
Short circuit line is withdrawn from again after the completion of pressure, restores sensor to the circuit of display, there are many this working quantity, each high pressure
Cabinet has.Withdraw from, be possible to phase sequence mistake occur in recovery process, instruction phase lamp also there is mistake, it is seen that work it is cumbersome.
3, high-pressure system operation in, in fact it could happen that overvoltage electrification display may also be caused to damage.
4, part of the manufacturer is mounted with a button switch on panel, and when operation presses down button, and when pressure test must
Button must be pressed, operation in this way protects the induction type electric to show device.In pressure resistance, if button has been forgotten to press
Get up, there have been display damages.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, provide a kind of induction type band of belt discharge protection of pipe herein

This display can solve induction type electric suitable for the pressure test of high-pressure system and Measuring error technical field
The sensor of display, by the protection of discharge tube, avoids wound of the high voltage to display, personnel in operation or high pressure pressure resistance
Evil, have it is of low cost, securely and reliably, and it is more convenient to use the features such as.
Description of the drawings
Fig. 1 is that the induction type electric of this belt discharge protection of pipe shows the schematic diagram of device.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, a kind of induction type electric of belt discharge protection of pipe shows device, including high-voltage board, insulator 1, electrification
Display 2, connection line 3, connection plug 4, discharge tube 5；Wherein；Insulator 1 is mounted in high-voltage board；Electrification display 2 is pacified
On the panel of high-voltage board；Detectable voltage signals are linked by connection plug 4 in electrification display 2 by connection line 3；It puts
Fulgurite 5 is mounted at the wiring plug in electrification display 2.
The induction type electric of the belt discharge protection of pipe shows that device, discharge tube 5 form a whole with connection plug 4.
This display can solve induction type electric suitable for the pressure test of high-pressure system and Measuring error technical field
The sensor of display, by the protection of discharge tube, avoids wound of the high voltage to display, personnel in operation or high pressure pressure resistance
Evil, have it is of low cost, securely and reliably, and it is more convenient to use the features such as.
