Abstract
The present invention provides a kind of high-voltage charge display devices, including several sensors being connect with high voltage alive equipment and with the one-to-one display of sensor, blocking device is provided in each sensor, blocking device passes through the signal transmssion line display corresponding with feedback line is latched respectively and connects, display obtains whether equipment is charged by signal transmssion line, is latched by being latched feedback line to equipment.The present invention is monitored equipment live information by two-way contact route, it is more safe and reliable, wherein when a line fault, another can temporarily play complete signal transmission and blocking function, do not influence equipment and use and investigation failure is facilitated to repair.
Description
Technical field
The present invention relates to electric apparatus control apparatus field, specifically a kind of high-voltage charge display device.
Background technique
High-voltage charge display device is that one kind is directly installed on indoor electric equipment, intuitively show electrical equipment whether band
There is the indicative safety device of working voltage.When equipment has working voltage, which flashes, and warns people
High-tension apparatus electrification, then without instruction when no electricity.
Existing high-voltage charge display device is the field coupling principle using between high voltage electric field and sensor, safety away from
Measurement (contactless) from outer progress induction type, high-voltage electriferous display locking device are made of sensor, two part of display, are passed
Sensor is directed at three-phase electrical body and ground connection, with high-voltage charged body without directly contacting, and keeps certain safe distance, it receives height
Pressure zone electricity bulk electric field signal, and send display to and be compared judgement；When equipment under test or network charge, three-phase indicator light
Bright, " operation " indicator light extinguishes, and exports forced blocking signal.When equipment under test or not charged network, three-phase indicator light is all
Extinguish, " operation " indicator light is bright, while removing locked signal, can carry out equipment operation.Device uses individual-phase control, Ren Heyi
When mutually charging, that is, flashing light alarm, and export forced blocking signal.Detection device is usually additionally provided in display, once discovery failure
The equipment of the signal whole of forced blocking immediately.
Manifold type high-voltage charge display device is easy the interference by external signal, and sensor is once disturbed, for safety
For the sake of equipment will be forced to be latched, influence normal use.
Summary of the invention
The present invention in order to solve problems in the prior art, provides a kind of high-voltage charge display device, passes through two-way contact
Route is monitored equipment live information, more securely and reliably, wherein another can temporarily play when a line fault
Complete signal transmission and blocking function do not influence equipment and use and investigation failure is facilitated to repair.
The present invention include several sensors being connect with high voltage alive equipment and with the one-to-one display of sensor,
It is provided with blocking device in each sensor, blocking device passes through signal transmssion line respectively and is latched corresponding aobvious of feedback line
Show that device connects, display obtains whether equipment is charged by signal transmssion line, is latched by being latched feedback line to equipment.
It is further improved, the display interior is provided with fault detection means, to not having an equipment individually to be examined
It surveys, when detecting its signal transmission fault, forced blocking is carried out to equipment by locking feedback line, and anti-by locking simultaneously
Feeder line persistently receives the band power information of sensor.
The beneficial effects of the invention are that:
1, equipment live information is monitored by two-way contact route, more securely and reliably.
2, wherein a line fault when, another can temporarily play the transmission of complete signal and blocking function, not shadow
Equipment is rung to use and investigation failure is facilitated to repair.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Structure of the invention as shown in Figure 1, include several sensors being connect with high voltage alive equipment and with sensor one
One corresponding display is provided with blocking device in each sensor, and blocking device passes through signal transmssion line respectively and locking is anti-
The corresponding display connection of feeder line, display obtains whether equipment is charged by signal transmssion line, by being latched feedback line
Equipment is latched.
It is further improved, the display interior is provided with fault detection means, to not having an equipment individually to be examined
It surveys, when detecting its signal transmission fault, forced blocking is carried out to equipment by locking feedback line, and anti-by locking simultaneously
Feeder line persistently receives the band power information of sensor.
There are many concrete application approach of the present invention, the above is only a preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, it can also make several improvements, this
A little improve also should be regarded as protection scope of the present invention.
