According to the high-voltage test area alarming device, two protection modes, namely, audible and visual alarming and automatic cutoff of a testing power supply are introduced into high-voltage test alarming, so that the safety accidents of loss of life and personal injury, equipment damage and the like of the high-voltage testing area can be effectively prevented, and the safety and the reliability of high-voltage testing are improved.
Description
Technical field
The present invention relates to a kind of test support equipment of technical field of power systems, relate in particular to a kind of warning device.
Background technology
High-potting is the test of test power transformer and other insulation of electrical installation performance quality, is to ensure one of Key experiments project that power system security effectively moves.High-potting district, zone of alarm and place of safety in the zone of carrying out high-potting, have been comprised, as shown in Figure 1, wherein the high-potting district is high-tension testing apparatus and the zone that must satisfy the requirement of high-potting safe distance, refer generally to the zone about distance high-voltage testing equipment 5m, when high-potting is carried out, because the trial voltage of testing equipment is higher, this zone does not allow anyone close.Zone of alarm is near the zone comparatively dangerous with respect to the place of safety, high-potting district, it generally is the zone around 2m distance around the high-potting district, when high-potting was carried out, this zone did not allow anyone close in principle yet, reminded near the form that can pass through to report to the police if any personnel.The place of safety namely is the zone beyond the zone of alarm, and people are the zone of activity freely.
For avoiding unrelated person to be strayed into the high-potting district, traditional method is fence to be set and to hang alarming sign in the periphery of zone of alarm, and the personnel that arrange work in addition make an inspection tour zone of alarm, enters the high-potting district to prevent unrelated person.But rush the high-potting district because staff carelessness is easy to generation personnel mistake, cause personnel to injure generation with the security incident such as device damage.
For avoiding above-mentioned accident to occur, audible and visible alarm fence one class warning product has appearred, and this series products also is arranged on the outer peripheral areas of zone of alarm, mainly comprises fence and alarm.In carrying out the high-potting process, when having personnel to enter into to report to the police when trivial, alarm sends the sound and light alarm signal, and the caution personnel leave the hazardous location, thereby avoid occuring the security incidents such as casualties and device damage.But this series products only just sends alerting signal when personnel enter into zone of alarm, might have little time to withdraw the personal electric shock event that occurs owing to personnel.And this series products in use, and the sound and light alarm signal only plays warning function, and testing equipment is still in running order, and Keep Clear-High Voltage, and property still exists, the security incidents such as injures and deaths and device damage of still might the generation personnel getting an electric shock.In addition, when alarm break down or destroyed situation under, this series products can not be brought into play warning function, has increased the possibility that the security incidents such as casualties and device damage occur.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of high-potting area alarm unit that can effectively avoid security incident to occur when high-potting.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:

Be provided with rectification unit in the power module, the input end of rectification unit is connected to the end opening side of air switch, and the output terminal of rectification unit connects respectively alarm module and control module.
Alarm module comprises be used to the alarm that sends alerting signal with for the alarm control circuit of controlling alarm equipment alarm, alarm control circuit, alarm and power module are connected in series the formation alarm circuit, described alarm control circuit comprises the some normally opened contacts that triggered by the first infrared eye that are arranged in parallel, described normally opened contact and the one by one corresponding setting of the first infrared eye.
Control module comprises the power output terminal of output terminal connection high-tension testing apparatus and is used for the output control circuit of control power output terminal output voltage, described output control circuit comprises some normally closed contact and the auxiliary reclays that triggered by the second infrared eye that are connected in series between the power module outlet, described normally closed contact and the one by one corresponding setting of the second infrared eye; Be connected in series with the normally opened contact of auxiliary reclay between the input end of described power output terminal and the AC power.
Improvement of the present invention is: described alarm is audible-visual annunciator.
Because the technical progress of having adopted technique scheme, the present invention to obtain is:
The present invention is incorporated in the high-potting warning security that has improved high-potting with sound and light alarm and the automatic two kinds of protected modes of experiment power supply of cutting off.When personnel were arranged near zone of alarm, the present invention sounded and two kinds of alarm signals of light, reminded and left the high-potting zone, because personnel's this moment are positioned at the zone of alarm of high-potting, the security incidents such as casualties and device damage can not occur.When having personnel to enter into the high-potting zone, automatically cut off the testing equipment power supply by the present invention, stop high-potting, thereby can effectively avoid the high-potting zone that the security incidents such as casualties and device damage occur.
