Description
Technical field
The present invention relates to a kind of test support equipment of technical field of power systems, particularly relate 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 one of Key experiments project ensureing that power system security effectively runs.High-potting district, zone of alarm and place of safety is contained in the region of carrying out high-potting, as shown in Figure 1, wherein high-potting district is high-tension testing apparatus and the region that must meet the requirement of high-potting safe distance, refer generally to the region of distance high-voltage testing equipment about 5m, when high-potting is carried out, because the trial voltage of testing equipment is higher, this region does not allow anyone close.Zone of alarm is the region comparatively dangerous relative to place of safety near high-potting district, it is generally the region around 2m distance around high-potting district, when high-potting is carried out, this region does not allow anyone close in principle yet, if any personnel near can being reminded by the form of reporting to the police.Namely place of safety is the region beyond zone of alarm, the region that people can be freely movable.
For avoiding unrelated person to be strayed into high-potting district, traditional method arranges fence in the periphery of zone of alarm and hangs alarming sign, and the personnel that arrange work in addition make an inspection tour zone of alarm, enters high-potting district to prevent unrelated person.But because staff's carelessness is easy to generation personnel Wu Chuan high-potting district, cause personnel to injure the generation with the security incident such as device damage.
For avoiding above-mentioned accident to occur, occurred audible and visible alarm fence one class alarming product, this series products is also the outer peripheral areas being arranged on zone of alarm, mainly comprises fence and alarm.Carrying out in high-potting process, enter into when reporting to the police trivial when there being personnel, alarm sends sound and light alarm signal, and warning personnel leave hazardous location, thus avoids the security incident such as casualties and device damage occurs.But this series products only just sends alerting signal when personnel enter into zone of alarm, likely there is personal electric shock event because personnel have little time to withdraw.And this series products in use, 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, and personnel still likely can occur and to get an electric shock the security incident such as injures and deaths and device damage.In addition, when alarm breaks down or be destroyed, this series products can not play warning function, adds the possibility that the security incident such as casualties and device damage occurs.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of high-potting area alarm unit can effectively avoiding 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:
High-potting area alarm unit, comprise main frame with some first infrared eyes being arranged on zone of alarm and place of safety intersection be connected with main frame respectively and some second infrared eyes being arranged on high-potting district and zone of alarm intersection, described main frame inside is provided with power module, alarm module and the control module for controlling high-voltage test electric power output; The input end of power module connects AC power by air switch, and the output terminal of power module is connected with alarm module and control module respectively.
Be provided with rectification unit in 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 alarm module and control module respectively.
Alarm module comprises the alarm for sending alerting signal and the alarm control circuit for controlling alarm equipment alarm, alarm control circuit, alarm and power module are connected in series formation alarm circuit, described alarm control circuit comprises the some normally opened contacts triggered by the first infrared eye be arranged in parallel, and described normally opened contact and the first infrared eye one_to_one corresponding are arranged.
Control module comprises output terminal and connects the power output terminal of high-tension testing apparatus and the output control circuit for controlling power output terminal output voltage, described output control circuit comprise be connected in series between power module outlet some by second infrared eye trigger normally closed contact and auxiliary reclay, described normally closed contact and the second infrared eye one_to_one corresponding are arranged; The normally opened contact of auxiliary reclay is connected in series with between the input end of described power output terminal and AC power.
Improvement of the present invention is: described alarm is audible-visual annunciator.
Owing to have employed technique scheme, the technical progress that the present invention obtains is:
Sound and light alarm and automatic experiment power supply two kinds of protected modes of cutting off are incorporated in high-potting warning by the present invention, improve the security of high-potting.When there being personnel near zone of alarm, the present invention sounds and light two kinds of alarm signals, reminds and leaves high-potting region, because now personnel are positioned at the zone of alarm of high-potting, the security incident such as casualties and device damage can not occur.When there being personnel to enter into high-potting region, automatically cutting off testing equipment power supply by the present invention, stopping high-potting, thus can effectively avoid high-potting region that the security incident such as casualties and device damage occurs.
