Description
Technical field
The utility model belongs to electric power source of early warning technical field, relates in particular to a kind of automatic safe prior-warning device of mistakenly entering charged chamber.
Background technology
Nowadays, " five-defence block " device, in transformer station, has all been installed substantially, indoor equipment can be accomplished " preventing mistakenly entering charged chamber " function substantially.Dan outdoor equipment district, operational outfit does not have fixing fence, a little less than preventing that mistakenly entering charged chamber is with regard to relative thin, generally, just from the operating aspect of equipment, takes measures: install the lockset with " five is anti-" function additional.In fact, can only prevent operations staff's maloperation like this. can not realize and prevent maintainer's mistakenly entering charged chamber, step on charging equipment by mistake.How to strengthen the equipment control in outdoor equipment district, realize maintainer and only enter corresponding maintenance interval, mistakenly entering into charged operation interval does not just seem very important.And the existing document of research is in this respect not a lot, the most representative < < that should be cycle is delivered at first collection of thesis > > of electric power safety forum of < < inquires into and prevents from being strayed into charged interval, outside transformer substation battery limits and maintenance interval management > >, this article has been introduced a kind of fence, utilize infrared signal whether to interrupt having judged whether people or object blocks infrared ray, if, send sound and light alarm, with this, reach the object that is strayed into band point interval.
At equipment during in inspecting state, the electronics stake of laying the Emission and receiving of infrared of a pair of movable type, for completing original path in addition.The personnel of preventing enter adjacent interval, maintenance interval are opened to a passage simultaneously, are convenient to staff's turnover.
The situation that also has possibility person on duty to make an inspection tour, operate and arrange safety practice, operator on duty, when access arrangement district, utilizes a wireless telepilot, the sound of temporarily sounding all clear.Wait making an inspection tour after operation and safety practice arrange and finish, telepilot enable system again.
This system equipment is simple, can prevent from being to a certain extent strayed into the generation of band point interval situation.But also there are following two problems in this system:
1. infrared exoelectron stake alarm range is little, there is no forewarning function.This is the topmost problem of this scheme, and when having people aside through out-of-date, infrared ray cannot detect, and can not carry out pre-alarm, and when people rushes entering into charged intervals, then personal safety also probably occurs in warning.
2. use a teleswitch and may cause having people's access arrangement controls other interval after pressing, can cause casualties equally, to control a plurality of charged intervals be worthless to a telepilot, also can be described as unsafe.
Want in addition grain to be positioned on and in discussion > > mono-literary composition of the < < preventing mistakenly entering charged chamber system of delivering in periodical < < industry practice > >, proposed a kind of method to the management of power equipment naming number, by the encode management unique to equipment, field staff can understand device coding by scanner, know checking apparatus, avoid the mistakenly entering charged chamber maloperation of being correlated with, and propagate into monitor supervision platform by remote information, reach the whether correct order in effective control site operation personnel working position.This method can prevent staff's mistakenly entering charged chamber to a certain extent, but bar code is in outdoor easy damage, and can not fundamentally solve the problem of being strayed into, if still mistakenly entering charged chamber likely while having people hasty.
Summary of the invention
The purpose of this utility model is to propose a kind of little at present up-to-date technical scheme alarm range, there is no the problems such as forewarning function, and this programme has proposed a kind of automatic warning device based on pyroelectric infrared sensor.
To achieve these goals, the technical scheme adopting is: a kind of automatic safe prior-warning device of mistakenly entering charged chamber, be arranged on each porch, electrical equipment interval, by hollow support rails, pyroelectric infrared sensor, analysis system, control circuit, automatic intercepting device, phonetic warning system six parts form, described support bar top is provided with audible-visual annunciator, below is provided with bearing, support bar outside is provided with pyroelectric infrared sensor, voice guard and master switch, described light crossing-signal, voice guard, master switch and pyroelectric sensor are connected by electrical wiring to control module, described analysis system and control circuit are all built in hollow support rails, and control circuit is connected by electric wire with automatic intercepting device, described automatic intercepting device is made as red laser flicker railing, is located at porch, electrical equipment interval.Control circuit is imported in the signal parallel connection of pyroelectric infrared sensor and analysis system into, after control circuit judgement, controls audible-visual annunciator and automatic intercepting device work.
Described voice guard and light crossing-signal are connected on one end of control module, and the other end is connected with master switch, equipment live sensor, pyroelectric sensor, and pyroelectric infrared sensor requires perception argument to be less than or equal to 90 °, to reduce the possibility of false alarm.
Further, described support bar is made as hollow cylindrical, and the left side of support bar is loudspeaker and master switch fixedly, and dead ahead is pyroelectric sensor fixedly.
Principle of work: the signal that described pyroelectric sensor collects pass to control module in conjunction with the whether charged signal of master control room to control audible-visual annunciator duty.By equipment live testing circuit, from master control room, receive this interval equipment ground auxiliary relay signal, whether automatic decision interval is charged, and maintenance and mode of operation are set, and possesses self-checking function.The effect of described pyroelectric infrared sensor is in people enters induction zone time, and signal imports control circuit into.The effect of described analysis system is whether judgment device is charged.Described control circuit is judged and is controlled the duty of audible-visual annunciator by the signal of pyroelectric sensor and analysis system acquisition.
The utility model has the advantages that: equipment is simple, automaticity is high, and detection signal scope is wide, and reliability is strong, and whether energy automatic checkout equipment is charged, can prevent from being strayed into a generation for band point interval situation.
