Description
Technical field
The utility model includes voltage adjustment of on-load relay technical field, is specifically related to a kind of on-load voltage regulation Buchholz relay automatic exhaust device.
Background technology
When transformer carries out normal on-load voltage regulation, the gases such as the gas of trace will be produced during on-load voltage regulation work, when these methane gas are accumulated to a certain amount of, just light gas alarming signal can be produced, as being exhausted operation not in time, will cause transformer can not normally pressure regulation, power supply quality be bad and will cause serious adverse consequences to the equipment of user.The maintenance of annual transformer will carry out a large amount of bleedings, and simple bleeding needs department's cooperatings such as power transformation, O&M, scheduling, and company will drop into a large amount of work every year for this reason.Maintenance teams and groups guardian and operator is needed to show up in each bleeding process, and be equipped with vehicle, and the staff of O&M also needs to show up and changes throwing trip signal, calculate thus, minimum needs 6 staff's two vehicles complete this work, about 500 man-hours of annual Cummulative, and vehicle is accumulative travels kilometer about up to ten thousand, this not only consumes a large amount of human and material resources and exists certain dangerous in the process of exhaust, constitutes a threat to the personal safety of staff.
Therefore how providing a kind of on-load voltage regulation Buchholz relay automatic exhaust device, can carry out automatic vent, use manpower and material resources sparingly, increase work efficiency on-load voltage regulation Buchholz relay, is the technical problem that those skilled in the art need solution badly.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of on-load voltage regulation Buchholz relay automatic exhaust device.
Technical solution adopted in the utility model is, a kind of on-load voltage regulation Buchholz relay automatic exhaust device, comprise: housing, tracheae is provided with above described housing, below is provided with oil pipe, described tracheae is all connected with relay with oil pipe, is provided with blast pipe above described housing, and described blast pipe is provided with electromagnetic exhaust valve; Described enclosure interior is provided with weight and open cup, and described weight is connected by connecting rod with open cup, and be provided with magnet in described open cup, below is provided with dry-reed contact; Described dry-reed contact is electrically connected with described electromagnetic exhaust valve.
Preferably, vent plug is provided with above described housing.
The beneficial effects of the utility model are:
The on-load voltage regulation Buchholz relay automatic exhaust device that the utility model provides, structure is simple, with low cost, easy to maintenance, can carry out automatic vent, use manpower and material resources sparingly, increase work efficiency on-load voltage regulation Buchholz relay.
Accompanying drawing explanation
The structural representation of the on-load voltage regulation Buchholz relay automatic exhaust device that Fig. 1 provides for the utility model.
In upper figure, the corresponding relation of Reference numeral and component names is:
1 housing; 21 tracheaes; 22 oil pipes; 23 blast pipes; 3 electromagnetic exhaust valves; 4 weights; 5 open cup; 61 magnet; 62 dry-reed contacts; 7 vent plugs.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The on-load voltage regulation Buchholz relay automatic exhaust device that the utility model provides, comprise housing 1, tracheae 21 is provided with above housing 1, below is provided with oil pipe 22, tracheae 21 is all connected with relay with oil pipe 22, be provided with blast pipe 23 above housing 1, blast pipe 23 be provided with electromagnetic exhaust valve 3; Housing 1 inside is provided with weight 4 and open cup 5, and weight 4 is connected by connecting rod with open cup 5, is provided with magnet 61 in open cup 5, and below is provided with dry-reed contact 62; Dry-reed contact 62 is electrically connected with electromagnetic exhaust valve 3.
The installation of the on-load voltage regulation Buchholz relay automatic exhaust device that the utility model provides:
The automatic exhaust device provided by the utility model is arranged on the top of on-load voltage regulation relay, is connected by the tracheae 21 of automatic exhaust device, and fills transformer oil by automatic exhaust device and relay with oil pipe 22 with relay, forms initial condition.
The operation principle of the on-load voltage regulation Buchholz relay automatic exhaust device that the utility model provides:
Due under normal circumstances, automatic exhaust device be full of transformer oil in relay and be connected between the two, therefore the pressure of these two device inside is consistent, and weight 4 and open cup 5 are all in hydraulic oil, and at this moment weight 4 is than open cup 5 weight, weight 4 falls, and by connecting rod, open cup 5 has been pressed, magnet in open cup 5 61 and the dry-reed contact 62 be positioned at below it away from, dry-reed contact 62 disconnects, thus electromagnetic exhaust valve 3 is still closed, blast pipe 23 is not vented.
When transformer carries out on-load voltage regulation, earthenware gas is produced in relay, gas enters above automatic exhaust device from tracheae 21, gas builds up, pasta is forced to decline, when pasta drops to certain position, weight 4 and open cup 5 are all in the middle of gas, now owing to having filled with transformer oil in open cup 5, therefore weight is greater than weight 4, open cup 5 falls, by connecting rod, weight 4 is pressed, magnet 61 in open cup 5 is close with the dry-reed contact 62 be positioned at below it, make dry-reed contact 62 adhesive, connect loop, electromagnetic exhaust valve 3 is opened, gas is slowly discharged along blast pipe 23.Transformer oil is full of automatic exhaust device more gradually, and when oil body is full of, weight 4 declines, and open cup 5 has been pressed, magnet 61 and dry-reed contact 62 away from, dry-reed contact 62 disconnects, and electromagnetic exhaust valve 3 closes, and stops exhaust.Complete automatic vent operation.
The on-load voltage regulation Buchholz relay automatic exhaust device that the utility model provides, structure is simple, with low cost, easy to maintenance, can carry out automatic vent, use manpower and material resources sparingly, increase work efficiency on-load voltage regulation Buchholz relay.
In order to optimize above-mentioned technique effect further, in the utility model, above housing 1, being provided with vent plug 7, being convenient to be vented when mounted, and the extraction failure gas that is in operation.
Apply specific case herein to set forth principle of the present utility model and execution mode, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection range of the utility model claim.
