Description
Technical field
The utility model belongs to Buchholz relay field, particularly relates to a kind of new type of relay.
Background technology
Buchholz relay is the transformer main protective device of one used; be contained in the pipeline between the oil conservator of transformer and fuel tank; when oil decomposition generation gas in transformer or when causing oil flow surge; make the contact action of Buchholz relay; connect the control loop of specifying, and generation signal alarm (light gas) or pneumatic protection component excise transformer (grave gas) automatically in time.
Transformer causes the reason of the light gas action of Buchholz relay: 1 is because oil strain, oiling or cooling system imprecision are so that air enters transformer, 2 is because temperature declines or leakage of oil causes pasta lower than below the light gas floating drum of Buchholz relay, 3 is that transformer fault can produce the generation gas rate of climb is accelerated, and 4 is Buchholz relay or transformer secondary loop fault.
If the gas produced after the light gas action in transformer does not discharge can produce following harm: do not arrange when methane gas is long, easily cause false oil level, cannot show real oil level.The gas deflation assembly of existing Buchholz relay normally adopts the mode of exhaust thimble, during exhaust, needs people to climb to turn on thimble above transformer to go discharge, and needs when being vented to close transformer, can not hot line job.
Utility model content
The utility model overcomes the deficiency that prior art exists, a kind of structure is simple, esy to use, safe and reliable in order to provide for technical problem to be solved, long service life, can transformer hot line job firedamp drainage gas, reduce a kind of new type of relay affecting production because of firedamp drainage gas.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of new type of relay, comprise relay body, the top of described relay body is provided with gas deflation assembly, described gas deflation assembly comprises the vent plug body be connected with relay chamber body, the side of described vent plug body is provided with blocking cap, be set with blast pipe in described vent plug body and be fixedly connected with blast pipe by nut, described blast pipe entirety is in bending and the outlet of described blast pipe is downward, and the exit of blast pipe is connected with safety-valve.
Preferably, the outlet of described blast pipe is arranged on the middle and lower part of described relay body.
Preferably, its components is provided with in described relay chamber body, described its components comprises upper shed cup and the under shed cup of band dry-reed contact, support and oil-feed baffle plate, the rear end of upper shed cup and under shed cup is provided with counterweight, the side of the dry-reed contact of upper shed cup and under shed cup is provided with permanent magnet, identical with the height of dry-reed contact on the sidewall that described permanent magnet is fixedly installed on relay chamber body, described support is fixedly installed in relay chamber body, and support is provided with baffle plate.
Preferably, the material of described blast pipe is copper pipe.
The utility model compared with prior art has following beneficial effect: the utility model utilizes blast pipe and safety-valve to replace original exhaust thimble used, after light gas action produces gas, methane gas just can be discharged by the door that only needs to open the safety-valve, safety-valve is arranged on operating personnel can maneuverable place, operating personnel are not needed to operate thimble exhaust aloft, security incident can not be produced, use safety valve in addition, operating personnel not be used in contact transformer, so can operate when transformer is charged, production can not be affected because of firedamp drainage gas.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the structural representation of a kind of new type of relay of the utility model.
Fig. 2 is the internal structure schematic diagram of new type of relay.
In figure: 1 is relay body, 2 is gas deflation assembly, and 21 is vent plug body, 22 is blocking cap, and 23 is blast pipe, and 24 is safety-valve, 3 is its components, and 31 is upper shed cup, and 32 is under shed cup, 33 is dry-reed contact, 34 is counterweight, and 35 is support, and 36 is permanent magnet, 37 is oil-feed baffle plate, and 38 is baffle plate.
Embodiment
As shown in Figure 1, a kind of new type of relay, comprise relay body 1, the top of described relay body 1 is provided with gas deflation assembly 2, described gas deflation assembly 2 comprises the vent plug body 21 with relay body 1 intracavity inter-connection, the side of described vent plug body 21 is provided with blocking cap 22, be set with blast pipe 23 in described vent plug body 21 and be fixedly connected with blast pipe 23 by nut, described blast pipe 23 entirety is in bending and the outlet of described blast pipe 23 is downward, and the exit of blast pipe 23 is connected with safety-valve 24.
Further, the outlet of described blast pipe 23 is arranged on the middle and lower part of described relay body 1.The outlet of blast pipe 23 being arranged on herein can a handled easily workman switch safety valve 24, firedamp drainage gas easily.
As shown in Figure 2, its components 3 is provided with in described relay body 1 inner chamber, described its components 3 comprises upper shed cup 31 and the under shed cup 32 of band dry-reed contact 33, support 35 and oil-feed baffle plate 37, upper shed cup 31 is provided with counterweight 34 with the rear end of under shed cup 32, upper shed cup 31 is provided with permanent magnet 36 with the side of the dry-reed contact 33 of under shed cup 32, identical with the height of dry-reed contact 33 on the sidewall that described permanent magnet 36 is fixedly installed on relay body 1 inner chamber, described support 35 is fixedly installed in relay body 1 inner chamber, support 35 is provided with baffle plate 38.
The course of work of its components 3 is: upper shed cup 31 and under shed cup 32 are all be immersed in oil, the moment that the torque ratio counterweight 34 produced due to upper shed cup 31 or under shed cup 32 and the annex gravity in oil produces is little, so upper shed cup 31 and under shed cup 32 are all in lifting position, dry-reed contact 33 disconnects, when the air accumulation produced in oil is on the top of relay, pasta is forced to decline, upper shed cup 31 exposes pasta, , heavy the produced moment of oil that upper shed cup 31 and the aerial gravity of annex add in cup is greater than the moment that counterweight 34 produces, therefore upper shed cup 31 rotates along clockwise direction, and drive permanent magnet 36 near dry-reed contact 33, dry-reed contact 33 relies on magneticaction and closes, send the anticipating signal of light gas.
Above-described embodiment is the Buchholz relay that the utility model applies to baffle-type, and the utility model also can apply on the Buchholz relay of cartridge type in addition.
The scheme that the utility model adopts in addition can realize by carrying out transformation on original relay, first first exhaust thimble is removed from original relay, then the blast pipe 23 made is inserted in vent plug body 21, cushion cover is increased between blast pipe 23 and vent plug body 21, ensure the sealing property of blast pipe 23, with nut, blast pipe 23 and vent plug body 21 are fixed, finally increase safety-valve 24 at the end of blast pipe 23.Whole transformation process is simple, improvement cost is low, need not change old relay, has greatly saved production cost.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
