Description
Technical field
This utility model is related to electric relay protection circuit, and especially a kind of Transformer Heavy Gas protect electric loop.
Background technology
Transformator transmits the visual plant of electric energy as power industry, and the normal operation of transformator concerns electric energy transmission effect
Rate, affects economic index, therefore the relay protection of transformator is quite important.Protect for grave gas, some needs input protections have
Need not put into protection, grave gas protection is thrown in part, operationally produces misoperation because signal is disturbed, stop jumping transformation
Device.Have plenty of special ruuning situation to require grave gas trip, be changed to signalling form.Therefore design a kind of transformation to think highly of watt
This protection electric loop becomes technical problem urgently to be resolved hurrily at present.
Utility model content
The purpose of this utility model is to provide a kind of Transformer Heavy Gas protection electric loop, and the device further improves electricity
Gas relay protection function, it is ensured that the more secure economic even running of industrial enterprise, is carried out in Transformer Heavy Gas protective loop
Innovative design, it is achieved that transformator tripping transformator normal power supply, shadow because of error reporting grave gas when special circumstances are run
Acoustic system runs.
The purpose of this utility model is realized by following technical proposals.
A kind of Transformer Heavy Gas protect electric loop, including being located on transformer coil primary return and secondary loop
Circuit breaker Q F2, QF1, circuit breaker Q F1, QF2 are respectively connecting to auxiliary reclay KOM, and auxiliary reclay KOM is by connection
Piece XE or permutator are connected to signal relay KS, and signal relay KS is connected to Buchholz relay KG；Signal relay KS
Controller is respectively connecting to Buchholz relay KG.
Preferably, circuit breaker Q F2 is the vacuum circuit breaker on transformer coil primary return, circuit breaker Q F1
For the chopper on secondary loop；The vacuum circuit breaker QF2 and circuit breaker Q F1 are provided with breaking coil YT.
Preferably, connection sheet XE is connected with a resistance R.
Preferably, the auxiliary reclay KOM sets two pairs of contacts.
Relative to prior art, the beneficial effects of the utility model are：
The loop can effectively ensure that industrial enterprise's electric circuit even running, using in Transformer Heavy Gas protective loop
One resistance of middle interpolation, and conversion connection sheet (or permutator), solve transformator when special circumstances are run because of error reporting
Grave gas tripping and affect transformator normal power supply, cause the abnormal phenomenon of system operation.
Description of the drawings
Fig. 1 is this utility model electric loop schematic diagram.
Equipment list
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to this utility model.
As shown in figure 1, the Transformer Heavy Gas protection electric loop, true on transformer coil primary return including being located at
Circuit breaker Q F2 in empty circuit breaker Q F1 and secondary loop, circuit breaker Q F1, QF2 are respectively connecting to auxiliary reclay KOM,
Auxiliary reclay KOM is connected to signal relay KS by connection sheet XE (or permutator), and auxiliary reclay KOM sets two pairs and touches
Point.Connection sheet XE (or permutator) is grounded after connecting a resistance R.Signal relay KS is connected to Buchholz relay KG, is becoming
In depressor grave gas protection electric loop, conversion XE (or permutator) and resistance R in flakes is installed, reaches grave gas
Convenient operation between tripping operation and signalling during action.
In this loop, the upper contact of Buchholz relay KG connects controller signals, is light gas protecting；Lower contact is grave gas
Protection, through signal relay KS, starts outlet auxiliary reclay KOM, after two pairs of closings of contact of KOM, makes vacuum circuit breaker respectively
Device QF1, circuit breaker Q F2, breaking coil YT excitations.Tripping transformator both sides chopper, i.e. the circuit course of work is as follows：
Signal is negative to direct-flow positive pole+→ Buchholz relay KG → signal relay KS → auxiliary reclay KOM → direct current
Pole-, start KOM.
Signal to direct-flow positive pole+→ auxiliary reclay KOM → vacuum circuit breaker QF1 → breaking coil YT → direct current negative pole-,
Tripping vacuum circuit breaker QF1.
Signal to direct-flow positive pole+→ auxiliary reclay KOM → circuit breaker Q F2 → breaking coil YT → direct current negative pole-, tripping
Circuit breaker Q F2.
Connection sheet XE can be connected to resistance R:Signal is to direct-flow positive pole+→ Buchholz relay KG → signal relay KS → resistance
R → direct current negative pole-.Grave gas protection is made not throw tripping operation and only signal.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Assert that specific embodiment of the present utility model is only limitted to this, for this utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all considered as
Belong to the protection domain that this utility model is determined patent by the claims that is submitted to.
