Abstract
The invention discloses a kind of Buchholz relay protective cover, it is not good mainly to solve unshielded its rainproof effect of cover person, using the installation of metal cap is firm, dismounting inconvenience, there are problems that.The protective cover includes the back box of built-in Buchholz relay, and it is fastened on the protective cover in back box, wherein, back box two side edge, which is respectively provided with, is fixed on the end hoop that Buchholz relay enters outlet line, end hoop includes the lower end hoop being connected with back box, and the end being connected by hinge and lower end hoop is bound round and covered, and the observation panel of U-shaped is respectively provided with before and after protective cover and back box.By such scheme, the present invention has the advantages that simple in construction, easy for installation, connection is reliable, rainproof effect is good, in oil-filled transformer using having very high practical value and promotional value.
Description
Technical field
The present invention relates to a kind of Buchholz relay protective cover.
Background technology
Buchholz relay (i.e. gas relay), is a kind of protection device of oil-filled transformer, installed in transformer
Between conservator and fuel tank, required according to mounting process, the transformer for installing Buchholz relay has 1%-1.5%'s when mounted
The gradient, in power transformer interior fault, oil decomposition produces gas or causes oil flow surge, acts the contact of gas relay, connects
The logical control loop specified, and signal alarm (light gas) is sent in time or starting protection element cuts off transformer (weight watt automatically
This).
Most of oil-filled transformers are installed out of doors, and its Buchholz relay needs to take rain-proof measure, at present, gas after
Using sealing ring is added between electrical equipment body and rain-proof shell, using bolt connection, sealing ring easily splits through wind and weather
Line, its rainproof effect is not good, it is necessary to regularly replace.Buchholz relay internal water accumulation is caused after sealing ring failure, Buchholz relay is touched
Point misoperation, sends alarm signal, when serious, grave gas action, causes excision transformer station high-voltage side bus, influences power supply reliability.
In order to solve the unshielded cover of Buchholz relay, some transformers are bundled on pipeline using U-shaped metal cap, strong wind day
Gas, which there may be, to be stirred, and is discharged between charging equipment, and its colligation is insecure, dismounting is inconvenient, there is potential safety hazard.
The content of the invention
It is an object of the invention to provide a kind of Buchholz relay protective cover, mainly solve present in prior art without anti-
Shield person's rainproof effect is not good, using the installation of metal cap is not firm, dismounting is inconvenient, there are problems that.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of Buchholz relay protective cover, includes the back box of built-in Buchholz relay, and the protection being fastened in back box
Lid, wherein, back box two side edge, which is respectively provided with, is fixed on the end hoop that Buchholz relay enters outlet line, and end hoop includes and back box
The lower end hoop of connection, and the end being connected by hinge and lower end hoop are bound round and covered, and the observation of U-shaped is respectively provided with before and after protective cover and back box
Mouthful.
Further, protective cover both sides lower edge and back box both sides top edge are respectively provided with for running through Buchholz relay oil pipe
The semicircle orifice on road.
Compared with prior art, the invention has the advantages that：
Buchholz relay is placed in protective cover back box by the present invention, and oil pipe is fixed on by the end hoop for being distributed in back box both sides
Lu Shang, protective cover is fastened in back box, is fixed using bolt, in repair and maintenance, only need to remove bolt, and this is prevented
The back box and protective cover of shield are respectively provided with Buchholz relay viewing glass mouthful, facilitate gas feelings in walkaround inspection Buchholz relay
Condition.The invention has the advantages that simple in construction, easy for installation, connection is reliable, rainproof effect is good, is utilized in oil-filled transformer
With very high practical value and promotional value.
Brief description of the drawings
Fig. 1 is protective cover top view.
Fig. 2 is the structural representation of back box.
Fig. 3 is the structural representation of protective cover.
In above-mentioned accompanying drawing, the corresponding component names of reference are as follows：
1- back box, 2- protective covers, 3- ends hoop, 4- lower ends hoop, 5- ends hoop lid, 6- observation panels, 7- semicircle orifices.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
Embodiment
As shown in Figure 1 to Figure 3, a kind of Buchholz relay protective cover includes the back box 1 of built-in Buchholz relay, and fastens
Protective cover 2 in back box 1, the two side edge of back box 1, which is respectively provided with, is fixed on the end hoop 3 that Buchholz relay enters outlet line,
Wherein, end hoop 3 includes the lower end hoop 4 being connected with back box 1, and lid 5 is bound round at the ends being connected by hinge and lower end hoop 4, in order to protect
The weather seal of end hoop 3 is demonstrate,proved, sealing ring is equipped with the semicircle of lower end hoop 4 and end hoop lid 5, may also function as protective cover damping.
Walkaround inspection, is respectively provided with the observation panel 6 of U-shaped before and after protective cover 2 and back box 1 for convenience.
The both sides lower edge of protective cover 2 and the both sides top edge of back box 1 of the protective cover are respectively provided with for running through Buchholz relay
The semicircle orifice 7 of oil pipe line.
Above-described embodiment is only the preferred embodiments of the present invention, not limiting the scope of the invention, as long as using
The design principle of the present invention, and the change for carrying out non-creativeness work on this basis and making, all should belong to the present invention's
Within protection domain.
