Description
Technical field
It the utility model is related to 110kV-750kV transformer bodies and on-load voltage regulating switch Buchholz relay rain cover.
Background technology
Main transformer body and on-load voltage regulation Buchholz relay cause straight because being often chronically exposed to outdoor easily wind and weather or making moist
Stream ground connection, light gas the mistaking signal even abnormal accident such as grave gas action tripping operation, have a strong impact on the safe and reliable of main transformer
, very big potential safety hazard be present in operation.
The rain cover that power system transformer substation main transformer Buchholz relay is installed at present does not have unified making standard,
Typically installed using materials such as plastics, rubber as rain cover.Because long-term exposing to the weather causes material ageing damaged, rise not
Acted on to effective rain-proof.Part rain cover is no can be completely obscured by secondary line terminal box, and rainproof effect is bad.Also portion
Point rain cover on Buchholz relay or need to be fixed on the connection method of Buchholz relay due to unreasonable structure with iron wire colligation
Lan Shang, rain cover is so caused reliably to fix, in addition the transformer flange sealing pad aging of the longer time limit of operation, flange spiral shell
Silk can not seal the generation for causing Buchholz relay permeability very well after opening.
Utility model content
The purpose of this utility model is to provide a kind of transformer Buchholz relay rain cover, by the structure for improving rain cover
And material, lift rainproof effect.
Technical scheme provided by the utility model is：
A kind of transformer Buchholz relay rain cover, including be separately mounted to Buchholz relay upper and lower part it is upper solid
Fixed rack and lower fixed support, fixed support and lower fixed support are fixed together by fixing bolt；It is described solid
Fixed rack top is provided with rain-proof baffle plate, and the rain-proof baffle plate is formed using stainless steel plate bending, and the rain-proof baffle plate surrounding is set
Downward slope is equipped with, U-shaped hole is opened up in a side wall of the rain-proof baffle plate；In fixed support is support bracket fastened with
Side is provided with rubber cushion blocks, and the rubber cushion blocks use neoprene material.
Preferably, two rubber cushion blocks are provided with the inside of upper fixed support, two rubbers are provided with the inside of lower fixed support
Rubber cushion block.
The beneficial effects of the utility model are：Transformer Buchholz relay rain-proof cover structure provided by the utility model is tight
Gather, be easily installed, fixed, cost is cheap, has good protection effect.
Brief description of the drawings
Fig. 1 is the transformer Buchholz relay rain cover general structure schematic diagram belonging to the utility model.
Fig. 2 is structural representation when the transformer Buchholz relay rain cover belonging to the utility model is inverted.
Fig. 3 is the transformer Buchholz relay rain cover decomposing schematic representation belonging to the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of transformer Buchholz relay rain cover, including rain-proof
Baffle plate 110, upper fixed support 120, fixing bolt 130, lower fixed support 140 and rubber cushion blocks 150.
Fixed support 120 and lower fixed support 140 are separately fixed at the upper and lower part of Buchholz relay, upper solid
Fixed rack 120 and lower fixed support 140 are fixed together by fixing bolt 130.Rain-proof baffle plate 110 is fixedly mounted on fixation
The top of support 120.
The rain-proof baffle plate 110 is made using 1mm stainless steels, using folding brake whole plate, considers onsite application gas
The requirement of relay size and rain-proof masked area, 40*30*8cm top rain-proof baffle plate 110 is made, connect its no-welding-seam, nothing
Point, and its trapezoidal hollow-core construction, surrounding are provided with downward slope, by increasing capacitance it is possible to increase rainproof surface, and make its top rain
Water is not easy to accumulate, and hollow-core construction reduces overall weight and materials'use, reduces financial cost, can be by Buchholz relay body and two
Secondary line is completely obscured, it is ensured that rainproof effect.A diameter of 5cm U-shaped hole 111 is offered in one side wall of the rain-proof baffle plate 110,
It is easy to secondary line to pass through.
Fixed support 120 is made using 1.5mm stainless steels, and upper fixed support 120 can be according to single floating
The specific size of ball, double ball float Buchholz relays makes, and sets 4 pin to fix cover with 1.5mm stainless steels Buchholz relay and uses 4
M8 bolts are fixedly connected.
The lower fixed support 140 is made using 1.5mm stainless steels, and lower fixed support 140 can be according to single floating
The specific size of ball, double ball float Buchholz relays makes, and sets 4 pin to fix cover with 1.5mm stainless steels Buchholz relay and uses 4
M8 bolts are fixedly connected.
Upper fixed support 120 is fixed together with lower fixed support 140 by fixing bolt 130.
Rubber cushion blocks 150 are provided with the interior survey of upper fixed support 120 and lower fixed support 140.The rubber cushion blocks
150 use 5cm neoprene materials, avoid fixed support 120 from directly being contacted with relay with lower fixed support 140, are watt
This relay test and work slot milling.Another benefit for setting rubber cushion blocks 150 is can be consolidated with even closer connection
Determine Buchholz relay top and the bottom fixed support, fix whole rain cover more firm.Rubber cushion blocks use neoprene material.
It is using chlorobutadiene as primary raw material, is formed by homopolymerization or a small amount of other monomer copolymerizations.Mainly consider its tensile strength
Height, heat-resisting, fast light, ageing-resistant performance is excellent, oil resistance is superior to natural rubber, butadiene-styrene rubber, butadiene rubber.With stronger
Flame resistance and excellent fire retardance, its chemical stability is higher, and water resistance is good.Neoprene is widely used, is such as used for
Make travelling belt and transmission belt, electric wire, the coating material of cable and resistant to chemical etching are set manufacture oil-resisting rubber hose, packing ring
Standby lining.Be applicable this utility model need install for a long time out of doors, need oil resistant, be heat-resisting, be fast light, be ageing-resistant, the performance of resistance to combustion will
Ask.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization.It can be applied to various suitable fields of the present utility model completely.For those skilled in the art,
Other modification is easily achieved.Therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
