Abstract
The utility model relates to a pressure releasing device of a transformer. The pressure releasing device comprises a transformer oil tank, wherein a pressure releasing valve is installed outside the top of the transformer oil tank through a pipeline which is communicated with the inside of the transformer oil tank, an outlet of the pressure releasing valve is horizontally connected with an oil guiding pipe through a connection flange, the oil guiding pipe is bent straight down for 90 DEG along the side wall of the transformer oil tank from the connection part, a fixing sheet is fixedly installed on the side wall of the transformer oil tank, and the fixing sheet is used for fixing a U-shaped hoop surrounding the oil guiding pipe through a bolt. The pressure releasing valve is installed on the transformer body, so that the pressure inside the transformer oil tank is reduced, the danger caused by the large pressure inside the oil tank of the transformer can be reduced, the ejected oil along the pressure also can be recycled to a transformer oil pool, and the recycling of the resource is realized.
Description
Technical field
The utility model belongs to generating, power transformation and distribution technique field, particularly a kind of transformer pressure relief device.
Background technology
Transformer is one of device important in transformer station, in electric power system, plays an important role.Under usual conditions, transformer oil temperature in when operation oil tank of transformer can raise, and along with temperature raises, the pressure in oil tank of transformer can increase thereupon, and therefore, deep fat enters fin along cooling pipe and carries out oily circulating cooling.But the transformer-cabinet internal pressure is excessive in some cases, move in this case for a long time, can affect the sealing of transformer-cabinet, shorten the life-span of transformer, and bring potential safety hazard to operation, maintainer.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of transformer pressure relief device is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of transformer pressure relief device, comprise oil tank of transformer, top outer at oil tank of transformer, by the pipeline setting pressure relief valve with the oil tank of transformer internal communication, the earth pressure release valve outlet port is by mounting flange and oil-piping layout level connection joint, and oil-piping layout is crooked 90 degree after connecting portion, prolong the oil tank of transformer sidewall vertically downward, be fixedly mounted with stator on the oil tank of transformer sidewall, stator will be fixed around the U-shaped anchor ear of oil guide pipe by bolt, in order to the fixing position of oil guide pipe.
And the relief pressure value that described pressure relief valve is set is the upper limit extreme value that oil tank of transformer sets.
And the described oil guide pipe fixture consisted of stator, bolt and U-shaped anchor ear has two covers, a set of oil tank of transformer side wall upper part that is installed on, the another set of oil tank of transformer lower sidewall that is installed on, the distance between two cover oil guide pipe fixtures is greater than 30cm.
Advantage of the present utility model and good effect are
The utility model is by setting pressure relief valve on transformer body, thereby the pressure in the reduction oil tank of transformer, alleviate the danger of transformer because of the excessive generation of tank pressure, the oil with the pressure ejection can be recycled to the transformer oil sump simultaneously, realized the recycling of resource.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described, following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of transformer pressure relief device, as shown in Figure 1, comprise oil tank of transformer 1, top outer at oil tank of transformer, by the pipeline setting pressure relief valve 2 with the oil tank of transformer internal communication, the earth pressure release valve outlet port is by mounting flange 3 and oil-piping layout 4 level connection joints, oil-piping layout is crooked 90 degree after connecting portion, prolong the oil tank of transformer sidewall vertically downward, be fixedly mounted with stator 5 on the oil tank of transformer sidewall, stator will be fixing around the U-shaped anchor ear 7 of oil guide pipe by bolt 6, in order to the fixing position of oil guide pipe.
In concrete enforcement of the present utility model, the relief pressure value that described pressure relief valve is set is the upper limit extreme value that oil tank of transformer sets.
In concrete enforcement of the present utility model, the described oil guide pipe fixture consisted of stator, bolt and U-shaped anchor ear has two covers, a set of oil tank of transformer side wall upper part that is installed on, the another set of oil tank of transformer lower sidewall that is installed on, the distance between two cover oil guide pipe fixtures is greater than 30cm.
