Background technology
At present, national grid design, be configured with substantial amounts of power distribution station pole type transformer (capacity typically 400kVA with Under), this transformator is arranged on two between 2.5 meters of electric pole (highly having two kinds of 12M, 15M), its bottom shelf outage 3.4 meters about of degree, has side dress and two kinds of mounting means of formal dress.High-pressure side configures:10kV fuse, spark gap, high pressure connect electricity Cable.Low-pressure side configures:Low pressure connection cable (suspended insulated guide wire single or four core 3+1), comprehensive distribution box, 3 road low-pressure line-outgoings (insulated cable).
The pole type transformer major part using at present is all general power transformer.Including:Fuel tank, transformer oil, device body, Top cover, bushing, low-tension bushing etc., the arrangement corrugated plate radiating of fuel tank surrounding, bushing (enters line side), and low-tension bushing (goes out Line side) all design on top cover, the distance between low pressure connection cable and comprehensive distribution box are slightly larger, and cable usage amount is many;Meanwhile, Workmen climbs height more than 3.4 meters, both inconvenient, also dangerous.
Chinese patent document 201610028487.3 discloses a kind of column-type transformer, bushing (entering line side), low Gland pipe (outgoing line side) is designed into side, causes fin to reduce it is impossible to ensure enough radiatings, does not reach temperature increase requirement, easily Cause insulation ag(e)ing, reduce transformator service life.
Chinese patent document 200810120088.5 discloses a kind of whole-protection safety type transformer, and bushing (is entered Line side), low-tension bushing (outgoing line side) is designed into two sides top, and bottom also has the less fin of area of dissipation, using plug Connected mode, mainly emphasizes full protection.But the shortcoming of this patent is bushing (entering line side), low-tension bushing (outgoing line side) all exists Above fin, higher temperature can cause high and low pressure plug adnexa insulation ag(e)ing, reduces insulating properties.
Chinese patent document 201420571315.7 discloses a kind of oil-immersed type transformer of excellent heat radiation performance, and in addition this patent increases Add heat radiation oil box, improve radiating effect, but this patent shortcoming big, high cost that is volume, and low pressure wiring is inconvenient, It is not suitable for power distribution station distribution.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of pole type transformer, can solve the problem that transformation on existing post Device radiating, hermetically sealed and low-voltage lead install inconvenient, dangerous, longer with low-voltage comprehensive distribution box low pressure connection cable Problem, had both facilitated installation, maintenance, ensures safety again, can also reduce low pressure connection cable length, had economic effect well Benefit.
The technical solution of the utility model is as follows:
A kind of power distribution station pole type transformer, including fuel tank, fuel tank is the corrugated tank of rectangle, three sides outside fuel tank It is equipped with fin, top of oil-tank is provided with three bushings and gravity assisted heat pipe, and outside fuel tank, finless side is provided with Four low-tension bushings, bushing is connected with high pressure inlet wire cable, and low-tension bushing is connected with low pressure connection cable.
According to this utility model preferably, four low-tension bushings are located at the bottom of fuel tank side.Further away from each other high-voltage line, Reduce construction height, improve operational security;Simultaneously also away from radiating, be conducive to increasing the service life.
According to this utility model preferably, the number of gravity assisted heat pipe is three.
It is further preferred that three gravity assisted heat pipes and three bushings are all arranged in a linear, gravity assisted heat pipe place straight line With bushing place straight line parallel.Make full use of transformer top space, be uniformly distributed and contribute to radiating.
10kV high pressure inlet wire cable from line bar, by high-tension insulator lead to positioned at transformator (though side dress, just Dress) top bushing, the low-tension bushing output civilian electricity of 0.38/220kV by transformer pressure-reducing, positioned at transformator side Pressure, then pass through low pressure connection cable, connects comprehensive distribution box, inside comprehensive distribution box containing branch wire-outgoing breaker, metering and Capacitance compensation, the branch wire-outgoing breaker within comprehensive distribution box connects low-pressure line-outgoing cable respectively, and low-pressure line-outgoing cable leads to again Mast, is transported to user civilian for 0.38/220kV electricity, meets user power utilization and requires.
Gravity assisted heat pipe has very high heat conductivity, and its efficiency compared with the radiating of the identical copper pipe of physical dimension is up to 20 Times, structure is simple, easily manufactured, service life more than 20 years, and start-up temperature is low, and the temperature difference is bigger, and power is higher, is especially suitable for becoming Depressor radiates, and has preferable radiating effect, and the temperature rise height that running at full capacity or a small amount of load running cause, transformation can be made Device oil volume size variation, corrugated plate can meet full-sealed transformer with the change of transformer oil volume, expansion or shrinkage Service requirement, full-sealed transformer adopts corrugated tank, all-sealed structure, and corrugated siding has radiating and two kinds of functions of breathing, Corrugated siding with the change of temperature, the size of loading, the height of temperature of oil in transformer in fuel tank and automatic breathing, corrugated siding Breathing ability be more than 10,000 times it is ensured that transformer oil is completely isolated with air, without maintenance within the transformer life phase.Distribution Pole type transformer fuel tank three sides in platform area are equipped with fin, top cover is added gravity assisted heat pipe and strengthens radiating, make this device It is able to maintain that original excellent heat radiation performance effect, and reach hermetically sealed requirement.
Technical solutions of the utility model are well suited for power distribution station and run occasion, solve high-voltage lead of transformer well and exist Top, low-voltage lead is in the problem of bottom.
The beneficial effects of the utility model are:
Pole type transformer in the technical solutions of the utility model corrugated plate in three faces radiates, and has dilation function, Ensure hermetically sealed requirement, and be installed on head cover of transformer using gravity assisted heat pipe, the side radiating efficiency fall lacking fin Low problem overcomes.Low-tension bushing (a, b, c, n) is located at transformer side bottom, installs and maintenance pole type transformer low pressure connection cable Operator apart from 10kV high-voltage line farther out, be prevented effectively from high pressure Danger Electric shock risk it is ensured that construction and installation, maintainer the person peace Entirely.Simultaneously as low-tension bushing is in pole type transformer side lower part, installation and maintenance personnel's construction height decreases, and both facilitated and applies Work, makes workmen comparatively safe again.Furthermore it is also possible to reduce pole type transformer and low-voltage comprehensive distribution box low pressure connection cable Length, reduces cost.Meanwhile, the technical solution of the utility model utilizes gravity assisted heat pipe and corrugated plate radiating, so that this device is being reached While to previous security, convenience, inexpensive effect, maintain original excellent heat radiation performance effect and hermetically sealed requirement.
