Description
Technical field
The invention belongs to field transformer, relate to a kind of high overload distribution transformer.
Background technology
Distribution transformer, is called for short " distribution transforming ".Distribution transformer, refers in distribution system
The one transmitting AC energy according to law of electromagnetic induction conversion alternating voltage and electric current is quiet
Only electrical equipment.China power transformer product by electric pressure generally can be divided into extra-high voltage (750KV and
Above), supertension (500KV) transformator, 220-110KV transformator, 35KV and following
Transformator.Distribution transformer typically refers to operate in electric pressure in power distribution network
10-35KV, capacity are 6300KVA and the power transformer powered to terminal use directly below
Device.
Along with deepening continuously of China's " saving energy and reduce the cost " policy, country encourages development energy-conservation
Type, low noise, intelligentized distribution transformer product.Part high energy consumption at network operation
Distribution transformer has not met industry development trend, is faced with technology upgrading, update
Demand, following will progressively be taken by energy-conservation, material-saving, environmental protection, the transformator of low noise
Generation.
The use of distribution transformer is also affected by the restriction of environment, such as temperature, height above sea level,
Humidity etc..The use temperature of general oil-filled transformer is that ambient temperature is not higher than
40 DEG C, it is not less than-25 DEG C, for low temperature environment, owing to transformator operationally can produce
Heat, therefore can well adapt to low temp area, but be not precluded within some areas and occur
Extreme microthermal climate, can make the cooling oil in transformator freeze when there is extreme low temperature,
Iron core and copper cash can be impacted by low temperature, cause the performance of distribution transformer to be affected；
If improving high-power transformer, required input cost for extreme microthermal climate merely
Height, uneconomical；The most existing transformator in order to prevent casing by rainwater drench corrosion and
Using rain shade to break off relations this problem, existing rain shade all uses the upper surface of casing
Cover and within it solve this problem, cause the air stream of the casing periphery when fair weather
Logical not smooth, affect the radiating effect of fin on casing.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, it is proposed that a kind of
High overload distribution transformer, present invention solves the technical problem that it is to improve distribution transformer
Performance and can prevent rainwater from getting on distribution transformer, and can also be by unnecessary rainwater collection
Collection gets up.
The purpose of the present invention can be realized by following technical proposal:
A kind of high overload distribution transformer, the iron core including housing, being arranged in housing and
The fuel tank connected with housing, iron core uses three-phase four frame pentastyle structure, including four solely
