Description
Technical field
The utility model relates to transformer technology field, particularly a kind of protective device of oil-filled transformer.
Background technology
Along with the development of power industry, transformer is also along with continuous development, in order to reduce manufacturing cost, generally use oil-filled transformer more, transformer oil is full of in transformer mailbox, but because the reason such as poorly sealed is very easily made moist, exchange of moisture in air is in oil, accelerate oil deterioration speed, time one is long, and the performance of transformer oil can be made to reduce, and serious has threatened the cycle of operation of transformer, and transformer in the past seldom has the ability of rainwater-proof and dust, rainwater or dust is often allowed to enter in the fuel tank of transformer.
Summary of the invention
The purpose of this utility model is just to provide a kind of protective device of oil-filled transformer, and structure is simple, easy for installation and also enhance the sealing property of transformer-cabinet, has and prevents rainwater or dust from entering into beneficial effect in the fuel tank of transformer.
Technical problem of the present utility model is solved mainly through following technical proposals:
A kind of protective device of oil-filled transformer, comprise oil tank of transformer and case lid, sealing ring is provided with between described oil tank of transformer and case lid, and in transformer oil in oil tank of transformer, be placed with the device body of transformer, described case lid top is evenly provided with strip reinforced sheet along the sidewall of oil tank of transformer, often organize reinforced sheet both sides and be respectively equipped with bolt, described bolt is from top to bottom successively through reinforced sheet, case lid and aforementioned seal circle, and be fixed on the sidewall of oil tank of transformer, the edge of described case lid all forms kink to downward-extension, described oil tank of transformer side is provided with fin, narrow end bottom this oil tank of transformer is connected with fixed support, middle, described sealing ring upper and lower both sides is respectively equipped with a sealing strip arranged along sealing ring length.
Preferably, described sealing strip is isosceles triangle shape, bottom described case lid and the top side wall of oil tank of transformer be respectively equipped with the upper seal groove corresponding with two sealing strips upper and lower in sealing ring and lower seal groove cavity, two bolts on described reinforced sheet are individually fixed on the sidewall of the oil tank of transformer of lower seal groove cavity both sides.
Preferably, described sealing ring width is greater than oil tank of transformer sidewall thickness, and the madial wall of described kink is provided with the groove of corresponding sealing ring.
Preferably, described sealing ring and sealing strip are integrated setting.
Preferably, four angles of described case lid are equipped with radian.
The beneficial effects of the utility model are: the utility model strengthens the sealing effectiveness between case lid and casing, can prevent air or moisture from entering in casing, thus accelerate the problem of rate of deterioration of transformer oil, and can also rainwater-proof and dust; There is structure simple, feature easy for installation, and the sealing property also enhancing transformer-cabinet, have and prevent rainwater or dust from entering into beneficial effect in the fuel tank of transformer.
