Embodiment

[0016] A transformer such as figure 1 As shown, it includes a coil frame 1 wound with a coil, and a magnetic core placed in the central through hole of the coil frame 1 . The oil-immersed transformer also includes a transformer casing 2, a rain gutter 3 connected to the top of the transformer casing 2, and a water pump 4 for extracting rainwater in the rain gutter 3. After the rainwater effect is completed, the water pump 4 can be used to pump out the water, so as to avoid the gasification and expansion of the water in the air bag 5 and cause the air bag 5 to explode, so that the water flows out, and the water conduction affects the working stability of the oil-immersed transformer. And the water pump 4 recycles the water and can use it in other places, thereby saving resources. Two vents 12 are integrally formed symmetrically on the side wall of the transformer case 2. The vents 12 can realize the air flow inside the transformer case 2, thereby achieving the purpose of reduc...

Abstract

The invention relates to a transformer. The transformer comprises a coil frame wound with a coil, and a magnetic core placed in a central through hole of the coil frame, and also comprises a transformer shell and a rain groove connected with the top end of the transformer shell; ventilating openings are formed in the side wall of the transformer shell; a gasbag is horizontally connected in the side wall of the transformer shell, and the gasbag is connected with the rain groove; an oil storage tank matched with the gasbag is also included in the transformer shell; the oil storage tank is connected with an oil inlet of the oil immersed transformer; a piston is vertically and glidingly matched with the inner wall of the oil storage tank; and the piston is in contact with the gasbag through apush rod. By adoption of the scheme, corresponding emergency processing can be performed on the oil immersed transformer, so that the oil immersed transformer can perform normal and stable operation;and in addition, manual refueling in a rainy day is not needed, so that labor intensity is lowered.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a transformer. Background technique [0002] The transformer is composed of a primary coil and a secondary coil wound sequentially on a single bobbin, and the core is bonded to the bobbin through the through holes of the bobbin. The oil in the transformer mainly plays the role of 1. heat dissipation and cooling during operation; 2. insulation and insulation maintenance for windings (maintain good insulation state); 3. transformer oil plays arc suppression at the high voltage lead wire and the contact point of the tap changer role, to prevent the generation of corona and arc discharge. [0003] Due to the humid air in rainy days, it is easy to cause water in the oil during the transportation of oil drums and refueling process. After entering the water, the insulation performance of the transformer oil will be reduced, which will easily cause safety hazards. Normal and stable ...
