Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] A monitoring system for single-phase oil-immersed transformers, such as Figure 5As shown, it includes an acquisition unit 6, an execution unit 8 and a main control unit 7. The acquisition unit 6 collects the internal information of the transformer and transmits it to the main control unit 7. The main control unit 7 processes the collected information and transmits the execution instruction to the execution unit 8. The execution unit 8 executes the instruction; the execution unit 8 is a switch valve group, the switch valve group includes a main switch and N auxiliary switches, the main switch and N auxiliary switches are connected in series, and the N auxiliary switches are connected in...

Abstract

The invention provides a single-phase oil-immersed transformer and a monitoring system thereof. The system comprises an acquisition unit, an execution unit and a master control unit, wherein the acquisition unit acquires information inside the transformer and transmits the information to the master control unit, the master control unit performs processing according to acquired information and transmits an execution instruction to the execution unit, and the execution unit executes the execution instruction. The system can effectively avoid the flashover accident caused by condensation formed due to severe temperature and humidity effects. The transformer further comprises a lifting mechanism, a power mechanism and an oil tank, wherein the lifting mechanism is arranged under the iron core, the power mechanism is connected with the lifting mechanism, and the oil tank is connected with the power mechanism and is arranged outside the box body. The single-phase oil-immersed transformer can use oil in the box body as a power source through the power mechanism, drives the lifting mechanism to take out the iron core, stores the oil in the box body to the oil tank, facilitates iron core maintenance and oil change operation, saves the cost and also improves the overhaul efficiency.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a single-phase oil-immersed transformer and a monitoring system thereof. Background technique [0002] The main components of the transformer are iron core and coil, and the iron core plays the role of magnetic conduction and skeleton in the transformer, and its processing quality directly affects the quality of the transformer. At present, transformer iron cores generally adopt laminated iron core structure, which is different from the manufacture of small transformer iron cores in the manufacturing process, mainly reflected in the stacking and lifting methods of iron cores. Transformer iron cores generally only need to be placed on the working platform After the stacking is completed, it can be lifted directly from the working platform with a sling so that it can be changed from a horizontal position to a vertical position. During the lifting process, it is...
