Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 A vacuum oiling machine with automatic oil level control is shown, which has an oil tank 1, and the top of the oil tank 1 is sequentially provided with an oil inlet pipe 2, a gear pump 3, an oil outlet pipe 4, a precision filter 5 and a vacuum pump 6, and the oil inlet pipe 2. The gear pump 3, the oil outlet pipe 4, and the vacuum pump 6 are connected to the oil tank 1 respectively. An oil injection conversion device is arranged between the oil inlet pipe 2 and the gear pump 3. The oil tank 1 is mounted on the vehicle frame 7, and the vehicle frame The bottom of 7 is provided with a roller 8, and a liquid level sensor 9 is provided on the pipeline of the oil inlet pipe 2. The liquid level sensor 9 is connected with the electromagnetic valve of the switch of the oil inlet pipe 2. When the oil in the oil injection machine ...

Abstract

A vacuum oil filling machine capable of automatically controlling oil level is provided with an oil tank, wherein an oil inlet pipe, a gear pump, an oil outlet pipe, a precision filter and a vacuum pump are sequentially arranged at the top of the oil tank, the oil inlet pipe, the gear pump, the oil outlet pipe and the vacuum pump are communicated with the oil tank, and an oil filling conversion device is arranged between the oil inlet pipe and the gear pump. The vacuum oil filling machine is characterized in that the oil tank is erected on a frame, rolling wheels are arranged at the bottom of the frame, and a liquid level sensor is arranged on the oil inlet pipe and is connected with a magnetic valve of a switch of the oil inlet pipe. When oil in the oil filling machine reaches the position sensed by the liquid lever sensor, the liquid lever sensor controls the magnetic valve of the switch of the oil inlet pipe connected with the liquid lever sensor to be closed, and the purpose of automatic oil level control is achieved.

Description

technical field [0001] The invention relates to a vacuum oiling machine, in particular to a vacuum oiling machine with automatic oil level control. Background technique [0002] During the use of outdoor high-voltage current transformers or voltage transformers, as the use time increases and the seasons change, the oil level of the insulating oil inside will drop, and it needs to be filled with oil regularly. For such a small amount of oil injection, if the existing ordinary oil injection equipment is used to inject oil from the oil injection port at the bottom of the current transformer or voltage transformer, the oil will be in contact with the air, which will easily generate air bubbles, which will increase the gas content and water content in the oil. As a result, the insulation level of the oil is reduced, and insulation accidents are likely to occur when air bubbles enter the coils of the transformer; and if the oil is injected from the top opening of the outdoor high-...
