Side-opening door oil tank for high-voltage unit

Abstract

The invention discloses a side-opening door oil tank for a high-voltage unit. The oil tank comprises a tank body, a framework is arranged in the tank body, a door frame is arranged on one longitudinal side of the tank body, a door is connectedly mounted on the door frame, and a translation device is arranged at the inner bottom of the tank body; the oil tank further comprises a movable carrying device which is arranged outside the tank body. The side-opening door oil tank is easy to mount and dismount, and lifting equipment is not required in the whole process; a person needs not to enter the oil tank at all, and can enter the oil tank conveniently after the internal high-voltage unit is drawn out even if needing to enter the oil tank; although being researched for high-voltage test, the device can be applied to occasions as long as a device needs to be immersed into the oil tank and an water tank, thereby being multipurpose.

Description

technical field [0001] The invention relates to an oil tank for accommodating high-voltage equipment such as a transformer and a Max generator in a high-voltage test, in particular to a side-opening door oil tank. Background technique [0002] In the high-voltage test and the operation of high-voltage equipment, in order to meet the requirements of use, some high-voltage generating devices, such as transformers, impulse voltage generators, Max generators, pulse forming networks, etc., need to be placed in a large box. The interior is filled with transformer oil as an insulating medium. For the design of the fuel tank, according to the current situation, most of them are designed to open the top. This method of adding a "cover" to the "box" is in line with people's traditional thinking, but in practical applications, the shortcomings are obvious. [0003] First, the weight of the high-voltage generating device is usually very large. Taking a transformer as an example, the w...

Problems solved by technology

In some venues that lack hoisting equipment or space is limited, it is very difficult to hoist the transformer out for maintenance once. If hoisting out and hoisting in frequently, the process will be more cumbersome

[0004] Second, some fuel tanks are designed to avoid frequent lifting of the high-pressure device. The method adopted is that people enter the interior of the fuel tank to maintain the device. This method must leave enough room for people to operate inside the high-pressure device. A sufficient distance, at least 50 centimeters, will increase the volume of the oil tank and require more transformer oil, and people must wear oil-proof clothing when entering and leaving

[0005] Third, during operation, if some bolts and nuts accidentally fall into the fuel tank, because the internal equipment is complex and the light is not good, these metal objects are not easy to be found and taken out, causing problems with the insulation of the equipment, or even damage

[0009] Apparently, neither has a substantial improvement in terms of ease of assembly
