Problems solved by technology

It solves the problem that the general vacuum circuit breaker is airtight, and it is difficult to overhaul the internal vacuum interrupter and observe whether the internal vacuum state is damaged
This utility model is to observe whether the vacuum interrupter is airtight through the change of the color of the colored gas in the confined space, and there is no way to find out the reason for the frequent suppression of the hydraulic mechanism

Embodiment 1

[0044] Such as figure 1 As shown, a circuit breaker hydraulic mechanism repair oil tank includes a fuel tank body 1 and a connecting flange 2. The fuel tank body is made of plexiglass and has good transparency, chemical stability, mechanical properties and weather resistance. The upper part of the fuel tank body is open, the flange 2 is located on the top of the fuel tank body 1 , and the flange 2 is integrated with the fuel tank body 1 .

[0045] The maintenance oil tank is light in weight, high in strength, transparent and easy to observe, and can be easily installed. Because the fuel tank body 1 of the maintenance fuel tank is transparent, each internal component can be clearly seen from the outside, and the working method of directly finding defects and eliminating defects. For example, the existence of bubbling and pressure relief can be easily found, without the need to disassemble and inspect all high-pressure pipes of the pressure mechanism inside the fuel tank, savin...

Embodiment 2

[0062] The structure and method of this embodiment and the first embodiment are basically the same, the difference is that: the fuel tank body 1 and the connecting flange 2 are made of tempered glass, which has high strength, strong impact resistance and good thermal stability.

Embodiment 3

[0064] The structure and method of this embodiment and the first embodiment are basically the same, the difference is that: the fuel tank body 1 and the connecting flange 2 are made of transparent glass fiber reinforced plastic, and the transparent glass fiber reinforced plastic is completely soaked with resin, without adding any It is produced without filler, which is transparent in appearance, and has the advantages of light weight, high mechanical strength, good insulation, and corrosion resistance.

Abstract

The invention discloses a breaker hydraulic mechanism overhaul oil tank and a method for searching frequent pressing of a hydraulic mechanism using the breaker hydraulic mechanism overhaul oil tank. The breaker hydraulic mechanism overhaul oil tank comprises an oil tank body and a connecting flange, the oil tank body is made of a transparent material, the upper portion of the oil tank body is provided with an opening, the connecting flange is located on the periphery of the top of the oil tank body, and the connecting flange and the oil tank body are combined to form an integrated structure. According to the method for searching frequent pressing of a hydraulic mechanism using the breaker hydraulic mechanism overhaul oil tank, when the hydraulic mechanism is loaded with pressure, all elements in the hydraulic mechanism can be checked with naked eyes, defects can be directly searched for, key parts are subjected to key troubleshooting, the defects are eliminated, a large amount of timeis saved, and the overhauling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of fault detection of a high-voltage circuit breaker, in particular to a circuit breaker hydraulic mechanism maintenance oil tank and a method for searching frequently suppressed hydraulic mechanisms using the oil tank. Background technique [0002] The rapid development of social economy has led to the continuous improvement of the requirements for the power system, and the demand for energy is also increasing, which puts forward stricter requirements for the stability and economy of the power system. [0003] A power circuit breaker is a breaking device for power lines. The hydraulic mechanism of the power circuit breaker is the main part of the opening and closing of the power circuit breaker. The hydraulic mechanism of the circuit breaker is in a high hydraulic state when it is working, so it is prone to oil leakage from the high-pressure pipeline, resulting in frequent pressure on the hydraulic mechanism of the ...
