Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas insulated switchgear, and particularly relates to an environmentally-friendly gas insulated metal-enclosed switchgear. BACKGROUND

[0002] In modern power systems, environmentally-friendly gas insulated metal-enclosed switchgears (hereinafter referred to as "environmentally-friendly GIS") are widely used between the power supply side and the load side of the power system as an efficient, reliable and environmentally-friendly electrical device. Such a device not only can realize the normal on-off of the circuit, but also can protect the power system and load equipment by safely breaking the current when abnormal current such as grounding and short circuit occurs. Such a gas insulated switchgear is composed of a first bushing for receiving power from a high-voltage power supply, a gas circuit breaker, a circuit breaker, a grounding switch, a movable part, a control part and the like.

[0003] Among them, the grounding switch plays a crucial role in the environmentally-friendly GIS. It not only provides grounding protection during equipment maintenance to prevent accidental electric shock from harming personnel, but also quickly connects the fault circuit to the ground to achieve rapid discharge of fault current when a grounding fault occurs. The environmentally-friendly GIS grounding switch uses environmentally-friendly insulation gas as the insulation medium, improving the safety and reliability of the device. At the same time, the design of the grounding switch also needs to consider the rapidity and high stability of the action, so as to complete the grounding operation in a short time and ensure the safety of the device and personnel.

[0004] The grounding switch used in the existing environmentally-friendly gas insulated metal-enclosed switchgear is difficult to quickly operate the opening and closing operation in actual use. The grounding switch cannot complete the opening and closing operation in a very short time, which can easily cause the arc to exacerbate the wear of the switch contacts, thereby increasing the device failure rate and other problems. Moreover, the device cannot provide stable contact pressure after the grounding switch is closed. The insufficient contact pressure after the grounding switch is closed has a probability of increasing the contact resistance, which can cause the contacts to overheat when passing through a large current, and even burn out the contacts. The safety of actual use cannot be effectively guaranteed. Therefore, the environmentally-friendly gas insulated metal-enclosed switchgear is provided by the person skilled in the art to solve the problems raised in the background art. SUMMARY

[0037] The technical environment-friendly gas insulated metal-enclosed switchgear in the embodiments of the present application will be clearly and completely described in the embodiments of the present application in combination with the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0038] As Figures 1-10As shown, the application provides: environmentally friendly gas insulated metal enclosed switchgear includes base 10, the base 10 is connected with movable contact 13 through the operating lever 14 rotatably mounted on it, the base 10 is provided with conductive assembly 12, the conductive assembly 12 is connected with the corresponding contact plate 11 of movable contact 13, the contact plate 11 and the conductive assembly 12 can be detachably connected through bolts, the mounting plate connected with movable contact 13 through bolts can be welded on the operating lever 14, the control operating lever 14 rotation can drive movable contact 13 to rotate, movable contact 13 is buckled between the contact plate 11, which can realize the closing of grounding switch, movable contact 13 is turned out from the inside of the contact plate 11, which can realize the opening of grounding switch, other components of the device and the insulating pole, ground bus, terminal structure included in the conductive assembly 12 are prior art, which will not be described here.

[0039] In order to realize the quick opening and closing effect of movable contact 13 and contact plate 11, the device further comprises adjusting module 20, elastic boost module 30 and energy storage module 40, wherein the adjusting module 20 comprises retaining frame 201 fixedly installed on base 10, a plurality of circular arc slides 202 corresponding to movable contact 13 are fixedly installed on retaining frame 201, adjusting bracket 203 is slidably installed on circular arc slide 202, elastic boost module 30 is slidably installed on adjusting bracket 203, L-shaped baffle 15 is fixedly installed on one side of movable contact 13, L-shaped baffle 15 is used to provide upward thrust for elastic boost module 30 during the rotation of movable contact 13 following operating lever 14 to close, elastic boost module 30 is used to provide extrusion force for L-shaped baffle 15 when movable contact 13 is closed with contact plate 11, correspondingly, energy storage module 40 comprises energy storage mechanism 401 and actuating mechanism 402 rotatably installed on adjusting bracket 203, actuating mechanism 402 is used to provide rotating motion trend for energy storage mechanism 401 when elastic boost module 30 moves upward, energy storage module 40 is used to pull elastic boost module 30 to store energy when it is rotated from horizontal to vertical state.

[0040] When performing the grounding switch closing operation of the environmentally friendly gas-insulated metal-enclosed switchgear, the adjusting bracket 203 and its bottom-mounted elastic booster module 30 and energy storage module 40 move to the rotation path of the moving contact 13. During the rotation of the moving contact 13 controlled by the lever 14, the L-shaped baffle 15 on one side of the moving contact 13 pushes the elastic booster module 30 upwards within the adjusting bracket 203. As the elastic booster module 30 moves upwards, it drives the energy storage mechanism 401 to rotate via the actuating mechanism 402. The rotating energy storage mechanism 401 drives the elastic booster module 30 to store energy. When the moving contact 13 and the L-shaped baffle... When plate 15 rotates to the front end of elastic booster module 30, moving contact 13 approaches contact plate 11. Energy storage mechanism 401 resets and controls elastic booster module 30 to move downward. At the same time, the elastic pressure of elastic booster module 30 itself is released, which can provide rapid boost to L-shaped baffle 15 at its front end, thereby achieving the effect of rapid closing of moving contact 13 and contact plate 11. When moving contact 13 and contact plate 11 are fully closed, elastic booster module 30 itself still has a certain elastic pressure, which can provide squeezing force to L-shaped baffle 15 at its front end, achieving stable contact between moving contact 13 and contact plate 11, which is beneficial to improving the reliability and service life of equipment.

[0041] When performing the grounding switch opening operation of the environmentally friendly gas-insulated metal-enclosed switchgear, the adjusting bracket 203 can be controlled to slide on the arc-shaped slide 202, moving the adjusting bracket 203 and its connected elastic boosting module 30 and energy storage module 40 to the other side of the L-shaped baffle 15. During the rotation and movement of the elastic boosting module 30 along the path of the arc-shaped slide 202, the front end of the elastic boosting module 30 abuts against the L-shaped baffle 15, wherein the side of the L-shaped baffle 15 away from the moving contact 13 is an arc surface, which facilitates the elastic boosting... The movement of the front end of the push module 30 ensures that the elastic push module 30 always maintains a certain amount of stored energy. When the front end of the elastic push module 30 rotates 180° completely, it releases its elastic potential energy from the arc surface, which can provide a rapid reverse thrust for the L-shaped baffle 15, thereby achieving the effect of rapid opening of the moving contact 13 and the contact plate 11. Then, the operating lever 14 is used to control the rotation of the moving contact 13 to restrict it to a safe opening position. The closing and opening operations of the grounding switch can be carried out quickly, which can effectively avoid the generation of electric arc.
