Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gas insulated metal-enclosed switchgear, particularly relates to a box type gas insulated metal-enclosed switchgear. BACKGROUND

[0002] The gas insulated metal-enclosed switchgear is a metal-enclosed switchgear and control device which uses a gas with a pressure higher than atmospheric pressure as an insulating medium for at least a part thereof. The principle is to insulate the metal conductor with a gas with high insulation performance (such as SF6 or a mixture thereof), and to isolate the electrical equipment from the external environment through a metal-enclosed structure to prevent dust, moisture and the like from damaging the equipment, thereby improving the reliability and safety of the equipment. However, the conventional gas insulated metal-enclosed switchgear still has some problems in use.

[0003] When the gas insulated metal-enclosed switchgear is used for a long time, the internal insulation material and components are prone to discharge and breakdown due to aging, thereby generating electric arc to convert electrical energy into heat energy, causing the temperature and pressure of the surrounding air to rise sharply and leading to explosion of the gas insulated metal-enclosed switchgear. Since the gas insulated metal-enclosed switchgear is sealed, the pressure generated during the explosion cannot be quickly discharged, so that the power of the explosion is greater. Therefore, a box type gas insulated metal-enclosed switchgear is needed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a box type gas insulated metal-enclosed switchgear to solve the problem that the internal pressure of the conventional gas insulated metal-enclosed switchgear cannot be quickly and safely discharged during explosion.

[0005] To solve the above technical problems, the utility model provides the following technical scheme: a box type gas insulated metal-enclosed switchgear, comprising a switchgear and a control panel, wherein the front end of the switchgear is provided with the control panel, the top end of the switchgear is provided with a pressure relief structure, the bottom end of the switchgear is provided with a base, the bottom end of the base is provided with an anti-rust structure, and the pressure relief structure comprises a sealing plate, a sealing ring, a fixed block, a slot, a plug, a mounting groove and a clamping block.

[0006] Preferably, one end of the plug is inserted into the slot, and the plug and the slot form an insertion structure.

[0007] Preferably, the springs are provided in two sets, and the springs and the insert block form a telescopic structure.

[0008] Preferably, the insert block is provided in two sets, and the two sets of insert blocks are symmetrically arranged on one side of the card block.

[0009] Preferably, the sealing ring is sleeved on the outer side of the bottom end of the sealing plate, and the sealing plate and the sealing ring form a sealing structure.

[0010] Preferably, the rust-proof structure includes a base plate, a fixed seat, and a rotating rod. The fixed seat is fixed to the bottom end of the base, and the rotating rod is installed inside the fixed seat. The bottom end of the rotating rod is fixed to the base plate.

[0011] Preferably, the outer side of the rotating rod is provided with an external thread, and the inner side of the fixed seat is provided with an internal thread, forming a threaded connection between the rotating rod and the fixed seat.

[0012] The advantages of the box-type gas-insulated metal-enclosed switchgear provided by this utility model are as follows:

[0013] By incorporating a pressure relief structure, a sealed connection can be formed through the cooperation of the sealing plate and sealing ring. This ensures that the sealing plate, installed at the top of the switchgear, will not leak. Furthermore, through the cooperation of the insert block and spring, the insert block can be inserted into the slot to slightly fix the sealing plate. In the event of an explosion inside the switchgear, the pressure can be directly forced open to release the pressure, reducing the explosive force of the explosion. The pressure relief port is located at the top of the switchgear, making pressure relief safer and thus improving overall safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a box-type gas-insulated metal-enclosed switchgear, such as Figures 1-6 As shown, it includes a switchgear 1 and a control panel 2. The control panel 2 is installed at the front end of the switchgear 1, a pressure relief structure 3 is provided at the top of the switchgear 1, a base 4 is installed at the bottom of the switchgear 1, and a rust-proof structure 5 is provided at the bottom of the base 4.

[0023] In a further preferred embodiment of this utility model, such as Figures 1-6 As shown: The pressure relief structure 3 includes a sealing plate 301, a sealing ring 302, a fixing block 303, a slot 304, a plug 305, a mounting groove 307, and a locking block 308. The sealing plate 301 is installed on the top of the switchgear 1, and the sealing ring 302 is installed on the outer side of the bottom end of the sealing plate 301. The fixing block 303 is fixed to both sides of the top of the switchgear 1, and the locking block 308 is installed inside the fixing block 303. One side of the locking block 308 is fixed to one side of the sealing plate 301. The mounting groove 307 is opened inside both sides of the locking block 308, and a spring is installed inside the mounting groove 307. Spring 306, with a plug 305 fixed on one side of spring 306, slot 304 opened on both sides inside fixed block 303, one end of plug 305 inserted into slot 304, plug 305 and slot 304 forming an insertion structure, spring 306 is provided in two sets, spring 306 and plug 305 forming a telescopic structure, plug 305 is provided in two sets, the two sets of plug 305 are symmetrically located on one side of locking block 308, sealing ring 302 is sleeved on the outer side of bottom end of sealing plate 301, sealing plate 301 and sealing ring 302 forming a sealing structure.

[0024] Specifically, when using the switchgear 1, the sealing ring 302 is fitted onto the bottom end of the sealing plate 301, and then the bottom end of the sealing plate 301 is inserted into the top end of the switchgear 1. When the sealing plate 301 is installed on the top end of the switchgear 1, the locking block 308 will be inserted into the interior of the fixing block 303. When inserted, one end of the insert block 305 will be pushed into the interior of the slot 304 by the spring 306. Since the insert block 305 is pushed into the interior of the slot 304 by the spring 306, it is easy to open the sealing plate 301 when it is pushed upward. In the event of an explosion inside the switchgear 1, the pressure can be directly pushed open by the sealing plate 301 to release the pressure, making the explosion less powerful. Furthermore, the pressure relief port is located at the top end of the switchgear 1, making it safer during pressure relief, thereby improving safety.

[0025] In a further preferred embodiment of this utility model, such as Figures 1-6 As shown: The rust-proof structure 5 includes a base plate 501, a fixed seat 502 and a rotating rod 503. The fixed seat 502 is fixed to the bottom end of the base 4. The rotating rod 503 is installed inside the fixed seat 502. The bottom end of the rotating rod 503 is fixed to the base plate 501. The outer side of the rotating rod 503 is provided with external threads, and the inner side of the fixed seat 502 is provided with internal threads. The rotating rod 503 and the fixed seat 502 form a threaded connection.

[0026] Specifically, when placing the switchgear 1, the position of the rotating rod 503 inside the fixed seat 502 is adjusted by rotating the base plate 501, thereby adjusting the height of the bottom of the switchgear 1 so that the bottom does not directly contact the ground when placed, making it less likely for the bottom of the switchgear 1 to rust when placed for a long time, thus completing the rust prevention work.
