Description

Technical Field

[0001] The present invention relates to the field of energy, and in particular to an energy storage system of a user-side energy storage power station. Background Art

[0002] The vacuum interrupter, also known as the vacuum switch tube, is the core component of the medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off from the power supply through the excellent insulation of the vacuum in the tube. The vacuum interrupter is mainly composed of an airtight insulating shell, a conductive circuit, a shielding system, contacts, bellows and other parts. When the moving and static conductive rods are disconnected, the contacts on the moving and static conductive rods in the shielding system will generate an arc, which will generate a lot of heat and is not easy to dissipate in time. Over time, it will affect the practical efficiency and life of the interrupter. The shielding system is made of metal. If it is directly cooled by coolant, leakage will occur.

[0040] The cooling part 300 includes two interconnected cooling channels 1 330, a cooling channel 2 340, a push plate 1 331 arranged in the cooling channel 1 330, and a push plate 2 341 elastically arranged in the cooling channel 2 340, and the push plate 1 331 is fixedly connected to the dynamic drive shaft 210, the cooling channel 1 330 is located outside the cavity 110, the cooling channel 2 340 is located between the shielding tube 120 and the inner wall of the cavity 110, and a coolant is provided between the push plate 1 331 and the push plate 2 341; wherein,

[0041] The driving shaft 210 drives the moving conductive rod 130 to move downward, and the driving shaft 210 moves downward from the top of the waist-shaped hole 150 until the moving conductive rod 130 contacts the static conductive rod 140, and the elastic mechanism pushes the driving shaft 210 to move the driving shaft 210 to the top of the waist-shaped hole 150; the push plate pushes the coolant into the cooling channel 1 330 to maintain the insulation between the shielding tube 120 and the cooling channel 2 340;

[0042] When a short circuit occurs in the arc extinguishing chamber 100, the dynamic conductive rod 130 moves upward and disconnects from the static conductive rod 140, and the bottom end of the waist-shaped hole 150 moves upward and contacts the drive shaft 210 to generate a time difference, so that the arc generated in the arc extinguishing chamber 100 disappears, and then the bottom end of the waist-shaped hole 150 pushes the drive shaft 210 to move upward, and the drive shaft 210 drives the push plate 1 331 to move and squeeze the coolant into the cooling channel 2 340 to cool the shielding tube 120.

[0043] Interrupter 100

[0044] The arc extinguishing chamber 100 is suitable for extinguishing arcs and suppressing current after quickly cutting off power in a circuit.

[0045] The arc extinguishing chamber 100 includes a cavity 110, a shielding tube 120 disposed in the cavity 110, a dynamic conductive rod 130 slidably disposed in the shielding tube 120, and a static conductive rod 140 fixed in the shielding tube 120, wherein the dynamic conductive rod 130 is provided with a waist-shaped hole 150. The arc extinguishing chamber 100 also includes a dynamic end cover plate 160 and a static end cover plate 170 connected to the shielding tube 120, wherein the dynamic end cover plate 160 and the static end cover plate 170 are respectively located at the upper and lower ends of the cavity 110; the dynamic conductive rod 130 is slidably disposed on the dynamic end cover plate 160, and the static conductive rod 140 is fixed on the static conductive rod 140. The dynamic end cover plate 160 is also provided with a guide tube 180, and a bellows 190 is fixed on the guide tube 180, wherein the guide tube 180 is sleeved on the dynamic conductive rod 130, and the other end of the bellows 190 is arranged against the shielding tube 120. The moving conductive rod 130 and the stationary conductive rod 140 are both provided with a contact 141. The guide tube 180 limits the moving direction of the moving conductive rod 130, making the moving direction of the moving conductive rod 130 more stable. The contact 141 is the part where the arc is generated and extinguished. The bellows 190 ensures that the moving conductive rod 130 and the stationary conductive rod 140 move within a certain range and ensures the vacuum state of the arc extinguishing chamber 100.

[0046] Driving unit 200

[0047] The driving unit 200 is suitable for driving the moving conductive rod 130 to contact the stationary conductive rod 140 .

[0048] The driving part 200 includes a driving shaft 210 slidably disposed in the waist-shaped hole 150 and an elastic mechanism elastically connected to the driving shaft 210, and the driving shaft 210 drives the moving conductive rod 130 to contact the static conductive rod 140 to maintain the connection of the circuit. The driving part 200 includes a support frame 230, a fixing frame 240 fixed on the support frame 230, a rotating shaft 250 rotatably disposed on the fixing frame 240, a guide plate 260 fixed on the rotating shaft 250, and a guide groove 261 provided on the guide plate 260, wherein the driving shaft 210 is fixed on the driving disk, and the driving disk is slidably disposed in the guide groove 261; the guide groove 261 is an arc groove, so that the driving groove can drive the driving shaft 210 to move up and down. The rotating shaft 250 drives the guide plate 260 to rotate. Since the guide groove 261 on the guide plate 260 is adapted to the driving disk, the guide groove 261 drives the driving disk to move in the guide groove 261. The guide groove 261 is an arc groove, so that the driving disk produces a vertical displacement. Since the driving disk is fixedly connected to the driving shaft 210, the driving shaft 210 is slidably arranged in the waist-shaped hole 150, so that the conductive rod 130 can be driven to move up and down.

[0049] In order to achieve the time-delay effect, a sleeve 270 sleeved on the moving conductive rod 130 is fixed to one end of the driving shaft 210, and a fixing plate 271 is fixed to the bottom end of the sleeve 270, wherein one end of the elastic mechanism abuts against the fixing plate 271, and the other end abuts against the copper bar 280 arranged on the side wall of the support frame 230. The elastic mechanism is a spring 1 220. The driving shaft 210 slides in the waist-shaped hole 150, and the driving shaft 210 contacts the bottom end of the waist-shaped hole 150, and then drives the moving conductive rod 130 to move downward. When the moving conductive rod 130 contacts the static conductive rod 140, the spring 1 220 can press the fixing plate 271 upward, and the fixing plate 271 drives the sleeve 270 to move upward, and the sleeve 270 drives the driving shaft 210 to move upward, so that the driving shaft 210 is located at the top of the waist-shaped hole 150. When a short circuit occurs in the arc extinguishing chamber 100, the movable conductive rod 130 moves upward and disconnects from the static conductive rod 140, and the bottom end of the waist-shaped hole 150 moves upward and contacts the driving shaft 210, during which a time difference is generated so that the arc in the arc extinguishing chamber 100 can disappear during this period.

[0050] Cooling unit 300

[0051] The cooling unit 300 is suitable for cooling the high temperature generated in the arc extinguishing chamber 100 .

[0052] The cooling part 300 includes two interconnected cooling channels 1 330, cooling channel 2 340, a push plate 1 331 disposed in the cooling channel 1 330, and a push plate 2 341 elastically disposed in the cooling channel 2 340, and the push plate 1 331 is fixedly connected to the dynamic drive shaft 210, the cooling channel 1 330 is located outside the cavity 110, the cooling channel 2 340 is located between the shielding cylinder 120 and the inner wall of the cavity 110, and a coolant is provided between the push plate 1 331 and the push plate 2 341. The size of the push plate 1 331 is adapted to the inner diameter of the cooling channel 1 330, and the size of the push plate 2 341 is adapted to the inner diameter of the cooling channel 2 340, so that the push plate 1 331 and the push plate 2 341 are kept sealed. The cooling channel 1 330 and the cooling channel 2 340 are connected to form a U-shaped channel; the side wall of the cooling channel 1 330 is also provided with a heat-conducting fin 350. The push plate 2 341 is elastically arranged in the cooling channel 2 340 through the spring 2 342. When the moving conductive rod 130 and the static conductive rod 140 are in contact, the coolant is located in the cooling channel 1 330. Specifically as follows: when the moving conductive rod 130 and the static conductive rod 140 are in contact, the push plate 1 331 moves in a direction away from the cooling channel 2 340, and the coolant is drawn from the cooling channel 2 340 back to the cooling channel 1 330 for cooling. The side wall of the cooling channel 1 330 is also provided with a heat-conducting fin 350, and the heat-conducting fin 350 exchanges the temperature of the coolant in the cooling channel 1 330 with the outside air, and dissipates the heat to the outside. When the moving conductive rod 130 and the static conductive rod 140 are disconnected, the coolant is located in the cooling channel 2 340. Specifically, when the movable conductive rod 130 and the static conductive rod 140 are disconnected, the push plate 1 331 moves toward the cooling channel 2 340 , squeezes the coolant into the cooling channel 2 340 , and contacts the shielding tube 120 for cooling.

[0053] Working principle: When the arc extinguishing chamber 100 works normally, the rotating shaft 250 is rotated, and the rotating shaft 250 drives the guide plate 260 to rotate. Since the guide groove 261 on the guide plate 260 is adapted to the driving disk, the guide groove 261 drives the driving disk to move in the guide groove 261. The guide groove 261 is an arc groove, so that the driving disk produces a vertical displacement. When the driving disk moves to the lowermost end of the guide groove 261, the driving disk drives the driving shaft 210 to slide to the bottom end of the waist-shaped hole 150, and then presses the moving conductive rod 130 downward, so that the moving conductive rod 130 contacts the static conductive rod 140. Then the spring 1 220 presses the fixed plate 271 upward, and the fixed plate 271 drives the sleeve 270 to move upward, and the sleeve 270 drives the driving shaft 210 to move upward, so that the driving shaft 210 is located at the top of the waist-shaped hole 150. During this process, the push plate 1 331 moves away from the cooling channel 2 340, and draws the coolant from the cooling channel 2 340 back into the cooling channel 1 330 for cooling. The push plate 2 341, under the action of the spring 2 342, also squeezes the coolant toward the cooling channel 1 330, so that the coolant moves into the cooling channel 1 330. The side wall of the cooling channel 1 330 is also provided with a heat conducting fin 350, which exchanges the temperature of the coolant in the cooling channel 1 330 with the outside air and dissipates the heat to the outside.

[0054] When a short circuit occurs in the arc extinguishing chamber 100, the moving conductive rod 130 moves upward and disconnects from the static conductive rod 140. When the bottom end of the waist-shaped hole 150 moves upward and contacts the drive shaft 210, a time difference is generated, so that the arc generated in the arc extinguishing chamber 100 disappears during this period of time. Then the bottom end of the waist-shaped hole 150 pushes the drive shaft 210 upward, and the drive shaft 210 drives the push plate 1 331 to move and squeeze the coolant into the cooling channel 2 340 to cool down the shielding cylinder 120 (the force of the drive shaft 210 driving the push plate 1 331 to move upward is greater than the elastic force of the spring 2 342). At this time, the spring 2 342 of the push plate 2 341 is in a compressed state, which avoids the leakage phenomenon caused by the coolant entering the cooling channel 2 340 when an arc is generated.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
