Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to an insulation protection device for an integrated distribution box. Background Art

[0002] The integrated distribution box is a new type of integrated control box that integrates power distribution, metering, protection, control and reactive power compensation. The integrated distribution box is widely used in substations, factories, industrial and mining enterprises, large power plants, petroleum, chemical enterprises, large steel mills, high-rise building power centers, reactive power compensation, metering and power distribution.

[0003] The integrated distribution box insulation protection device in the prior art will have the following disadvantages when in use: due to the interaction between the foam pad and the W-shaped switch card, the rubber ring has relative elasticity, and the rubber ring fixed on the box door can form a three-dimensional basin-shaped structure block. When the box door is closed, the box body has a good insulation effect. When the box door is closed toward the box body, the foam pad will be stressed first, and the foam pad will be aligned with the raised position in the middle of the switch card at this time, and will borrow force from the inner side of the W-shaped switch card, and will swing left and right and slide down, resulting in gradual concentration of filling inside the W-shaped switch card. The lateral stretching reduces the thickness of the rubber ring on the box door, reduces the thickness of the rubber ring on the box door, and reduces the tensile strength and flexibility of the W-shaped switch card in the rubber ring, making it difficult to achieve the purpose of using the rubber ring as a partition between the box door and the box body.

[0004] Therefore, there is an urgent need for an integrated distribution box insulation protection device to solve the above problems. Summary of the invention

[0005] The present invention provides an insulation protection device for an integrated distribution box, which can improve the pressure bearing capacity of an insulating rubber ring and ensure the insulation protection effect of the integrated distribution box.

[0006] To achieve this purpose, the present invention adopts the following scheme:

[0007] The invention discloses an insulation protection device for an integrated distribution box, which is used for an integrated distribution box. The integrated distribution box comprises a box body, a box door and an insulation protection device for the integrated distribution box. The box door is hinged to the box body. The insulation protection device for the integrated distribution box is arranged on the box door. The insulation protection device for the integrated distribution box comprises an insulating rubber ring, which is arranged on the side of the box door facing the box body. The insulating rubber ring comprises a switch card, a force plate, a foam pad, a booster and a colloid. One end of the colloid is connected to the box door, and the other end of the colloid is connected to the force plate. The colloid, the force plate and the box door form a accommodating space. The switch card is movably arranged in the accommodating space. The cross-section of the switch card is W-shaped. One side of the switch card abuts the force plate, and the other side abuts the box door to insulate the box door from the box body. The foam pad is filled between the switch card and the force plate. The cross-section of the booster is arched. The booster is arranged on the side of the switch card close to the box door. The booster can provide support for the switch card.

[0008] As an optional solution, the power-assisting body includes a locking assembly, a swing arm, a pushing piece, a contact angle and a protective pocket. The locking assembly is arranged between the swing arm and the switch card through the protective pocket. One end of the swing arm is connected to the pushing piece, and the other end of the swing arm is connected to the contact angle. The contact angle is arranged between the switch card and the foam pad.

[0009] As an alternative, an interference angle clearance fit is provided between the switch card and the foam pad.

[0010] As an optional solution, the jamming assembly includes a fitting strip, a buffer plate, a card bag and a sealing piece. The fitting strip is connected to the buffer plate, the sealing piece is arranged at both ends of the fitting strip and the buffer plate, and a connecting groove is opened in the middle of the fitting strip.

[0011] As an optional solution, the blocking member includes a pedal, a folding pad, a handrail and a running-in layer, the folding pad, the running-in layer and the handrail are stacked, and the pedal is arranged on one side of the handrail and the running-in layer.

[0012] As an optional solution, the pushing member includes a deflection plate, a support rod, a spacer, a linkage member and a divergence cover. The deflection plate is connected to the divergence cover through a linkage member. The deflection plate is movably engaged on the swing arm. A spacer is movably provided on the divergence cover through the support rod, and the spacer is provided on the foam pad.

[0013] As an alternative, the spacer is provided on the foam pad with a clearance fit.

[0014] As an optional solution, the linkage parts include an inner kneading clamp, a flip plate, side wings, interlocking teeth and a bearing seat. The inner kneading clamp is connected to the flip plate and side wings, the inner kneading plate is connected to the interlocking teeth, and the side wings are movably engaged with the divergence cover through the bearing seat.

[0015] As an option, the copy board has a fan-shaped structure.

[0016] As an option, the copy plate is made of a resilient material.

[0017] The beneficial effects of the present invention are:

[0018] In the integrated distribution box insulation protection device provided by the present invention, when the box door is closed, that is, when insulation protection is required, the box door squeezes the force plate to move closer to the box body. At this time, the switch card with a W-shaped cross-section is deformed by force, and the arched booster body is set in the switch card. The booster body provides support for the switch card, which can prevent the switch card from being pulled in the accommodation space and reduce the support height, so as to ensure the load-bearing capacity of the switch card in the accommodation space. At the same time, the switch card cooperates with the foam pad to increase the support capacity of the colloid, avoid excessive changes in the overall thickness of the insulating rubber ring, and thus maintain a good insulation protection capability.

[0038] Embodiment 1

[0039] like Figure 1 and Figure 2 As shown, an insulation protection device for an integrated distribution box is used for an integrated distribution box, the integrated distribution box comprises a box body 2, a box door 3 and an insulation protection device for the integrated distribution box, the box door 3 is hinged to the box body 2, and the insulation protection device for the integrated distribution box is arranged on the box door 3. The integrated distribution box also comprises components 4 and heat dissipation ports 5, the components 4 and the heat dissipation ports 5 are electrically connected, and the components 4 and the heat dissipation ports 5 are arranged on the box body 2.

[0040] The insulation protection device of the integrated distribution box includes an insulating rubber ring 1, which is arranged on the side of the box door 3 facing the box body 2. The insulating rubber ring 1 includes a switch card 11, a force plate 12, a foam pad 13, a booster 14 and a colloid 15. One end of the colloid 15 is connected to the box door 3, and the other end of the colloid 15 is connected to the force plate 12. The colloid 15, the force plate 12 and the box door 3 form a receiving space 16. The switch card 11 is movably arranged in the receiving space 16. The cross-section of the switch card 11 is W-shaped. One side of the switch card 11 abuts the force plate 12, and the other side abuts the box door 3 to insulate the box door 3 from the box body 2. The foam pad 13 is filled between the switch card 11 and the force plate 12. The cross-section of the booster 14 is arched. The booster 14 is arranged on the side of the switch card 11 close to the box door 3. The booster 14 can provide support for the switch card 11. Through the above arrangement, when the box door 3 is closed, that is, when insulation protection is required, the box door 3 presses the force plate 12 to move closer to the box body 2. At this time, the switch card 11 with a W-shaped cross section is deformed by force, and the arched booster body 14 is arranged in the switch card 11. The booster body 14 provides support for the switch card 11, which can prevent the switch card 11 from being pulled in the accommodating space 16 and reducing the support height, so as to ensure the load-bearing capacity of the switch card 11 in the accommodating space 16. At the same time, the switch card 11 cooperates with the foam pad 13 to increase the support capacity of the colloid 15, avoid excessive changes in the overall thickness of the insulating rubber ring 1, and thus maintain a good insulation protection capability.

[0041] Please refer to Figure 3 Specifically, the power-assisting body 14 in this embodiment includes a locking assembly 141, a swing arm 142, a pushing piece 143, a contact angle 144 and a protective pocket 145. The locking assembly 141 is arranged between the swing arm 142 and the switch card 11 through the protective pocket 145. One end of the swing arm 142 is connected to the pushing piece 143, and the other end of the swing arm 142 is connected to the contact angle 144. The contact angle 144 is arranged between the switch card 11 and the foam pad 13.

[0042] Preferably, the contact angle 144 is provided between the switch card 11 and the foam pad 13 with clearance fit. When the booster 14 provides support for the switch card 11, the blocking component 141 and the push piece 143 cooperate on the swing arm 142. When the foam pad 13 and the inner side of the switch card 11 leverage each other and swing down left and right, they will first press on the force-bearing side of the push piece 143, driving the push piece 143 to slide and press along the swing arm 142, so that the blocking component 141 arches upward, and stops tilting with the help of the contact angle 144, and wraps around the middle of the switch card 11, so as to ensure the support effect of the switch card 11.

[0043] Embodiment 2

[0044] The basic structure of the insulation protection device for the integrated distribution box provided in this embodiment is the same as that in the first embodiment, and only some structures are different. This embodiment only describes the structures that are different from the insulation protection device for the integrated distribution box provided in the first embodiment.

[0045] Please refer to Figure 4 The blocking component 141 in this embodiment includes a sleeve strip 1411, a buffer plate 1412, a card bag 1413 and a blocking piece 1414. The sleeve strip 1411 is connected to the buffer plate 1412. The blocking piece 1414 is arranged at both ends of the sleeve strip 1411 and the buffer plate 1412. A connecting groove 1415 is provided in the middle of the sleeve strip 1411. When the blocking component 141 is arched to provide support, the buffer plate 1412 can provide a buffering effect. With the help of the blocking piece 1414, the card bag 1413 can be slidably arranged inside the protective pocket 145, driving the swing arm 142 of the protective pocket 145 to swing outward and receive the deflection of the foam pad 13, thereby playing the role of correcting and stopping.

[0046] Please refer to Figure 5 Specifically, the blocking member 1414 in this embodiment includes a pedal 14141, a folding pad 14142, a handrail 14143 and a running-in layer 14144. The folding pad 14142, the running-in layer 14144 and the handrail 14143 are stacked, and the pedal 14141 is arranged on one side of the handrail 14143 and the running-in layer 14144.

[0047] Please refer to Figure 6 The pushing member 143 in this embodiment includes a deflection plate 1431, a support rod 1432, a spacer 1433, a linkage member 1434 and a divergence cover 1435. The deflection plate 1431 is connected to the divergence cover 1435 through the linkage member 1434. The deflection plate 1431 is movably engaged with the swing arm 142. The divergence cover 1435 is movably provided with a spacer 1433 through the support rod 1432. The spacer 1433 is provided on the foam pad 13.

[0048] Preferably, the spacer 1433 in this embodiment is arranged on the foam pad 13 with a clearance fit.

[0049] Please refer to Figure 7 The linkage member 1434 in this embodiment includes an inner kneading clamp 14341, a flip plate 14342, side wings, interlocking teeth 14343 and a bearing seat 14344. The inner kneading clamp 14341 is connected with the flip plate 14342 and the side wings, the inner kneading plate is connected with the interlocking teeth 14343, and the side wings are movably engaged with the divergence cover 1435 through the bearing seat 14344. Preferably, the flip plate 14342 is a fan-shaped structure.

[0050] Further preferably, the flip plate 14342 in this embodiment is made of elastic material. Specifically, the flip plate 14342 can be made of rubber material to ensure that the flip plate 14342 has elasticity and flexibility, and can cooperate with the support rod 1432 to provide a connection area for the spacer 1433 to produce a supporting effect.

[0051] During use of the insulation protection device for the integrated distribution box provided in this embodiment, the foam pad 13 is tilted and pressed on the spacer 1433, which will push the spacer 1433 along the side of the flip, and with the help of the divergent cover 1435, a large area of ​​force is applied to the side wing on the same side. The side wing is on the bearing seat 14344, pushing the inner kneading clamp 14341 to cross through the interlocking teeth 14343 to stabilize the deflection of the switch card 11. Among them, the side wing provides a fulcrum for the divergent cover 1435 to extend sideways, so that the spacer 1433 on the divergent cover 1435 can slide down to one end of the sliding arm, and at the same time press the offset plate to synchronously cut sideways, pushing the swing arm 142 to swing downward, changing the pressure of the protective pocket 145 on the card capsule 1413, so that the card capsule 1413 is pressed and hardened to provide support. By pressing the two sides of the buffer plate 1412 and the running-in layer 14144 with the handle 14143, the running-in layer 14144 and the tip of the fitting strip 1411 slide against each other, so that the pedal 14141 can be bent into a full bow state. The folding pad 14142 bends downward, and the buffer plate 1412 is strengthened to swing in the middle of the switch hole on the fitting strip 1411, further pushing the card bag 1413 in the opposite direction to be close to each other and tighten. The swing arm 142 is expanded, so that the card bag 1413 has enough power to move toward the other end of the hollow structure of the swing arm 142 through the protective bag 145, and finally support it on the inclined high depression of the deflection plate 1431, so that the swing arm 142 has two support points in opposite directions, and stably hooks back and swings down along the inner side of the switch card 11, and slides with the help of the contact angle 144 to stop on both sides of the middle of the switch card 11, which can serve as a space for the foam pad 13 to swing, ensuring the bearing pressure of the switch card 11 and the three-dimensional effect of the colloid 15, ensuring the tensile strength and flexibility of the switch card 11 in the rubber ring, and enhancing the insulation protection effect of the equipment.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods thereof. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
