A complete set of high-voltage switchgear

Abstract

The present invention discloses a high-voltage switch complete set, which comprises a numerical control table, a cabinet door, and a high-voltage switch cabinet. The numerical control table is installed at the front end of the high-voltage switch cabinet, and the high-voltage switch cabinet is installed at the rear end of the cabinet door. When the electric wire plug is short-circuited and manually pulled out, the electric wire plug squeezes the deformed wire, so that the deformed wire is deformed and bent to fit the inner wall of the outer frame. Therefore, the pulling out of the electric wire plug can drive the outrigger to slide outward along the clamping block, and then the aluminum outer frame of the heat dissipation block can quickly dissipate the heat on the outrigger. The inertial force generated by the outrigger being pulled out can cause the swing block to swing upward along the inner frame, and the thrust generated by the rebound bar on the swing block can cause the swing block to swing downward along the inner frame and reset, so that the generated vibration can shake off the melted layer of the wire insulation at the bottom of the swing block.

Description

Technical Field

[0001] The present invention relates to the field of high-voltage switches, and in particular to a high-voltage switch complete set. Background Art

[0002] The KYN28-12 high-voltage switchgear cabinet is primarily used to receive and distribute electrical energy and participate in circuit control, protection, and monitoring. The KYN28-12 high-voltage switchgear cabinet is suitable for three-phase AC 50Hz power systems. By inserting the wire plug into the interface end of the KYN28-12 high-voltage switchgear cabinet, the control switch inside the KYN28-12 high-voltage switchgear cabinet can control, protect, and monitor the circuit. The wiring terminals of the KYN28-12 high-voltage switchgear cabinet are all independently routed, so that if a wire is broken, the wire can be directly unplugged and replaced without affecting the operation of other circuits. However, in the existing technology, if the wire plug inserted into the wiring terminal of the KYN28-12 high-voltage switchgear cabinet short-circuits, the internal temperature of the wiring terminal of the KYN28-12 high-voltage switchgear cabinet will rise rapidly. If the wiring terminal is not damaged and the wire is unplugged and a new wire is inserted in a short time, the high temperature inside the wiring terminal will affect the current transmission stability of the new wire. Summary of the Invention

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a high-voltage switch complete set of equipment, whose structure includes a numerical control table, a cabinet door, and a high-voltage switch cabinet, the numerical control table is installed at the front end position of the high-voltage switch cabinet, and the high-voltage switch cabinet is installed at the rear end position of the cabinet door; the high-voltage switch cabinet includes an outer frame, a wiring mechanism, a support frame, and a control switch, the wiring mechanism is fixed to the internal position of the support frame, the support frame is installed to the internal position of the outer frame, and the control switch is fixed to the internal upper end position of the support frame.

[0005] As a further improvement of the present invention, the wiring mechanism includes a cross bar, a track, and a wiring board. The track and the cross bar are an integrated structure. The rear end of the wiring board is movably engaged with the inner wall of the track. There are three wiring boards, which are evenly distributed in parallel at the front ends of the two cross bars.

[0006] As a further improvement of the present invention, the terminal board includes an outrigger, a terminal, a board surface, and a clamping block. The outrigger is movably engaged with the internal part of the terminal, the terminal is embedded in the internal position of the board surface, the front end of the clamping block is connected to the rear end of the board surface, and three outriggers are provided, which are evenly distributed in parallel inside the board surface.

[0007] As a further improvement of the present invention, the outrigger includes a contact reducing groove, a breathable cavity, a deformation wire, and an outer frame. The contact reducing groove is embedded in the internal position of the outer frame, the breathable cavity runs through the internal position of the outer frame, and the deformation wire is installed on the inner side of the contact reducing groove. The deformation wire adopts a filamentary structure made of spring steel with strong elasticity.

[0008] As a further improvement of the present invention, the air-permeable cavity includes a rebound bar, a swing block, and an inner frame. The rebound bar is installed between the upper end of the swing block and the inner wall of the inner frame. The swing block is hinged to the right side of the inner wall of the inner frame.

The base plate is installed between the inner wall of the sliding plate and the elastic bar. The elastic bar is movably engaged with the upper surface of the sliding plate. The throwing force generated by the swinging and resetting of the mechanism can cause the elastic bar to slide and extend to the lower left along the sliding plate.

[0011] The present invention has the following beneficial effects:

[0012] 1. When the wire plug is short-circuited and manually pulled out, the deformation wire can be deformed and bent to fit the inner wall of the outer frame through the extrusion of the wire plug, so that the deformation wire can fill the gap between the inner wall of the air permeable cavity and the wire plug. Therefore, pulling out the wire plug can drive the outrigger to slide outward along the card block, and then the aluminum outer frame of the heat sink can quickly dissipate the heat on the outrigger, so that when a new wire plug is inserted into the terminal, the internal temperature will not be too high.

[0013] 2. The inertial force generated by the outrigger being pulled out can cause the swing block to swing upward along the inner frame, and the thrust generated by the rebound bar on the swing block can cause the swing block to swing downward along the inner frame and reset quickly, so that the vibration generated can shake off the melted layer of wire insulation at the bottom of the swing block, effectively avoiding the situation where the wire plug is made of a simple wire connecting conductive sheet, which will cause the wire insulation to melt due to heat and adhere to the inner wall of the outrigger near the front end and be difficult to remove.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 5 As shown:

[0026] The present invention provides a high-voltage switchgear complete set, which comprises a numerical control table 1, a cabinet door 2, and a high-voltage switchgear 3. The numerical control table 1 is mounted at the front end of the high-voltage switchgear 3, and the high-voltage switchgear 3 is mounted at the rear end of the cabinet door 2. The high-voltage switchgear 3 comprises an outer frame 31, a wiring mechanism 32, a support frame 33, and a control switch 34. The wiring mechanism 32 is fixed to an inner position of the support frame 33, the support frame 33 is mounted to an inner position of the outer frame 31, and the control switch 34 is fixed to an inner upper end of the support frame 33.

[0027] Among them, the wiring mechanism 32 includes a cross bar a1, a track a2, and a terminal block a3. The track a2 and the cross bar a1 are an integrated structure. The rear end of the terminal block a3 is movably engaged with the inner wall of the track a2. There are three terminal blocks a3, which are evenly distributed in parallel at the front ends of the two cross bars a1. The terminal blocks a3 can be freely translated on the cross bar a1, thereby avoiding the situation where the wires cannot reach the terminal blocks a3 due to insufficient length.

[0028] Among them, the terminal board a3 includes an outrigger a31, a terminal a32, a board surface a33, and a clamping block a34. The outrigger a31 is movably engaged with the internal part of the terminal a32. The terminal a32 is embedded in the internal position of the board surface a33. The front end of the clamping block a34 is connected to the rear end of the board surface a33. The outrigger a31 is provided with three, and is evenly distributed in parallel inside the board surface a33. When the wire plug is inserted into the interior of the terminal a32, the outrigger a31 can be pushed into the interior of the terminal a32.

[0029] Among them, the outrigger a31 includes a contact reducing groove b1, a breathable cavity b2, a deformable wire b3, and an outer frame b4. The contact reducing groove b1 is embedded in the internal position of the outer frame b4, the breathable cavity b2 runs through the internal position of the outer frame b4, and the deformable wire b3 is installed on the inner side of the contact reducing groove b1. The deformable wire b3 adopts a filamentary structure made of spring steel with strong elasticity. The thrust generated by the wire plug can make the deformable wire b3 deform and bend to fit the inner wall of the outer frame b4, so that the deformable wire b3 can fill the gap between the inner wall of the outer frame b4 and the wire plug, so that the outer frame b4 can be pulled outward along with the wire plug.

[0030] Detailed usage and effects of this embodiment:

[0031] In the present invention, by inserting the wire plug into the wiring mechanism 32 inside the high-voltage switch cabinet 3, the wire plug can squeeze the outrigger a31 on the terminal block a3 into the interior of the terminal a32 when it is inserted, so that the wire plug can normally contact the inner side of the terminal a32 for connection, and the clamping block a34 on the terminal block a3 is clamped into the track a2 and can be translated along the crossbar a1, thereby avoiding the situation where the wire needs to be replaced because it is short-circuited and cannot reach the terminal a32. When the wire plug is manually pulled out due to a short circuit, the deformation wire b3 can be squeezed by the wire plug to make the deformation wire b3 The wire b3 is deformed and bent to fit the inner wall of the outer frame b4, so that the deformed wire b3 can fill the gap between the inner wall of the air cavity b2 and the wire plug. Therefore, when the wire plug is pulled out, it can drive the outrigger a31 to slide outward along the block a34, and then the aluminum outer frame b4 of the heat dissipation block can quickly dissipate the heat on the outrigger a31, and the air cavity b2 can enhance the contact area between the outer frame b4 and the outside world, thereby further accelerating the heat dissipation speed of the outrigger a31, so that when the new wire plug is inserted into the terminal a32, the temperature inside c32 will not be too high.

[0032] Example 2

[0033] like Figure 6-Figure 8 As shown:

[0034] Among them, the air permeable cavity b2 includes a rebound bar b21, a swing block b22, and an inner frame b23. The rebound bar b21 is installed between the upper end of the swing block b22 and the inner wall of the inner frame b23. The swing block b22 is hinged to the right side of the inner wall of the inner frame b23. The inertial force generated by the mechanism being pulled outward can make the swing block b22 swing upward along the inner frame b23, and then the rebound bar b21 pushes the swing block b22 to reset, which can generate vibration to shake off the melted layer of the wire insulation at the bottom of the swing block b22.

[0035] Among them, the swing block b22 includes a receiving plate c1, a weight-increasing block c2, a separation groove c3, and an extension mechanism c4. The weight-increasing block c2 is fixed to the internal position of the receiving plate c1, and the separation groove c3 and the receiving plate c1 are an integrated structure. The right side of the extension mechanism c4 is connected to the left side of the receiving plate c1. The separation groove c3 is a concave structure, and the separation groove c3 can reduce the contact area between the melted layer of the wire insulation and the bottom of the receiving plate c1.

[0036] Among them, the extension mechanism c4 includes a sliding plate c41, a base plate c42, and an elastic bar c43. The base plate c42 is installed between the inner wall of the sliding plate c41 and the elastic bar c43. The elastic bar c43 is movably engaged with the upper surface of the sliding plate c41. The throwing force generated by the swinging and resetting of the mechanism can cause the elastic bar c43 to slide and extend to the lower left along the sliding plate c41, so that the elastic bar c43 pushes off the melted layer of the residual wire insulation at the bottom of the object.

[0037] Detailed usage and effects of this embodiment:

[0038] In the present invention, if the wire plug is made of a simple wire connecting conductive sheet, the insulation of the wire will fit into the inner wall of the outrigger a31. If such a wire plug is short-circuited, the insulation of the wire will melt due to heat and adhere to the inner wall of the outrigger a31 near the front end, which is difficult to remove. The inertial force generated by the outrigger a31 being pulled outward can cause the swing block b22 to swing upward along the inner frame b23, and then the thrust generated by the rebound bar b21 on the swing block b22 can cause the swing block b22 to swing downward quickly along the inner frame b23 to reset, so that the vibration generated can shake off the melted layer of the wire insulation at the bottom of the swing block b22, and the separation groove c3 can reduce the bearing capacity. The contact area between the connecting plate c1 and the melted layer of the wire insulation can be increased by adding weight to the connecting plate c1 through the weight-adding block c2, thereby accelerating the downward swing speed of the swing block b22, so that the melted layer of the wire insulation at the bottom of the swing block b22 can be shaken off more easily, and the inertial force generated by the downward swinging reset of the swing block b22 can make the elastic bar c43 slide out along the lower left side of the sliding plate c41, so that the elastic bar c43 pushes down the residual melted layer of the wire insulation at the bottom of the inner frame b23, effectively avoiding the situation where the wire plug is made of a simple wire connecting conductive sheet, which will cause the wire insulation to melt due to heat and adhere to the inner wall of the outrigger a31 near the front end and be difficult to remove.
