Description

Technical Field

[0001] The present invention relates to an integrated power distribution busbar device, belonging to the technical field of power distribution in data computer rooms. Background Art

[0002] In recent years, the construction of IDC (Internet Data Center) data computer rooms has developed rapidly and continues to develop in the direction of high density, small volume, and large capacity. The previous power distribution cabinet power supply mode has problems such as large floor area and small capacity. With the sharp increase in power consumption demand, the installation requirements for power equipment are getting higher and higher, and the requirements for the feasibility, reliability, and standardization of the connection operation of the power system are also higher. The existing data computer rooms adopt a track-type power distribution busbar system to replace a power supply and distribution form of a row head cabinet plus a cable tray, which can greatly improve the above problems. The power distribution busbar is installed on the top of the equipment to reduce the floor area of the computer room.

[0003] However, as shown in the track-type busbar system Figure 6 it is composed of a busbar trunking, a terminal box, and a plug-in box. The conductive parts on the terminal box are connected to the conductive copper bars in the busbar trunking to achieve electrical connection between phases. The plug-in box is arranged at the bottom of the busbar trunking at the power-taking position. A circuit breaker is installed in the plug-in box, and a plug conductive part is provided on the upper adapter. The plug conductive part on the top of the plug-in box at each power feeding point is connected to the conductive copper bar on the busbar trunking to achieve power taking. On the one hand, the power distribution busbar device all adopts a plug-in box, and the plug-in box is arranged at the lower part of the busbar trunking, and the space on the top of the equipment is also limited. Therefore, the box body will also occupy a certain space in the computer room. Moreover, the plug conductive part on the adapter of the plug-in box penetrates through the busbar trunking. To connect or disconnect the plug conductive part on the adapter on the top of the plug-in box to the copper bar of the busbar trunking, special tools are required, and the installation operation is inconvenient. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated power distribution busbar device with a simple and reasonable structure, quick and convenient installation operation, no occupation of the computer room space, and good versatility.

[0005] The technical solution of the present invention to achieve the above purpose is: an integrated power distribution busbar device, characterized in that it includes a busbar trunking body, a T-shaped conductive copper bar, a sliding bottom plate, and a tapping unit;

[0006] The busbar trunking body includes a top plate, side plates on both sides, and a bottom plate to form a three-sided closed structure with an open bottom; multiple copper bar channels are provided on the inner side of the side plates of the busbar trunking body, and L-shaped rib plates extending inward are provided at the lower parts of the two side plates to form a lower channel with the bottom plate;

[0007] The T-shaped conductive copper bar includes an integrated vertical plate and a horizontal plate horizontally arranged inside the vertical plate, and the vertical plate is insulated and installed in the corresponding copper bar channel of the side plate;

[0008] The described sliding bottom plate is used to install the tapping unit. Both sides of the sliding bottom plate are arranged in the lower channel and can be moved and fixed on the main body of the busbar trunking;

[0009] The described tapping unit is arranged in the main body of the busbar trunking and includes a circuit breaker, an insulating housing and a telescopic conductive mechanism. The circuit breaker and the insulating housing are installed on the sliding bottom plate. The wiring terminal of the circuit breaker and the circuit breaker handle are respectively arranged on the upper and lower sides of the sliding bottom plate; Limiting seats corresponding to the horizontal plates of each T-shaped conductive copper bar and provided with guiding holes are arranged on both sides of the insulating housing;

[0010] The described telescopic conductive mechanism includes an operating handle and conductive clamping plates corresponding to each T-shaped conductive copper bar. The operating handle installed on the insulating housing is connected to each conductive clamping plate and is used to synchronously drive each conductive clamping plate to telescopically move;

[0011] The conductive clamping plate is arranged through the guiding hole of the limiting seat and can move. The inner side of each conductive clamping plate is electrically connected to the corresponding power supply end of the circuit breaker and is used to lead electricity to the circuit breaker. A space for accommodating the T-shaped conductive copper bar is arranged between the two clamping heads on the outer side of the conductive clamping plate, and inclined clamping arms are arranged on the inner sides of the two clamping heads; When the conductive clamping plate retracts, the guiding hole tightens the distance between the two clamping arms, and the two clamping heads clamp the T-shaped conductive copper bar to take electricity; When the conductive clamping plate extends, the distance between the two clamping arms is enlarged, and the two clamping heads loosen the T-shaped conductive copper bar.

[0012] The distribution busbar trunking device of the present invention adopts a busbar trunking main body, T-shaped conductive copper bars, a sliding bottom plate and a tapping unit. The tapping unit is installed on the sliding bottom plate and can move and be fixed in the main body of the busbar trunking. Therefore, the sliding bottom plate and the circuit breaker tapping unit can be integrally hidden inside the cavity of the busbar trunking main body through ingenious design. Since the overall size of the distribution busbar device is greatly reduced, the space utilization rate of the computer room is greatly improved, and the production cost is reduced. At the same time, the number of circuit endpoints is reduced, making the overall electrical performance more reliable. The present invention cancels the plug-in box and realizes the integration of the busbar trunking and the plug-in box. The structure is simple and reasonable, and modular design can be realized. The present invention synchronously drives each conductive clamping seat to telescopically move through the operating handle. Without other special tools, the clamping heads on the conductive clamping seat can clamp or loosen the T-shaped conductive copper bar. The installation operation is quick and convenient, the installation cycle can be shortened, and the busbar installation efficiency can be greatly improved. The present invention controls the distance between the two clamping heads through the limiting seat. Therefore, it can be applied to T-shaped conductive copper bars with different thicknesses and has good versatility. Description of the Drawings

See Figure 1 and 2As shown in the figure, the busbar trunking body 1 of the present invention can be made of aluminum alloy into profiles, having reliable mechanical strength. On the top plate 1-1 of the busbar trunking body 1 of the present invention, upper T-shaped rib plates 1-2 are symmetrically provided and two upper channels are formed with the side plates 1-3 to form an upper installation channel of the busbar trunking body 1, on which a hoisting mechanism can be installed and can be moved and adjusted along the upper channel. Figure 1 、 2 As shown in the figure, the T-shaped conductive copper bar 2 of the present invention includes an integral vertical plate and a horizontal plate horizontally arranged inside the vertical plate. The vertical plate is insulated and installed in the corresponding copper bar channel 1-4 of the side plate 1-3, and the vertical plate is installed in the insulating sleeve 3, so that the T-shaped conductive copper bar 2 is used as a conductor to take power for the tapping units at each power feeding point.

[0023] See Figures 1 - 4 As shown in the figure, the sliding bottom plate 7 of the present invention is used to install the tapping unit. The two sides of the sliding bottom plate 7 are arranged in the lower channel 1-5 and can be moved and fixed on the busbar trunking body 1. Therefore, power can be taken at any tapping point of the busbar trunking body 1. The present invention can be provided with a corresponding plurality of threaded holes on the bottom plate 1-6 of the busbar trunking body 1. The fastener 9 is connected in the threaded hole, and the sliding bottom plate 7 is pressed against the L-shaped rib plate by the fastener 9 to fix the sliding bottom plate 7.

[0024] See Figures 1 - 4 As shown in the figure, the tapping unit of the present invention is arranged in the busbar trunking body 1, without a dedicated transfer box, so that the space occupied in the computer room can be reduced. The tapping unit of the present invention includes a circuit breaker 8, an insulating housing 5 and a telescopic conductive mechanism. The circuit breaker 8 and the insulating housing 5 are installed on the sliding bottom plate 7. The circuit breaker 8 adopts a miniature circuit breaker. For example, the circuit breaker 8 is a standard 9mm-width miniature circuit breaker. The wiring terminal 8-1 and the circuit breaker handle 8-2 of the circuit breaker 8 are respectively arranged on the upper and lower sides of the sliding bottom plate 7, so that it is convenient for the operator to operate. See Figure 3 、 4 As shown in the figure, the circuit breaker 8 of the present invention is obliquely installed on the sliding bottom plate 7, and the wiring terminal 8-1 of the circuit breaker 8 is located at the lower part of the sliding bottom plate 7. The insulating housing 5 is installed on the upper part of the sliding bottom plate 7 and covers the circuit breaker 8, and the circuit breaker handle 8-2 on the upper part of the circuit breaker 8 passes through the insulating housing 5. The present invention arranges the tapping unit in the busbar trunking body 1, which is convenient for operating the circuit breaker handle 8-2 to realize the opening and closing operation of the circuit breaker 8, and the wiring terminal 8-1 is not restricted by the operating space, which is convenient for wiring operation.

[0025] See Figure 5 As shown in the figure, on both sides of the insulating housing 5 of the present invention, there are provided limit seats 5-1 corresponding to the horizontal plates of the respective T-shaped conductive copper bars 2 and having guide holes; See Figure 1 、 2 As shown in the figure, three T-shaped conductive copper bars 2 can be adopted in the present invention, so the circuit breaker 8 and the tapping unit are three-phase three-wire.

[0026] See Figures 1 - 4 As shown, the telescopic conductive mechanism of the present invention includes an operating handle 6 and conductive clamping plates 4 corresponding to each T-shaped conductive copper bar 2. The operating handle 6 installed on the insulating housing 5 is connected to each conductive clamping plate 4 and is used to synchronously drive each conductive clamping plate 4 to telescopically move. Therefore, by operating the handle 6, each conductive clamping plate 4 can be controlled to telescopically move. When each conductive clamping plate 4 moves and clamps the corresponding T-shaped conductive copper bar 2, power can be taken, and when each conductive clamping plate 4 moves and releases the corresponding T-shaped conductive copper bar 2, power can be cut off, which is convenient for installation or removal and has good versatility.

[0027] See Figures 3 - 5 As shown, the conductive clamping plate 4 of the present invention is inserted into the guiding hole of the limiting seat 5-1 and can move. The inner side of each conductive clamping plate 4 is electrically connected to the corresponding power supply end of the circuit breaker 8 and is used to lead electricity to the circuit breaker 8. Each conductive clamping plate 4 can be electrically connected to each phase power supply end corresponding to the circuit breaker 8 by using flexible wires, and each phase wiring terminal 8-1 corresponding to the circuit breaker 8 is electrically connected to an external device to provide power to the external device. See Figure 5 As shown, there is a space for accommodating the T-shaped conductive copper bar 2 between the two clamping heads 4-1 on the outer side of the conductive clamping plate 4 of the present invention, and inclined clamping arms 4-2 are provided on the inner sides of the two clamping heads 4-1. The included angle α between the clamping head 4-1 and the clamping arm 4-2 is between 125° and 145°, such as the included angle α between the clamping head 4-1 and the clamping arm 4-2 is 135°. When the conductive clamping plate 4 retracts, the guiding hole tightens the distance between the two clamping arms 4-2, and the two clamping heads 4-1 clamp the T-shaped conductive copper bar 2 to take power; when the conductive clamping plate 4 extends, the distance between the two clamping arms 4-2 is enlarged, and the two clamping heads 4-1 release the T-shaped conductive copper bar 2. Therefore, the operating handle 6 can be used to simultaneously make each conductive clamping plate 4 act simultaneously, and then connect or release the T-shaped conductive copper bar to take power. The present invention can conveniently adjust the clamping force of the two clamping heads by the moving distance of the conductive clamping plate 4, reliably connect with the T-shaped conductive copper bar, and can be used on T-shaped conductive copper bars 2 with different thicknesses. In order to improve the strength and clamping force of the conductive clamping plate 4 of the present invention, the clamping head 4-1 on the conductive clamping plate 4 has an inward turned edge 4-11, and the inward turned edge 4-11 faces the T-shaped conductive copper bar 2.

[0028] See Figure 3 、 4 As shown, two limiting seats 5-1 are spaced at intervals corresponding to each T-shaped conductive copper bar 2 on the insulating housing 5 of the present invention. Two conductive clamping plates 4 are installed in the corresponding limiting seats 5-1. The inner sides of the two conductive clamping plates 4 are connected to an intermediate connector, and the intermediate connector is electrically connected to the corresponding power supply end of the circuit breaker 8. Since two conductive clamping plates 4 take power corresponding to one T-shaped conductive copper bar 2, the reliability of power taking can be improved.

[0029] See Figure 5As shown, the limit seat 5-1 of the present invention includes a guide seat 5-11 and an integral base 5-12. A guide hole is provided in the guide seat 5-11. The guide hole is a rectangular hole and can be set according to the cross-sectional shape of the conductive clamping plate 4. The limit seat 5-1 and the insulating housing 5 are of an integral structure or can also be a split structure. There are orifices larger than the guide hole on both sides of the insulating housing 5. The limit seat 5-1 is arranged at the orifice of the insulating housing 5 and the base 5-12 is detachably installed on the insulating housing 5, so it can be adjusted according to the positions of the T-shaped conductive copper bars 2 on the busbar trunk 1.

[0030] See Figure 3 、 4 As shown, the present invention has a handle support seat 5-2 on the insulating housing 5. The operating handle 6 is installed on the handle support seat 5-2 and can rotate relative to the handle support seat 5-2. An arc-shaped groove for guiding the operating handle 6 is provided on the handle support seat 5-2. The handle support seat 5-2 of the present invention is provided with positioning holes for positioning the operating handle 6 at both ends of the arc-shaped groove. The positioning holes correspond to the positions where the conductive clamping plate 4 clamps the T-shaped conductive copper bar 2 or the positions where the conductive clamping plate 4 releases the T-shaped conductive copper bar 2. An elastic member is provided on the operating handle 6. The elastic member is arranged in the positioning hole on the handle support seat 5-2 to limit the operating handle 6. A blind hole can be provided on the operating handle 6. The elastic member can adopt a spring and a ball. The spring and the ball are arranged in the blind hole on the operating handle 6. The positioning hole is a hemispherical hole. Rotate the operating handle 6 to make the ball arranged in the corresponding positioning hole to limit the operating handle 6. Each soft connecting member connected to the operating handle 6 is connected to the corresponding conductive clamping plate 4. The operating handle 6 is provided with an arc-shaped groove for limiting each soft connecting member in the circumferential direction. One end of each soft connecting member is fixed on the operating handle 6 and corresponds to each arc-shaped groove. When the operating handle 6 rotates, it drives the corresponding soft connecting member to retract or extend along the arc-shaped groove, and then drives the corresponding conductive clamping plate 4 to clamp the T-shaped conductive copper bar 2 or release the T-shaped conductive copper bar 2. The soft connecting member can adopt a soft wire, a spring or other rope locks, etc. The soft connecting member on the operating handle 6 of the present invention can also be an intermediate connecting member. One end of the intermediate connecting member is connected to the operating handle 6 and the other end is connected to the two conductive clamping plates 4.

[0031] See Figure 3 、 4As shown, the insulating housing 5 of the present invention is provided with a handle support seat 5-2. The operating handle 6 is mounted on the handle support seat 5-2 and can rotate and move back and forth relative to the handle support seat 5-2. The handle support seat 5-2 is provided with a spiral groove for guiding the operating handle 6, and positioning holes are provided at both ends of the spiral groove. The operating handle 6 is provided with corresponding elastic members, and the elastic members are arranged in the positioning holes on the handle support seat 5-2 to limit the operating handle 6. Similarly, an elastic member formed by a spring and a ball is provided in the blind hole on the operating handle 6, and the positioning holes at both ends of the spiral groove are hemispherical holes. Rotating the operating handle 6 makes the ball arranged in the corresponding positioning hole to limit the operating handle 6. Each soft connecting member connected to the operating handle 6 is connected to the corresponding conductive clamping plate 4. The operating handle 6 is provided with spiral grooves for limiting each soft connecting member in the circumferential direction. One end of each soft connecting member is fixed on the operating handle 6 and corresponds to each spiral groove. The rotation direction of the spiral groove is opposite to that of the spiral groove. When the operating handle 6 rotates and moves, it drives the corresponding soft connecting member to retract or extend along the spiral groove, keeping each conductive clamping plate 4 moving, and then driving the corresponding conductive clamping plate 4 to clamp or loosen the T-shaped conductive copper row 2.

[0032] See Figure 3 , 4 As shown, the insulating housing 5 of the present invention is provided with a handle support seat 5-2. The operating handle 6 is mounted on the handle support seat 5-2 and can move back and forth relative to the handle support seat 5-2. The handle support seat 5-2 is provided with a straight groove for guiding the operating handle 6, and positioning holes are provided at the front end and the rear end of the straight groove. The operating handle 6 is provided with corresponding elastic members, and the elastic members are arranged in the positioning holes on the handle support seat 5-2 to limit the operating handle 6. Similarly, an elastic member formed by a spring and a ball is provided in the blind hole on the operating handle 6, and the positioning holes at both ends of the straight groove are hemispherical holes. Pushing and pulling the operating handle 6 makes the ball arranged in the corresponding positioning hole to limit the operating handle 6. In addition, the operating handle 6 is also provided with a straight groove with an inclined bottom surface. The cross-section of the operating handle is rectangular, and straight grooves corresponding to each conductive clamping plate 4 are provided on both sides of the operating handle. The inner side parts of each conductive clamping plate 4 abut against the corresponding straight grooves and are connected to the operating handle 6. When the operating handle 6 moves back and forth, the inclined bottom surface of the straight groove makes each conductive clamping plate 4 move, and then the conductive clamping plate 4 clamps or loosens the T-shaped conductive copper row 2.

[0033] In the present invention, at the position where the handle support seat 5-2 corresponds to the conductive clamping plate 4 clamping the T-shaped conductive copper row 2, more than two positioning holes can be provided, which can facilitate the adjustment of the clamping force and adapt to different thicknesses of the copper row.
