Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and particularly to a power distribution device. Background Art

[0002] At present, a power distribution device is provided in a power distribution cabinet to distribute power to each electrical device. Among them, the traditional power distribution device includes a disconnector, a busbar, and a circuit breaker. The disconnector and the busbar, and the disconnector and each circuit breaker are connected by wires. In order to improve the working continuity of the power distribution device and prevent the need to disconnect the disconnector for maintenance when any circuit breaker fails, in some power distribution devices, multiple connection ends of the circuit breaker are correspondingly inserted into multiple phase bars of the busbar to achieve a quick-disconnectable connection similar to hot plugging. Specifically, a clamping portion is provided at the connection end of the circuit breaker, and the clamping portion clamps the upper and lower surfaces of the phase bar to achieve this connection. Due to the C-shaped structure of the clamping portion, the distance between the clamping portion of any connection end and the clamping portion of the adjacent connection end, and the distance between the clamping portion of any connection end and the adjacent phase bar are relatively short, resulting in a relatively high probability of safety accidents such as short circuits and electric leakage. Summary of the Invention

[0037] As Figures 1 to 10 shown, a power distribution device of the present invention includes: a busbar device 1 and a circuit breaker assembly 2, including a plurality of insulating assemblies 11 arranged in sequence from top to bottom. The insulating assemblies 11 extend along a first direction. The insulating assembly 11 includes an insulating row 111 and a phase row 112. A first accommodating cavity 1111 is provided in the insulating row 111. A first opening 1112 penetrating through the first accommodating cavity 1111 is provided on the side of the insulating row 111 relative to a second direction. The circuit breaker assembly 2 is disposed on one side of the busbar device 1 along the second direction corresponding to the first opening 1112. The circuit breaker assembly 2 includes a circuit breaker body 21 and a plurality of connecting assemblies 22. A plurality of connection ends are provided on the circuit breaker body 21. The connection ends, the connecting assemblies 22, and the insulating assemblies 11 correspond to each other one by one. The connecting assembly 22 includes a connecting member 221 and an insulating sleeve 222. The insulating sleeve 222 is sleeved on the outer side of the connecting member 221. Two ends of the connecting member 221 are respectively set as a first end 2211 and a second end 2212. The first end 2211 is connected to the connection end. The second end 2212 passes through the first opening 1112 and extends into the first accommodating cavity 1111 and is connected to the phase row 112.

[0038] In the above technical solution, a plurality of insulating components 11 of the busbar device 1 are arranged in sequence from top to bottom. The phase bar 112 is arranged in the first accommodation cavity 1111 of the insulating bar 111, and the insulating bar 111 surrounds the phase bar 112, so that the phase bar 112 has good insulation to prevent accidents such as short circuits and electric leakage due to too small a distance between the connecting pieces 221. Further, the circuit breaker assembly 2 is arranged on one side of the busbar device 1 corresponding to the first opening 1112 to facilitate the circuit breaker assembly 2 to pass through the first opening 1112 and connect to the phase bar 112. Further, in the connecting assembly 22 of the circuit breaker assembly 2, the first end 2211 of the connecting piece 221 is connected to the connecting end of the circuit breaker body 21, and the second end 2212 of the connecting piece 221 passes through the first inlet and extends into the first accommodation cavity 1111 to connect to the phase bar 112, so that the circuit breaker assembly 2 can be inserted into the first accommodation cavity 1111 along the second direction for connection. Further, the insulating sleeve 222 is sleeved on the outer side wall of the connecting piece 221, so that the connecting piece 221 has good insulation to prevent accidents such as short circuits and electric leakage due to too small a distance between the connecting pieces 221; In summary, the insulation between the phase bars 112, between the connecting pieces 221, and between the phase bar 112 and the adjacent connecting pieces 221 of the power distribution device of the present invention is good, and the probability of safety accidents such as short circuits and electric leakage is low.

[0039] Further, the insulating component 11 further includes an insulating curtain 113. The insulating curtain 113 is arranged at the first opening 1112 to close the first opening 1112. The insulating curtain 113 is connected to the insulating bar 111. The insulating curtain 113 has elasticity. When the second end 2212 passes through the first opening 1112, the insulating curtain 113 is pushed into the first accommodation cavity 1111 by the second end 2212, and the insulating curtain 113 abuts against the insulating sleeve 222 and / or the connecting piece 221; wherein, when no connecting piece 221 is connected to any position of the phase bar 112, the first opening 1112 corresponding to that position is completely blocked by the insulating curtain 113 to completely isolate the insulating bar 111. When a connecting piece 221 is connected to that position, the insulating curtain 113 abuts against the connecting assembly 22 to improve the insulation between the connecting piece 221 and the phase bar 112.

[0040] Further, the insulating curtain 113 may include a sub-curtain 1131 disposed at the first opening 1112 and connected to the top or bottom end of the first opening 1112. When the second end 2212 passes through the first opening 1112, the sub-curtain 1131 is pushed into the first receiving cavity 1111 by the second end 2212, and the sub-curtain 1131 abuts against the top surface of the insulating sleeve 222, or the top surface of the connecting member 221, or the bottom surface of the insulating sleeve 222, or the bottom surface of the connecting member 221, or the top surface of the insulating sleeve 222 and the top surface of the connecting member 221, or the bottom surface of the insulating sleeve 222 and the bottom surface of the connecting member 221 to isolate one side of the connecting member 221 in the up and down direction.

[0041] Further, the insulating curtain 113 may also include two sub-curtains 1131. Both of the two sub-curtains 1131 are disposed at the first opening 1112 and are respectively connected to the top and bottom ends of the first opening 1112. Both of the two sub-curtains 1131 close the first opening 1112 or jointly close the first opening 1112. The two sub-curtains 1131 respectively close a part of the first opening 1112. When the second end 2212 passes through the first opening 1112, both of the two sub-curtains 1131 are pushed into the first receiving cavity 1111 by the second end 2212. The two sub-curtains 1131 respectively abut against the top and bottom surfaces of the insulating sleeve 222, or the two sub-curtains 1131 respectively abut against the top and bottom surfaces of the connecting member 221, or the two sub-curtains 1131 respectively abut against the top and bottom surfaces of the insulating sleeve 222 and the top and bottom surfaces of the connecting member 221. Wherein, when both of the two sub-curtains 1131 close the first opening 1112, at this time, the width of the sub-curtain 1131 in the up and down direction is not less than the width of the first opening 1112 in the up and down direction, and one of the sub-curtains 1131 can completely cover the first opening 1112 to have better isolation. The two sub-curtains 1131 can also jointly close the first opening 1112. At this time, the width of the sub-curtain 1131 in the up and down direction is less than the width of the first opening 1112 in the up and down direction, and the two sub-curtains 1131 respectively close a part of the first opening 1112 to facilitate the connecting member 221 to push open the insulating curtain 113.

[0042] Further, the phase row 112 includes two clamping jaws 1121 oppositely arranged in the up and down direction. Both of the two clamping jaws 1121 are arranged towards the first opening 1112. The clamping jaw 1121 is provided with a clamping portion 11211. A clamping gap 1122 is formed between the clamping portions 11211 of the two clamping jaws 1121. One end of the connecting member 221 extends into the clamping gap 1122, and the top surface and the bottom surface of this end are respectively connected to the clamping portions 11211 of the two clamping jaws 1121. Wherein, the phase row 112 is set as a clamping jaw 1121 structure to facilitate the insertion of the second end 2212 into the clamping gap 1122 for connection. The second end 2212 of the connecting member 221 can be correspondingly set as a strip-shaped structure to further facilitate the insertion into the clamping gap 1122 for connection.

[0043] Furthermore, the clamping jaw 1121 is further provided with a guide surface 11212, the guide surface 11212 is located between the clamping portion 11211 and the first opening 1112, the distance between the guide surfaces 11212 of the two clamping jaws 1121 is greater than the width of the clamping gap 1122 along the up-down direction, and the distance between the guide surfaces 11212 of the two clamping jaws 1121 gradually increases from the clamping portion 11211 to the first opening 1112; the insulating assembly 11 further includes a clamping member 114, the clamping member 114 is sleeved on the phase row 112 away from the first opening 111 2, the clamping member 114 is connected to the two clamping jaws 1121, and the clamping member 114 is pressed on the side of the clamping jaw 1121 away from the other clamping jaw 1121, so that the clamping parts 11211 of the two clamping jaws 1121 have a tendency to approach each other; wherein the guide surface 11212 is used to facilitate the insertion of the second end 2212 into the clamping gap 1122, and before the second end 2212 is inserted into the clamping gap 1122, the width of the clamping gap 1122 along the vertical direction is smaller than the thickness of the second end 2212 along the vertical direction. In addition, the clamping member 114 is used to apply opposite pressures to the two clamping jaws 1121. When the second end 2212 is inserted into the clamping gap 1122, the width of the clamping gap 1122 along the vertical direction is smaller than the thickness of the second end 2212 along the vertical direction. In addition, the clamping member 114 is used to apply opposite pressures to the two clamping jaws 1121. When the second end 2212 is inserted between the two clamping parts 11211, the second end 2212 abuts against the guide surface 11212 of the two clamping jaws 1121 and moves to open the two clamping jaws 1121, so that the width of the clamping gap 1122 along the vertical direction becomes larger to be equal to the thickness of the second end 2212 along the vertical direction, and then the second end 2212 is located in the clamping gap 1122, and the clamping member 114 applies pressure to the two clamping jaws 1121, so that the two clamping parts 11211 abut against the top and bottom surfaces of the second end 2212, so as to realize the connection between the connecting member 221 and the row 112, when the second end 2212 is removed from the two clamping parts 11211 When the two clamping jaws 1121 are pulled out, the clamping piece 114 applies pressure to the two clamping jaws 1121, so that the two clamping parts 11211 are close to each other, so that the width of the clamping gap 1122 along the up-down direction is smaller than the thickness of the second end 2212 along the up-down direction. In addition, since the phase row 112 requires better conductivity and the clamping piece 114 needs to continuously apply pressure to the phase row 112, the phase row 112 can be made of copper, and the clamping piece 114 can be made of a metal material with a certain elasticity.
