Technical field
The present invention relates to a kind of high-voltage rotary current-collector.
Background technology
Large power-consuming equipment often uses the high pressure input of 6-10kV, to reduce the electric current in the circuit.And portable, self can make the large power-consuming equipment of 360 degree rotations with central shaft, like the harbour loop wheel machine, mine excavator for a kind of revolvable high powered device of high pressure input needs, can satisfy the need for electricity of equipment.
Summary of the invention
The present invention wants the technical solution problem to provide a kind of high-voltage rotary current-collector.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of high-voltage rotary current-collector is characterized in that, comprises fixed disk mechanism and rotating disk mechanism;
Described fixed disk mechanism comprises fixing dish, the fixing lower wall support bar vertical with Duo Gen gone up, fixing go up to coil with fixing lower wall be fixedly connected through support bar; Described fixing go up dish and fixedly lower wall be circulus;
Described rotating disk mechanism comprises that rotation goes up many rotating disk poles of dish, rotation lower wall, 4 high pressure copper rings and vertical direction, coils rotation in, 4 high pressure copper rings and rotate lower wall and be arranged on from top to bottom on the described rotating disk pole; Each high pressure copper ring is provided with a high pressure inlet wire binding post; The junction of 4 high pressure copper rings and insulation strut is provided with the insulation ring set;
Described rotating disk mechanism is embedded in the fixed disk mechanism;
The brush that vertically is respectively arranged with 4 covers and described 4 same horizontal levels of high pressure copper ring on the described support bar receives electrical mechanisms; Described brush receives electrical mechanisms to comprise collets, brush and high-voltage terminal binding post; Brush and high-voltage terminal binding post are arranged on the collets; Collets are fixed on the support bar; Brush one end and high pressure copper ring form friction-type and electrically contact, and the other end is connected with the high-voltage terminal binding post.
Support bar is 4, and rotating disk pole is 3.
The beneficial effect of the invention:
It is need receive on the plant equipment of electricity that this rotary current-collector is installed.Outside fixed disk mechanism is motionless, and inner rotating disk mechanism can rotate, thereby plant equipment can receive from the high-voltage terminal binding post in the outer disk mechanism.
High-voltage rotary current-collector of the present invention gets at the rotating disk bottom external cable internally, is connected on the high pressure copper ring; The outside is a fixed frame, does sliding contact with brush and charged high pressure copper ring, and conduction current makes inside cable connect with brush, and high voltage source is transported on the power consumption equipment, has solved high-pressure rotary thus and has received electric problem.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of high-voltage rotary current-collector is characterized in that, comprises fixed disk mechanism and rotating disk mechanism;
Described fixed disk mechanism comprises fixing dish 2, the fixedly lower wall 10 and 4 vertical support bars 12 gone up, fixing go up to coil with fixing lower wall be fixedly connected through support bar; Described fixing go up dish and fixedly lower wall be circulus;
Described rotating disk mechanism comprises that rotation goes up 3 rotating disk poles 13 of dish 1, rotation 9,4 high pressure copper rings 4 of lower wall and vertical direction, coils rotation in, 4 high pressure copper rings and rotate lower wall and be arranged on from top to bottom on the described rotating disk pole; Each high pressure copper ring is provided with a high pressure inlet wire binding post 11; The junction of 4 high pressure copper rings and rotating disk pole is provided with insulation ring set 7;
Described rotating disk mechanism is embedded in the fixed disk mechanism;
The brush that vertically is respectively arranged with 4 covers and described 4 high pressure copper ring 4 same horizontal levels on the described support bar 12 receives electrical mechanisms; Described brush receives electrical mechanisms to comprise collets 6, brush 5 and high-voltage terminal binding post 8; Brush and high-voltage terminal binding post are arranged on the collets; Collets are fixed on the support bar; Brush one end and high pressure copper ring form friction-type and electrically contact, and the other end is connected with the high-voltage terminal binding post.
Rotating disk comprises rotation upward dish 1 and rotation lower wall 9, with three rotating disk support bars, 13 fixing three groups of circle covers 3 that insulate, high pressure copper ring 4, insulation ring set 7, ground wire copper ring; There is high pressure inlet wire binding post 11 the copper ring inboard, and whole rotating disk mechanism can the rotation arbitrarily of 360 degree.Fixing going up coils 2 with fixedly lower wall 10 is fixing through four axles (being support bar 12); With the corresponding position of high pressure copper ring on symmetry be equipped with four groups of collets 6; Collets central authorities are brushes 5, and there is high-voltage terminal binding post 8 the brush end, thereby accomplish the function that rotation receives electricity.
The external high pressure cable gets into from current collector bottom centre hole, and threephase cable (three-phase and four-line) is connected on respectively on the inboard high pressure inlet wire binding post of three high pressure copper rings; Isolate with insulating case respectively between the high pressure copper ring, to satisfy the electric insulation requirement of high pressure; The high pressure copper ring, three groups of insulation ring sets are separately fixed on three rotating disk support bars, the rotating disk support bar up and down with last rotating disk and lower rotating disc positioning and fixing.
