Abstract
The utility model relates to an impact type high-voltage movable substation contact device, and particularly to an impact type high-voltage movable substation contact device for a downhole high-voltage movable substation head of a coal mine. The utility model aims to settle a technical problem of providing the high-voltage movable substation contact device which can switch on and switch off a circuit breaker safely and reliability. An adopted technical solution of the impact type high-voltage movable substation contact device is characterized in that: a static contact of the circuit breaker in the high-voltage movable substation is fixedly arranged on a static contact fixing board, and a dynamic contact of the circuit breaker is arranged on a circuit breaker frame which can move horizontally. The impact type high-voltage movable substation contact device is suitable for the coal mine field.
Description
Technical field
The utility model collision type high pressure moves change contact apparatus, is specifically related to a kind of colliery down-hole high pressure and moves change head collision type contact device for circuit breaker.
Background technology
At present, it is to adopt guillotine type in the majority that conventional high pressure moves a change core body installation, in shell chamber, inner region of interest is installed stepping brake knife switch, two ends are connected in circuit breaker and binding post with wire respectively, by the folding of plug-in strip, control high pressure and move the break-make that becomes head, the poor stability that the maximum drawback of this method is plug-in strip contact, easily causes and closes a floodgate not in place and produce spark, this needs occasion for colliery etc. is breakneck, has great potential safety hazard.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: provide a kind of colliery high pressure that can safe and reliable deciliter circuit breaker to move change contact apparatus.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: collision type high pressure moves change contact apparatus, the fixed contact that described high pressure moves the circuit breaker that becomes inner is fixedly installed on fixed contact fixed head, and the moving contact of circuit breaker is arranged on the circuit breaker vehicle frame that can move horizontally.
The bottom sides of described circuit breaker vehicle frame is provided with U-shaped hook, in described U-shaped hook, be provided with the cylinder axis that can slide in U-shaped hook, described cylinder axis is hinged on one end of bent axle, the other end of described bent axle is hinged on axle bed, the middle part of bent axle and one end of brace are hinged, the other end of described brace and one end of pull bar are hinged, and described pull bar is horizontally disposed with, and the other end of pull bar is connected with Handle axis by connecting rod.
Described circuit breaker bottom of frame is provided with roller.
The beneficial effect that the utility model compared with prior art has is: the utility model can be safely and reliably by contact of breaker deciliter, has avoided closing a floodgate not in place and produces spark, has improved the safe class of coal mine equipment, meets coal mine explosion-proof requirement; Whole apparatus structure is succinct, easy to use, practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of bent axle in the utility model;
Fig. 3 is the end view of Fig. 2;
In figure: 1 is that fixed contact fixed head, 2 is that fixed contact, 3 is that moving contact, 4 is that circuit breaker, 5 is that U-shaped hook, 6 is that pull bar, 7 is that Handle axis, 8 is that connecting rod, 9 is that bent axle, 10 is that shaft-cup plate, 11 is that axle bed, 12 is that circuit breaker vehicle frame, 13 is that cylinder axis, 14 is that brace, 15 is roller.
Embodiment
As shown in Figure 1 to Figure 3, the utility model collision type high pressure moves change contact apparatus, the fixed contact 2 that described high pressure moves the circuit breaker 4 that becomes inner is fixedly installed on fixed contact fixed head 1, the moving contact 3 of circuit breaker 4 is arranged on the circuit breaker vehicle frame 12 that can move horizontally, described fixed contact 2 is identical with the height of moving contact 3, quantity is identical, generally adopts one group 6, circuit breaker 4 with moving horizontally of circuit breaker vehicle frame 12 realize with fixed contact 2 deciliter.
Described circuit breaker vehicle frame 12 bottoms are provided with roller 15, the bottom sides of circuit breaker vehicle frame 12 is provided with U-shaped hook 5, in described U-shaped hook 5, being provided with can be at the cylinder axis 13 of U-shaped hook 5 interior slips, described cylinder axis 13 is hinged on one end of bent axle 9, the other end of described bent axle 9 is hinged on axle bed 11, shaft-cup plate 10 is set on axle bed 11, one end of the middle part of bent axle 9 and brace 14 is hinged, one end of the other end of described brace 14 and pull bar 6 is hinged, described pull bar 6 is horizontally disposed with, and the other end of pull bar 6 is connected with Handle axis 7 by connecting rod 8.
Above-mentioned Handle axis 7 is rotated around axle bed 11 by connecting rod 8 and pull bar 6 traction bent axles 9, with the hinged cylinder axis 13 of bent axle 9 in the interior slip of U-shaped hook 5, thereby drive U-shaped hook 5 to move, make fixed contact 2 and moving contact 3 deciliters, can be safely and reliably by contact of breaker deciliter, avoided closing a floodgate not in place and produced spark, having improved the safe class of coal mine equipment, having met coal mine explosion-proof requirement.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make various variations.
