Abstract
The utility model relates to a high-voltage switch cabinet static and dynamic contact curtain folding mechanism in high-voltage transmission and distribution control facilities, wherein a pushing mechanism is installed in a switch cabinet body for pushing a dolly to advance and retreat, the left side of the front end of a breaker dolly is provided with a push-plate, the left side of the cabinet body is provided with a striking plate assembly, a driver plate, a trough plate, an eccentric plate assembly and a drive mechanism consisting of several groups of chain wheel drive mechanisms, and the rear side of the cabinet body is provided with a static contact cover. When the breaker dolly is pushed to advance by the pushing mechanism, striking plate assembly, the driver plate, the trough plate, the eccentric plate assembly and several groups of the chain wheel drive mechanisms transfer power mutually to drive an upper and a lower curtain assemblies respectively to synchronously open in the upper and the lower directions. The transfer dolly continues to advance after the curtains are opened, and the drive mechanism is static.
Description
Technical field
The utility model relates to a kind of moving/fixed contact curtain door folding mechanism for high-tension switch cabinet in the high pressure power transmission and distribution control device.
Background technology
The reliability of high pressure power transmission and distribution control device middle-high voltage switch moving/fixed contact curtain door folding is a very important technical indicator, and it is related to maintainer's personal safety.In the prior art, curtain door open-and-close mechanism adopts two fork lever constructions of cultrating, and does not have glissando, is prone to bounce-back after curtain door opening and closing movement is finished, and causes the folding of curtain door not in place.In original mechanism, different circuit breaker dollies can not be general, and folding is unreliable, and fault easily gets stuck midway.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of reliable moving/fixed contact curtain door folding mechanism for high-tension switch cabinet is provided, and requires mechanism's operation unobstructed.
Moving/fixed contact curtain door folding mechanism for high-tension switch cabinet of the present utility model, pushing mechanism 2 is installed in switch cabinet body is promoted the dolly advance and retreat, push pedal 3 is installed in left side at circuit breaker dolly 1 front end, and one group of transmission mechanism is installed on the cabinet left side, and stationary contact head-shield 12 is installed in the cabinet back.When circuit breaker dolly 1 is promoted to advance by pushing mechanism 2, little axle in the push pedal 3 enters the U groove of swinging plate assembly 4, promote swinging plate assembly 4 around the center rotation, one end of swinging plate assembly 4 drive driver plates 5 is moving linearly forward, the other end of driver plate 5 is fixedlyed connected with frid 6, promote frid 6 along travelling forward by four bearing limited posts 16, eccentric disk assembly 7 has one little Z-shaped groove that is positioned on the frid 6, move upward along Z-shaped groove, eccentric disk assembly 7 is along with little axle rotates, driving chain gear transmission 3 combinations 8 rotates, chain gear transmission 2 combinations 10 that chain gear transmission 3 combinations 8 drive when rotating on the chainlet wheel shaft 9 are rotated, chain gear transmission 2 combinations 10 are overturn downwards by lower shutter assembly 11, drive chain gear transmission 1 combination 13 interlocks simultaneously and go up upwards upset of curtain door assembly 14, in the realization lower shutter respectively up and down both direction open synchronously.After the curtain door was opened, the U groove that the little axle in the push pedal 3 breaks away from swinging plate assembly 4 was along with dolly 1 moves on, and swinging plate assembly 4 has a fixed supporting seat 1 tightly to prop up swinging plate assembly 4, prevents that swinging plate assembly 4 is rotated further.
The utility model switch is flexible, simple and reliable.When switch cubicle vacuum circuit-breaker dolly moved forward, two curtain doors can be rapidly respectively towards both direction unlatching and self-locking synchronously up and down, and the circuit breaker dolly can advance to till the dynamic/static contact engagement; When the circuit breaker dolly withdrawed from the stationary contact head-shield to home, the curtain door was just slowly closed, and did not have impact phenomenon.The maintenance of circuit breaker dolly, in the time of need removing equipment, last lower shutter is opened and self-locking, protection attendant personal safety.
Moving/fixed contact curtain door folding mechanism for high-tension switch cabinet of the present utility model can be produced in batches in advance, and interchangeability is strong, change simply, Installation and Debugging are convenient, and most parts are standard component, can improve precision, reduce cost, and not have special supporting requirement with other parts of switchgear.Last lower shutter is two reverse turn unlatchings up and down respectively, have strengthened the circuit breaker dolly when the service position, the electric clearance of the exposed energized conductor of curtain door and circuit breaker, the security reliability when having guaranteed the switchgear operation.
