Description
Technical field
The present invention relates to a kind of high-voltage electrical apparatus switch, especially relate to a kind of decelerator of high-voltage electrical apparatus switch.
Background technology
In electric power system, especially high voltage power transmisson system in order to guarantee to import safety, all adopts high voltage isolator to carry out the transmission of electricity circuit control.This high voltage isolator generally all is provided with decelerator, and decelerator is accomplished through worm gear, worm structure and slowed down, and carries out spacing through position-limit mechanism to the rotational angle of worm gear.Because this position-limit mechanism has certain impact in spacing process,, influenced its useful life so in long use, can cause bigger injury to deceleration.Like publication number is that the Chinese patent of CN 2484629 discloses a kind of motor operating mechanism that is used for high voltage isolator, comprises motor, reducing gear, support, control apparatus, binding post, auxiliary switch, crank, casing.Its reducing gear is made up of hermetic gear reduction unit and hermetic worm reducer, and both are through a gusset piece, with securing member be linked together.This structure is not controlled in the impact to decelerator, so its easy ageing in use.Publication number is that the Chinese patent of CN 2909496 discloses a kind of isolating switch that has gravity balance device.Comprise every have mutually two fixing static contact and insulation pillars and a moving contact insulation column that is arranged between the two static contact and insulation pillars; The top of static contact and insulation pillar is equipped with fixed contact; The top of moving contact insulation column is equipped with gear box, is provided with the power output shaft of level in the gear box, and connecting rod is installed on the power output shaft; The top of connecting rod has moving contact, and buffer-type gravitational equilibrium device is installed between gear box and connecting rod.Buffer-type gravitational equilibrium device is installed between the connecting rod and gear box of isolating switch, utilizes the elasticity of spring to overcome connecting rod weight, help to improve just-off speed, alleviate the impulsive force when closing a floodgate.This structure has an external buffer unit, but it can't accurately control from the impact in the decelerator, and therefore, its protective effect to the position-limit mechanism in the decelerator is very limited.
Summary of the invention
The present invention mainly is that the stopping means that solves the decelerator of existing in prior technology high-voltage electrical apparatus switch is hit and the technical problem of accelerated ageing etc. easily; Provide a kind of effectively buffering stop block suffered impact, thereby prolong the decelerator of the high-voltage electrical apparatus switch in its useful life.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of decelerator of high-voltage electrical apparatus switch; Comprise casing, controlling organization, worm gear, worm screw, worm gear is located on the worm-wheel shaft, and casing is provided with box flange; It is characterized in that described worm-wheel shaft is provided with a limiting plate; Limiting plate is provided with spacing preiection, and this spacing preiection is corresponding with the guide vane end stop on being located at box flange, and described spacing preiection is being provided with buffer unit with the guide vane end stop corresponding position.When the limiting plate convexity with and the buffer unit that go up to be provided with turn to the dead-centre position, promptly buffer unit contacts with guide vane end stop, then the spiral shell wheel stops operating, suffered impact obtains cushioning because of the existence of buffer unit in this process.
As preferably; Described buffer unit is made up of removable pin and compression spring, and described removable pin matches with a pin-and-hole of being located on the limiting plate, and the two ends of removable pin are equipped with spacing head; Described compression spring is located on the removable pin, and is between spacing head and the pin-and-hole.Removable pin can be in pin-and-hole axial translation; Can directly touch with guide vane end stop at the spacing head of removable pin, in contact process, axial translation can take place; Because the compression spring is located between spacing head and the pin-and-hole, the process of being impacted in the contact process of removable pin and guide vane end stop plays cushioning effect.
As preferably, the spacing head in the two ends of described removable pin and pin-and-hole between be equipped with the compression spring, the spacing head in the two ends of removable pin is corresponding with the two ends of guide vane end stop respectively.This structure makes worm gear can obtain the buffering of buffer unit at the dead point, both sides that forwards the design angle scope to, to reduce the suffered impact of decelerator.
As preferably, described compression spring is butterfly spring.Because the suffered impulsive force of the decelerator of high-voltage electrical apparatus switch is bigger, and the space that level is dashed is less, and that butterfly spring has rigidity is big, and the buffering vibration absorption ability is strong, can bear the characteristics of big load with small deformation.
As preferably, described guide vane end stop is an arcuate structure, and this arcuate structure is concentric with worm gear.This structure makes that the installing and locating of guide vane end stop is very convenient, can realize easily that the both sides of guide vane end stop all are in and the corresponding position of buffer unit.
As preferably, spacing to the angle of limiting plate between the described guide vane end stop two ends is 180 degree.Position-limiting action is played to the extreme position that limiting plate turns to both sides respectively in the two ends of guide vane end stop, and the rotational angle of limiting plate is limited in 180 degree.Realize this point, not only will consider the position and the length of guide vane end stop, also will consider the size of buffer unit.
As preferably, spacing to the angle of limiting plate between the described guide vane end stop two ends is 90 degree.Position-limiting action is played to the extreme position that limiting plate turns to both sides respectively in the two ends of guide vane end stop, and the rotational angle of limiting plate is limited in 90 degree.Equally, realize this point, not only will consider the position and the length of guide vane end stop, also will consider the size of buffer unit.
As preferably, described controlling organization comprises controller and control switch, and this controller is provided with a commutation circuit that is used for the Switching power line.In actual use; When power positive cathode connects inverse time; It is opposite that the rotation direction of decelerator is wanted, and its opposite rotation meeting causes beyond thought hitting to relevant device, sometimes even can cause the danger of circuit misconnection; This commutation circuit can be switched by the both positive and negative polarity to power supply under the situation of circuit reversal connection, the transmission line that this high-voltage electrical apparatus switch and this high-voltage electrical apparatus switch are controlled is protected realizing.
The beneficial effect that brings of the present invention is; The stopping means that has solved the decelerator of existing in prior technology high-voltage electrical apparatus switch is hit and the technical problem of accelerated ageing etc. easily; Realized the suffered impact of a kind of effectively buffering stop block; Thereby prolong the decelerator of the high-voltage electrical apparatus switch in its useful life, have safe, practical, reliable advantage simultaneously.
