Abstract
A secondary circuit controller of a switch cabinet comprises a spiral lead screw, wherein the spiral lead screw is fixed on an installing plate, one end of the spiral lead screw is connected with a driving motor of a three-station switch, the other end of the spiral lead screw is provided with a lead screw nut, the lead screw nut is movably connected with a spacing plate arranged on the installing plate via a transmission mechanism, the installing plate is provided with an auxiliary switch, the auxiliary switch is movably connected with a slide block, the installing plate is fixedly connected with a support, the support is fixedly connected with a microstroke switch, and a lead cable is connected with the microstroke switch and the auxiliary switch via cable plugs. The secondary circuit controller is simple and compact in structure, the cable plugs are used for connecting the cable, the second circuit is simplified, wiring is simple, test of the lead cable can be directly carried out at the cable plug positions, fault incidence rate is low, work reliability is high, and even if a fault occurs, fault detection and component replacement are convenient.
Description
Technical field
This is practical to relate to a kind of switch cubicle secondary circuit controller.
Background technology
Along with rapid economy development, in the industries such as electric power, track traffic, high-speed railway and petrochemical industry in each city or area, the use of C-GIS switch cubicle (Cubicle Gas-Insulated Switchgear) more and more widely.Be provided with three-station in the cabinet of C-GIS switch cubicle, isolating switch and earthed switch be combined into an integral body by three-station, a public moving contact, a public operating mechanism is realized three operating mode positions of He Zha – Ge Li – ground connection.Because C-GIS switch cubicle volume is less, existing switch cubicle secondary circuit controller architecture complexity, the components and parts that comprise are more, and each components and parts is distributed in the cabinet everywhere, wiring is complicated, trouble is installed, and it is big to take up room, and remaining space is little in the cabinet, the rate of breakdown height, functional reliability is low, and fault is unfavorable for the investigation of fault and the replacing of components and parts when taking place.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of wiring simple, and rate of breakdown is low, the switch cubicle secondary circuit controller that functional reliability is high.
The technical solution of the utility model is: it comprises helical screw, helical screw is fixed on the mounting panel, helical screw one end links to each other with the drive motors of three-station, the other end is provided with the feed screw nut, the feed screw nut flexibly connects by transmission mechanism and the limiting plate of being located on the mounting panel, described mounting panel is provided with auxiliary switch, auxiliary switch and slide block flexibly connect, mounting panel and support are connected, support and micro limit switch are connected, and leader cable is connected with auxiliary switch with micro limit switch by cable plug.
Described helical screw is fixed on the mounting panel by tapping screw.
Described transmission mechanism is provided with feed screw nut's locking device, helps guaranteeing the accurate motion of auxiliary switch and micro limit switch.
When the drive motors of three-station started, three-station was in closing position, and helical screw is in the initial point position; After starting drive motors, drive motors drives helical screw and clockwise rotates, helical screw obtains actuating force from drive motors, helical screw passes to the feed screw nut with actuating force, the feed screw nut drives the limiting plate motion, and when helical screw rotation 23.75 was spent, drive motors shut down, at this moment, three-station is in the isolated location; Change the operating state of micro limit switch and auxiliary switch, leader cable sends signal and indications such as connection, disjunction, dropout, and drive motors starts once more, drives helical screw and is rotated counterclockwise, when helical screw is rotated counterclockwise 23.75 when spending, three-station is in earthing position; Realize three operating mode positions of He Zha – Ge Li – ground connection thus.
The utility model is simple in structure, compact, adopts connected mode under the cable that connects by cable plug, helps simplifying secondary circuit, and wiring is simple, and can directly carry out the test of leader cable from cable plug, and rate of breakdown is low, the functional reliability height; Even when fault takes place, also be beneficial to the investigation of fault and the replacing of components and parts.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
