Abstract
The utility model discloses a grounding device for a switch cabinet. The grounding device for the switch cabinet comprises a fixed contact, a grounding knife switch, an insulator and a rotation shaft, wherein the insulator is fixed on the cabinet body; the fixed contact is fixed on the insulator; the rotation shaft is pivoted on the cabinet body; one end of the grounding knife switch is sleeved on the rotation shaft and can move relatively to the rotation shaft; a driving plate is further fixed on the rotation shaft; one end of the grounding knife switch, which is connected with the rotation shaft, is further provided with a driving pin parallel to the rotation shaft; a positioning pin parallel to the rotation shaft is arranged at a position of the cabinet body, which is close to the rotation shaft; a positioning groove arranged on the outer circumference of one end through which the grounding knife switch is connected with the rotation shaft is matched with the positioning pin on the cabinet body; the lower end of one compression spring is hinged with the cabinet body, and the upper end of the compression spring is hinged with the driving pin; a driving groove arranged on the outer circumference face of a driving plate is matched with the driving pin; and when the rotation shaft drives the grounding knife switch to rotate, the positioning pin can limit the both ends of the positioning groove. The grounding device for the switch cabinet provided by the utility model has the advantages of simple operation, reliable grounding and low manufacturing cost.
Description
Technical field
The utility model relates to switch cubicle manufacturing technology field, the earthing device that especially a kind of switch cubicle is used.
Background technology
Indoor steel-clad switchbox is the widely used controller switching equipment of electric power system, according to working specification, when switch cubicle overhauls, its fixed contact that is connected with bus is wanted reliable ground, present switch-cabinet grounding scheme mainly contains following several: the one, and adopt conventional earth connection directly to be affiliated on fixed contact, but thisly articulate unreliablely, be prone to and break away from and the situation of imperfect earth; The 2nd, directly articulate earth connection on bus, but therefore the class switch cubicle is totally enclosed type, need open bus-bar room, operates cumbersome; The 3rd, adopt earth handcart, but the earth handcart complicated structure, operation is also complicated, and manufacturing cost is high.
The utility model content
The technical problems to be solved in the utility model is to provide the earthing device that a kind of switch cubicle is used, and is simple to operate, and ground connection is reliable, and low cost of manufacture.
for achieving the above object, the technical solution of the utility model is: the earthing device that a kind of switch cubicle is used, comprise fixed contact, grounding switch, insulator, rotating shaft, insulator is fixed on cabinet, fixed contact is fixed on insulator, rotating shaft is articulated on cabinet, one end of grounding switch is enclosed within rotating shaft and with rotating shaft and can relatively rotates, also fix a drive plate in rotating shaft, grounding switch is connected with rotating shaft and also is provided with a drive pin that parallels with rotating shaft on an end, be provided with an alignment pin that parallels with rotating shaft at cabinet near rotating shaft place, be connected with the rotating shaft outer peripheral face of an end of grounding switch is provided with detent and matches with described alignment pin on cabinet, the lower end of one Compress Spring is hinged on cabinet, the upper end of Compress Spring is hinged on described drive pin, the outer peripheral face of drive plate is provided with the driving groove and matches with described drive pin, when rotating shaft drives the grounding switch rotation by drive plate, described detent can move along described alignment pin, described alignment pin can engage or break away from fixed contact with the mutually spacing grounding switch that makes in the two ends of described detent with fixed contact.
Preferred described detent is the circular arc type groove.Facilitate alignment pin to move along described detent.
Further improve, guide post is equipped with in the centre of described Compress Spring.Can make compression and the stretching of Compress Spring more reliable.
Further improve, the middle part of described grounding switch is by soft wire ground connection.Facilitate the activity of grounding switch.
The utility model is due to grounding switch being set, grounding switch be articulated in that on cabinet, a rotating shaft fixes, rotating shaft just can drive grounding switch and matches with fixed contact and be grounded like this, simultaneously rotating shaft is under the effect of Compress Spring spring force and be arranged on alignment pin on cabinet and the detent on grounding switch and realize location fast under coordinating, therefore simple to operate, ground connection is reliable; The utility model is relatively simple for structure in addition, low cost of manufacture.
Description of drawings
Fig. 1 is that the utility model grounding switch engages front view with fixed contact;
