Abstract
A limiting plate for an operating mechanism of a switch cabinet comprises a square hole in the middle, wherein a blocking surface is arranged on the circumference of the limiting plate, and the limiting plate for the operating mechanism of the switch cabinet is characterized in that an outward 45-degree angle is formed between the blocking surface and a centripetal line. The original limiting plate is improved and used on the operating mechanism of the switch cabinet, the structure is simple, the reliability is high, and the misoperation prevention is greatly improved.
Description
Technical field
The utility model relates to switch cubicle operating mechanism technical field, relates in particular to the spare and accessory parts that a kind of switch cubicle operating mechanism is used.
Background technology
The switch cubicle operating mechanism is used for switch cubicle, as the device of actuating isolating switch, earthed switch, and can satisfy isolating switch, earthed switch and circuit breaker " anti-mutually " interlock requirement each other.The interlocking of switch cubicle is to guarantee the power network safe operation, guarantee equipment and personal safety, prevent the important measures of misoperation.The switch cubicle operating mechanism is made up of main parts size such as framework, pedestal, main shaft, limiting plate, connecting lever, handle and connecting rods; Wherein connecting lever is connected with isolating switch, earthed switch through bracket, connecting rod, and circuit breaker is interlocked through operating mechanism and isolating switch, earthed switch.
As shown in Figure 1, limiting plate is that the middle part is cubic hole, and the circumference of limiting plate is provided with retaining actinal surface 2, is enclosed within on the suitable main shaft 4; Rotating spindle 4, main shaft 4 drives limiting plate and rotates, when forwarding spacing position to; The retaining actinal surface 2 of limiting plate withstands on the baffle plate 3 of frame, and the retaining actinal surface 2 sensing centers of circle on the present limiting plate are when reality is used; Withstand on the baffle plate on the angle of retaining actinal surface 2, when the operator exerts oneself rotating spindle, can occur; The circumference of limiting plate withstands on the baffle plate, and main shaft turns over required spacing position, causes potential safety hazard to occur.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective, and a kind of limiting plate is provided, and its spacing performance is good, guarantees the anti-error performance of switch cubicle operating mechanism, and is safe and reliable.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme to be:
The limiting plate that a kind of switch cubicle operating mechanism is used comprises the middle part for cubic hole, and the circumference of limiting plate is provided with the retaining actinal surface, it is characterized in that keeping off actinal surface and is outside miter angle with line entad.The utility model has changed original retaining actinal surface and has pointed to the center of circle, and the retaining actinal surface is outside miter angle with line entad, when specifically using; Rotating spindle, main shaft drives limiting plate and rotates, when forwarding spacing position to; Because the retaining actinal surface is outside miter angle with line entad, the retaining actinal surface overlaps with the baffle-panels of frame, keeps off actinal surface and withstands on the baffle plate; When the operator exerts oneself rotating spindle like this; Because the retaining actinal surface withstands on the baffle plate, just main shaft can not occur turns over required spacing position, and its security performance is greatly enhanced.
The beneficial effect of the utility model is: the utility model improves original limiting plate, is used on the switch cubicle operating mechanism, and is simple in structure, good reliability, and anti-error performance increases greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Sketch map when Fig. 1 is the use of prior art limiting plate.
Fig. 2 is the structural representation of the utility model embodiment.
Sketch map when Fig. 3 is the use of the utility model embodiment.
Among the figure: 1, cubic hole 2, retaining actinal surface 3, baffle plate 4, main shaft.
Embodiment
Among Fig. 2, the limiting plate that a kind of switch cubicle operating mechanism is used comprises the middle part for cubic hole 1, and the circumference of limiting plate is provided with retaining actinal surface 2, and retaining actinal surface 2 is outside miter angle with line entad.
The utility model has changed original retaining actinal surface and has pointed to the center of circle, and retaining actinal surface 2 is outside miter angle with line entad, during use; As shown in Figure 3, rotating spindle 4, main shaft 4 drives limiting plate and rotates; When forwarding spacing position to, because retaining actinal surface 2 is outside miter angle with line entad, retaining actinal surface 2 overlaps with 3 on the baffle plate of frame; Retaining actinal surface 2 withstands on the baffle plate 3, when the operator exerts oneself rotating spindle like this, because retaining actinal surface 2 withstands on the baffle plate 3; Just main shaft can not occur turns over required spacing position, and the gas security performance is greatly enhanced.
Claims (1)
1. limiting plate that the switch cubicle operating mechanism is used comprises that the middle part is cubic hole, and the circumference of limiting plate is provided with the retaining actinal surface, it is characterized in that keeping off actinal surface and is outside miter angle with line entad.
