Abstract
The utility model relates to an interlocking mechanism for preventing an error operation of a grounding switch of a metalclad withdraw switchgear, which can effectively prevent operators from mistakenly operating the grounding switch when the switch is electrified. The interlocking mechanism for preventing the error operation of the grounding switch has the characteristics of simple structure and convenience in use. The interlocking mechanism adopts the technical scheme that the interlocking mechanism for preventing the error operation of the grounding switch is characterized in that the interlocking mechanism comprises a bending plate for stopping an operation hole of the grounding switch and a locking plate fixed on a panel of a middle cabinet and provided with a lock hole; and one end of the bending plate is hinged on the panel of the middle cabinet while the other end of the bending plate is locked on the locking plate through a lockset. Moreover, the lockset is a padlock.
Description
Technical field
The utility model relates to the mid-cabinet in the electric power system, is specifically related to a kind of interlocking device that is used to prevent the misoperation of mid-cabinet earthed switch.
Background technology
Mid-cabinet is the abbreviation that the armouring type is removed the middle metal enclosed switchgear.Mid-cabinet generally all satisfies the requirement of " five is anti-" interlocking (to be had only when earthed switch is in gate-dividing state; Circuit breaker cart could move to the service position from disconnection/test position; Only when circuit breaker cart is in disconnection/test position; Earthed switch just can close a floodgate), effectively prevent the charged misoperation of operating personnel.But, also usually there are operating personnel not knowing under the situation of equipment running status operational grounding switch by force, cause serious accident generations such as charged mistake splice grafting ground switch.How preventing operating personnel's misoperation earthed switch, is producer's urgent problem.
The utility model content
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology; A kind of interlocking device that prevents the earthed switch misoperation is provided; This interlocking device should be able to prevent the charged misoperation earthed switch of operating personnel effectively, and has characteristics simple in structure, easy to use.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of interlocking device that prevents the earthed switch misoperation; It is characterized in that: said interlocking device comprises a bent plate that is used to block the earthed switch handle hole; And be fixed on the mid-cabinet panel and be shaped on the jam plate of lockhole; One end of said bent plate is hinged on the panel of mid-cabinet, and the other end is locked on the said jam plate through lockset.
Said lockset is a padlock.
The beneficial effect of the utility model is: the utility model blocks the earthed switch handle hole through bent plate, and locks bent plate with lockset, could operate earthed switch after making operating personnel have only padlock opened, and prevents the generation of misoperation effectively.And the utility model is simple in structure, and easy to use, cost of manufacture is lower, but large tracts of land is promoted.

Fig. 4 is the perspective view of jam plate in the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, the described a kind of interlocking device that prevents the earthed switch misoperation of the utility model comprises bent plate 1 (can adopt iron plate making), jam plate 3 and lockset.On the panel 4 of mid-cabinet, its plate face is vertical with the panel of mid-cabinet, is shaped on padlock hole 5 on this jam plate through screw for said jam plate.Said bent plate is used to block earthed switch handle hole 6 (can block fully, also can block the overwhelming majority of handle hole, prevent that staff from inserting), and the width of bent plate and the diameter of this earthed switch adapt, bent plate length 8-15cm (specifically confirming according to actual conditions); The two ends of bent plate all curve the right angle, and an end is hinged on through hinge 2 on the panel of mid-cabinet (routine techniques does not describe in detail), and the other end is parallel with said jam plate and be shaped on the lockhole corresponding with jam plate.Said lockset is locked at bent plate on the jam plate.
Described lockset can be the padlock (low price, easy to use) of outsourcing, and also other coded locks of buyable or electric control lockset are specifically confirmed according to actual conditions.Clean and tidy for drawing, lockset omits and does not draw among the figure.Said hinge buyable obtains.
Claims (2)
1. interlocking device that prevents the earthed switch misoperation; It is characterized in that: said interlocking device comprises a bent plate (1) that is used to block earthed switch handle hole (6); And be fixed on the jam plate (3) that lockhole (5) were gone up and be shaped on to mid-cabinet panel (4); One end of said bent plate is hinged on the panel of mid-cabinet, and the other end is locked on the said jam plate through lockset.
2. a kind of interlocking device that prevents the earthed switch misoperation according to claim 1 is characterized in that: said lockset is a padlock.
