Abstract
The utility model discloses an interlocking mechanism for protecting ground switch against faulty operation, comprising a lateral plate of switch cabinet and a back door plate of switch cabinet. The lateral plate of switch cabinet is provided with a support seat for fixing a main shaft of a ground switch on the lateral plate of switch cabinet. The main shaft of the ground switch is provided with a turn arm which forms an angle with the main shaft, the top of the turn arm is provided with a groove, and the top of the support seat is provided with a fixed base and a guide plate. A push plate and a locked plate are mounted on the fixed base through pin shafts, wherein the locked plate can be locked in the groove on top of the turn arm. A top plate passes through a hole in the guide plate to contact the push plate, and the top plate is covered by a spring. Adopting the special structure, the locked plate is level because of self weight when the back door plate of switch cabinet is open, and the turn arm is locked to stop the main shaft of the ground switch rotating, thereby achieving the goal that the ground switch can not be operated when the back door plate of switch cabinet is open, and ensuring personal safety and property safety.
Description
Technical field
The utility model relates to a kind of interlocking gear, especially relates to a kind of interlocking gear that prevents the earthed switch misoperation.
Background technology
The indoor HVAC switch cubicle has all obtained application more and more widely in every field such as power industry, industrial and mining enterprises, railway transportations as indispensable major control in the electric power system and protection equipment.High voltage ground switch is the critical elements in the switch cubicle, and its effect is bypass equipment or circuit, guarantees that they are ground connection when repair apparatus and circuit, so that guarantee personal safety.
According to the electric power requirement of shelter, the maintainer after service work is finished, all door-plates of off switch cabinet at first, disconnect earthed switch again after, just can send the electricity operation.Because many switch cubicles are in juxtaposition and form a system often, the operator is when switch cubicle front side operational grounding switch, whether the rear portion door-plate that can't confirm this switch cubicle is closed and is put in place, be easy to cause under the situation that the switch cubicle Rear Door is not closed, and mistake disconnects earthed switch, after switch cubicle send electricity like this, the person and property safety are brought major hidden danger.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of interlocking gear that prevents the earthed switch misoperation at problems of the prior art, its objective is to guarantee just can operate earthed switch under the situation that the switch cubicle Rear Door is closed.
The technical solution of the utility model is that this a kind of interlocking gear of earthed switch misoperation that prevents comprises switch cubicle side plate and switch cubicle Rear Door, on the switch cubicle side plate bearing is installed, the earthed switch main shaft is fixed on the switch cubicle side plate by bearing, the connecting lever angled with the earthed switch main shaft is installed on the earthed switch main shaft, the top of connecting lever is provided with groove, the top of bearing is equipped with holder and guide plate, push pedal and jam plate are installed on the holder by bearing pin, jam plate can be stuck in the groove at connecting lever top, top board passes the hole in the guide plate, and can contact with push pedal, be with spring on the top board.
Described push pedal is fixedlyed connected with jam plate, is shaped as " L " shape, and bearing pin is fixed on the junction of push pedal and jam plate, and push pedal and jam plate can rotate around bearing pin.
The middle part of described push rod is equipped with spring pivot, and spring pivot is positioned at the inboard of switch cubicle side plate, and spring is between spring pivot and guide plate.
Describedly positioning sleeve is installed near switch spindle and bearing junction.
A kind of interlocking gear of earthed switch misoperation that prevents with above-mentioned special construction has the following advantages:
1, this interlocking gear is when the switch cubicle Rear Door is opened, jam plate pins connecting lever because own wt can be horizontal, and the earthed switch main shaft can't be rotated, thereby can't the operational grounding switching purposes when having realized that the switch cubicle Rear Door is not closed, guaranteed the person and property safety.
2, this a kind ofly prevents that the interlocking gear manufacture craft of earthed switch misoperation is simple, easy for installation, uses reliably, and effect is obvious, has the excellent popularization using value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is in the structural representation of open mode for switch cubicle Rear Door in the utility model.
Fig. 2 is in the structural representation of closed condition for switch cubicle Rear Door in the utility model.
In Fig. 1～2,1: the switch cubicle side plate; 2: the switch cubicle Rear Door; 3: bearing; 4: the earthed switch main shaft; 5: connecting lever; 6: holder; 7: guide plate; 8: push pedal; 9: jam plate; 10: bearing pin; 11: push rod; 12: spring; 13: spring catch; 14: positioning sleeve.
Embodiment
Figure 1 shows that switch cubicle Rear Door in the utility model is in the structural representation of open mode, Fig. 2 is in the structural representation of closed condition for switch cubicle Rear Door in the utility model.By Fig. 1 and Fig. 2 in conjunction with as can be known, this interlocking gear comprises switch cubicle side plate 1 and switch cubicle Rear Door 2, bearing 3 is installed on the switch cubicle side plate 1, earthed switch main shaft 4 is fixed on the switch cubicle side plate 1 by bearing 1, near switch spindle 4 and bearing 1 junction positioning sleeve 14 is installed, the connecting lever 5 angled with earthed switch main shaft 4 is installed on the earthed switch main shaft 4, the top of connecting lever 5 is provided with groove, the top of bearing 1 is equipped with holder 6 and guide plate 7, push pedal 8 and jam plate 9 are installed on the holder 6 by bearing pin 10, push pedal 8 is fixedlyed connected with jam plate 9, is shaped as " L " shape, and bearing pin 10 is fixed on the junction of push pedal 8 and jam plate 9, push pedal 8 and jam plate 9 can rotate around bearing pin 10, jam plate 9 can be stuck in the groove at connecting lever 5 tops, and top board 11 passes the hole in the guide plate 7, and can contact with push pedal 8, be with spring 12 on the top board 11, the middle part of push rod 11 is equipped with spring pivot 13, and spring pivot is positioned at the inboard of switch cubicle side plate 1, and spring 12 is between spring pivot 13 and guide plate 7.
When earthed switch is in combined floodgate, when switch cubicle Rear Door 2 was in open mode, jam plate 9 pinned connecting lever 5 because own wt is horizontal, earthed switch main shaft 4 can't be rotated, can't the operational grounding switching purposes when having reached switch cubicle Rear Door 2 and not closing.
When earthed switch is in combined floodgate, when switch cubicle Rear Door 2 was in closed condition, switch cubicle Rear Door 2 was pushed down push rod 11, it is moved right, withstand push pedal 8 jam plate 9 is rotated, connecting lever 5 release from jam plate 9, earthed switch main shaft 4 can freely rotate, and can carry out the operational grounding switch.Thereby can't the operational grounding switching purposes when having realized that switch cubicle Rear Door 2 is not closed, guaranteed the person and property safety.
