The mechanical locking structure provided by the utility model has the advantages of being convenient for opening and closing of the rear cabinet door, preventing from entering live interval by error, and being simple, convenient and safe to operate by operators.
Description
Technical field
The utility model belongs to the switch cubicle field, relates to a kind of handcart type high-voltage switch cabinet, especially relates to a kind of mechanical latching structure of handcart type high-voltage switch cabinet.
Background technology
At present, in the 3-10kv distribution system at all kinds of power plants and alternating current station, use the handcart type high-voltage switch cabinet more; As accepting and the distribution electric energy; And to circuit implementation control, the usefulness of protection and monitoring generally all has " five is anti-" function; Like GC2-10 (F) the type handcart type high-voltage switch cabinet that Gansu Province Tianshui Changcheng Switchgear Factory produces, find in the practical application that it has following weak point.The one, prevent that the mistakenly entering charged chamber function from being to utilize the locking between ground connection cutter and switch rear cabinet door to realize; Owing to can't carry out electrical verification to conductor before opening rear cabinet door, with " electrical safe working order " (power plant and electric substation's electric part) the 73rd rules and regulations phasing contradiction; The 2nd, the power-plant operation personnel need often high voltage power to be shaken to survey insulation; Measure insulation and must open rear cabinet door; On the outlet cable end, carry out, if do not remove the locking of ground cutter to rear cabinet door, measuring a power insulation needs repeatedly twice ground cutter of drawing or the switch gear room that gets into violating the regulations; The 3rd, the switch cubicle rear cabinet door is a monolithic construction, and loading and unloading cabinet door is extremely required great effort, and is prone to make cabinet door upper edge to tilt, and touches the outlet conductor, causes three-phase shortcircuit,
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and it is convenient that the purpose of the utility model provides a kind of rear cabinet door switch, prevents mistakenly entering charged chamber, the handcart type high-voltage switch cabinet locking that the operations staff is easy to operate and safe.
The utility model is realized through following technical scheme:
This locking is made up of two parts: transmission mechanism and actuator, and running part is made up of side guide wheel, the horizontal pavilion of level, bearing under the dolly left side, and operating part is made up of vertical inserted link, spring, female receptacle, cabinet channel-section steel; Bearing is fixed on the switch cubicle base plate, and horizontal cross bar is fixed on the bearing through the axle on the bearing, can rotate up and down; Horizontal cross bar one end is oblique, contacts with advancing the car guide wheel, and the horizontal cross bar other end is connected with vertical inserted link lower end; Vertically on the inserted link spring is housed, vertically the inserted link upper end is passed the upper and lower side opening of cabinet channel-section steel and the hole on the female receptacle successively, and a hole is opened in the central dividing plate bottom of switch cabinet; Making under water, cross bar passes; Female receptacle is fixed on the rear cabinet door inboard, and rear cabinet door one side is lived with switch Huan and is connected, and the hand lock is contained in the rear cabinet door outside.
The beneficial effect of the utility model:
It is convenient to the utlity model has the rear cabinet door switch, prevents mistakenly entering charged chamber, makes operations staff's advantage easy to operate and safe.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the rear cabinet door structural representation of the utility model.
Among the figure, 1 be car switch, 2 for a left side down side guide wheel, 3 for bearing, 4 for horizontal cross bar, 5 for rear cabinet door, 6 for vertical inserted link, 7 for spring, 8 for the hand lock, 9 for female receptacle, 10 for cabinet channel-section steel, 11 be central dividing plate.
Embodiment
The utility model is specified with Fig. 2 according to accompanying drawing 1 below:
As shown in Figure 1, constitute the transmission mechanism of this locking by side guide wheel 2, horizontal cross bar 4, bearing 3 under the dolly left side, constitute the actuator of this locking by vertical inserted link 6, female receptacle 9, spring 7, cabinet channel-section steel 10.
Bearing 3 is welded on the switch cubicle base plate, and horizontal cross bar is fixed on the bearing 3 through the axle on the bearing 3, and the axle that horizontal cross bar 4 can bearing 3 is the center; Rotate up and down, horizontal cross bar 4 ends are processed oblique shape, contact with side guide wheel under the left side 2; The other end of horizontal cross bar 4 is connected with vertical inserted link 6; Vertically on the inserted link 6 spring 7 is housed, vertically inserted link 6 upper ends are passed hole and the hole on the female receptacle 9 of the upper and lower side of cabinet channel-section steel 10 successively, and a hole is opened in central dividing plate 11 bottoms of switch cabinet; Horizontal cross bar 4 is passed, and female receptacle 9 is welded on rear cabinet door 5 inboards.
As shown in Figure 2; Rear cabinet door 5 one sides are loaded onto hinge 12, make rear cabinet door 5 switches flexible, and hand lock 8 is installed in the outside of rear cabinet door 5; When car switch 1 is outside test position or cabinet; Horizontal cross bar 4 is in level, and vertically the last wall of inserted link 6 is positioned at the lower-side hole top of cabinet channel-section steel 10, the downside of female receptacle 9, but rear cabinet door 5 free switchs; When car switch 1 by test position when move in the service position; Creep along the inclined-plane of horizontal cross bar 4 in car switch 1 left side side guide wheel 2 down; Horizontal cross bar 4 is that rotate at the center with the axle of bearing 3, promotes vertical inserted link 6 and moves upward, and makes the upper-side hole of its hole of passing female receptacle 9 successively and cabinet channel-section steel 10; After car switch 1 moved to the service position, vertically inserted link 6 firmly pinned 9 with female receptacle 9, can't rear cabinet door 5 be opened, and reaches the purpose that prevents mistakenly entering charged chamber.
