Abstract
The utility model discloses a handcart-type high tension switchgear shutting, including the dolly switch, left side downside guide pulley, intermediate bottom, horizontal pole, a support, vertical inserted bar, a spring, cabinet body channel-section steel, the inserted plate, the back cabinet door, the hand lock, characteristics are that the axle that horizontal pole used on the support rotates as the center, crawl along the inclined plane of horizontal pole one end by left side downside guide pulley, promote the horizontal pole other end, thereby promote vertical inserted bar upwards, pass in proper order on cabinet body channel-section steel, the hole on downside hole and the inserted plate, realize the shutting function, it is convenient to have back cabinet door switch, prevent to miss electrified interval, make the advantage of the simple and convenient safety of operation personnel.
Description
The utility model relates to the locking of a kind of handcart type high-voltage switch cabinet, belongs to field of mechanical technique.
At present; in the 3-10kv distribution system of all kinds of power plants and transformer station; the handcart type high-voltage switch cabinets of using 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; as 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, carry out on the outlet cable end, 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 enters 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 cabinet door upper edge is tilted, and touches the outlet conductor, causes three-phase shortcircuit.
It is convenient that the purpose of this 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 purpose of this utility model realizes as follows.
This locking is made of two parts: transmission mechanism and actuator.
Running part is made of dolly lower-left side guide wheel, the horizontal pavilion of level, bearing, and operating part is made of vertical inserted link, spring, female receptacle, cabinet channel-section steel.
Bearing is fixed on the switch cubicle base plate, horizontal cross bar is fixed on the bearing by the axle on the bearing, can rotate up and down, horizontal cross bar one end is oblique, with advance the car guide wheel and contact, 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, a hole is opened in the central dividing plate bottom of switch cabinet, makes under water that cross bar passes, and female receptacle is fixed on the rear cabinet door inboard, rear cabinet door one side is lived with switch cubicle and is connected, and the hand lock is contained in the rear cabinet door outside.
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.
Below in conjunction with accompanying drawing and enforcement side the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a rear cabinet door structural representation of the present utility model.
As shown in Figure 1, constitute the transmission mechanism of this locking, constitute the actuator of this locking by vertical inserted link (6), female receptacle (9), spring (7), cabinet channel-section steel (10) by dolly lower-left side guide wheel (2), horizontal cross bar (4), bearing (3).
Bearing (3) is welded on the switch cubicle base plate, horizontal cross bar is fixed on the bearing (3) by the axle on the bearing (3), horizontal cross bar (4) can bearing (3) axle be the center, on, the following rotation, horizontal cross bar (4) one ends are made oblique shape, contact with lower-left side guide wheel (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 end pass successively cabinet channel-section steel (10) on, hole on the hole of downside and the female receptacle (9), a hole is opened in the central dividing plate of switch cabinet (11) bottom, and horizontal cross bar (4) is passed, and female receptacle (9) is welded on rear cabinet door (5) inboard.
As shown in Figure 2, rear cabinet door (5) one sides are loaded onto hinge (12), make rear cabinet door (5) switch flexible, and hand lock (8) is installed in the outside of rear cabinet door (5).
When car switch (1) was outside test position or cabinet, horizontal cross bar (4) was in level, and vertically the upper end of inserted link (6) is positioned at the lower-side hole top of cabinet channel-section steel (8), the downside of female receptacle (9), rear cabinet door (5) but free switch; When car switch (1) by test position when move in the service position, the dolly sky closes (1) lower-left side guide wheel (2) creeps along the inclined-plane of horizontal cross bar (4), horizontal cross bar (4) is that rotate at the center with the axle of bearing (3), promote vertical inserted link (6) and move upward, make 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 female receptacle (9) (dotted line state among the figure), rear cabinet door (5) can't be opened, and reaches the purpose that prevents mistakenly entering charged chamber.
