Abstract

The utility model relates to a mechanical interlocking of an electric control cabinet, in particular to a program manual control single-disk mechanical interlocking device used for the electric control cabinet. The utility model consists of a casting manipulator and a program manual control single-disk mechanical interlocking mechanism on the casting manipulator. With the utility model, the problem that integration of the mechanical interlocking and the electric control cabinet is lacked currently is solved, and thereby the operation security of the electric control cabinet is improved.

Description

A kind of electrical control cabinet manual single-deck mechanical interlocks of program

Technical field

The utility model relates to the electrical control cabinet mechanical interlocking, particularly relates to a kind of electrical control cabinet manual single-deck mechanical interlocks of program.

Background technology

Present high-voltage electrical apparatus control cubicle all is furnished with electrical interlock, with anti-misoperation, and in the power industry practical application, all requirement must be furnished with the mechanical interlocking that can be integrated with existing electrical interlock switch, in the hope of the operation safety and reliability, yet existing mechanical interlocking technology and product can not satisfy above-mentioned requirements, the gate mechanical interlocking is only arranged, and its procedure lock also is independently.

The utility model content

The technical problems to be solved in the utility model is at the above-mentioned problems in the prior art, and a kind of electrical control cabinet manual single-deck mechanical interlocks of program that can move with the safety operation that electrical interlock in the existing electrical control cabinet is connected as a single entity is provided.

The technical solution of the utility model is made up of support and the mechanical interlock mechanism on it, it is characterized in that: its support is the foundry goods support, and the position that hand behaviour single-deck is installed is arranged above, and guiding installing hole, bearing and the base plate thereof of each link rod of mechanical interlock mechanism is installed; Its mechanical interlock mechanism is an electrical control cabinet with the manual single-deck mechanical interlock mechanism of program, comprises the hand behaviour's single-deck that is installed in above-mentioned position and the link mechanism of locking bolt link mechanism, electric isolating switch, vacuum circuit-breaker, regulator cubicle door and auxiliary switch thereof.

Described hand behaviour single-deck can connect the link mechanism of electric isolating switch in the electrical control cabinet, vacuum circuit-breaker, auxiliary switch and cabinet door lock bolt by manual operation, and executive program closes the position or divides the position.

The beneficial effects of the utility model are to have solved the problem that electrical interlock is integrated in suitable mechanical interlocking of present nothing and the existing electrical control cabinet, have guaranteed the operation of electrical control cabinet correct.

Embodiment

With reference to accompanying drawing 2-Fig. 6 as can be known the utility model form by support and the mechanical interlock mechanism on it, it is characterized in that: its support is on-deformable single-casting support 1; Its mechanical interlock mechanism is the electrical control cabinet manual single-deck mechanical interlock mechanism of program, comprises being installed in 1 liang on support The hand behaviour's single-deck 9 on the shape batten 31 and 32 in the through hole 36 and 37 and the link mechanism of lock pin 15 thereof and vacuum circuit-breaker locking bolt 14 link mechanisms that discharge locking mechanism and should coil.

Support 1 middle part has two

Hand behaviour single-deck 9 installation positions 33 and axle 2 that shape lath 31 and 32 constitutes are installed through hole 36 and 37, the bottom has two concentric onesize link rod 16 guiding that through hole 54 is installed, its support lower right side has pole 48, top has lock pin 15 guiding that through hole 35 is installed, the bottom has the link rod the same with hole 54 16 guiding that through holes 34 are installed, there is base plate 7 on the right side, there is trivial 3 connection holes 49 the plate bottom and puts plate 4 connection bearings 40, the base plate middle part has keeper 5 bearings 18, top that reset tension spring 12 hook bars 13 are arranged, and frame has an installing hole 45 (Fig. 5, Fig. 6 and Fig. 7) for four jiaos.

There is the through hole 50 of installation at hand behaviour single-deck 9 (Fig. 2, Fig. 8, Fig. 9) center, and the link rod 19 and hand-operating lever (user the provides for oneself) jack 51 of electric isolating switch link mechanism (Fig. 2) arranged on the peripheral surface of dish, and lockhole is not shown in the dish, because of deciding on user's need its position.

Centre bore 50 is used for fixing its dish installation shaft 2, is installed in through hole 36 and 37 and rotatable (Fig. 2) by this axle.

Hand behaviour single-deck 9 withdraws from the dish behind the lockhole at lock pin 15, dish is in separates the pin free state, under artificial the promotion, upwards rotate, link rod 19 rotates, and drives electric isolating switch combined floodgate in the electrical control cabinet, vacuum circuit-breaker adhesive, connects circuit, forces its link mechanism locking bolt 14 to insert its dish lockhole, locking disk, drive cabinet couplet on the door lever lock door, drive auxiliary switch link rod (not shown) and close the position, finish an integrated electrical control operation of program electromechanical interlock (Fig. 1) at this point.

The link mechanism of hand behaviour single-deck 9 lock pins 15 comprises by the plate 6 parallel fork-shaped locking bolt lock pins 15 that connect into and link rod 16, support 48, guiding installation through hole 35,34 and 54, the pendulum plate 4 that connects link rod 16 right-hand members, pendulum plate 4 positioning supports 40 and 18, the raised pin 23 of keeper 5 and the spherical handgrip 10 of pendulum plate 4 upper ends.

The release locking mechanism of lock pin 15 locking bar mechanisms, by dowel fixes at the lock dog 52 on link rod 16 right sides, be connected in the reset tension spring 21 that lock frame 3 on the base plate 7 and an end contiguous block 52 other ends are negative 7 by pin 20 and form (Fig. 2, Fig. 3).

Shut when the electrical control cabinet door, locking bolt 5 advances and puts in place; When on the door lock, the moving lock of shipper pole frame 3 moves down and discharges lock dog 52 on the dead bolt 53, and lock pin 15 link mechanisms discharge, and promote spherical handgrip 10 to the right and put in place, and lock pin 15 just withdraws from lockhole, and dish 9 enters operating state (Fig. 2).

Vacuum circuit-breaker locking bolt 14 link mechanisms of hand behaviour single-deck 9, by the hollow bearing 47 in the hold-down support hole 43, the link rod 48 (at plate 7 back sides) and connecting lever 11, the end that are connected on the bearing 47 by pin 54 is its arm front end, and the reset tension spring 12 on the other end tie-rod 13 is formed.

The utility model operation sequence: (operation board denying do not have release and can not operate) again with the cabinet door to the doorstep, after two layers of door and Xiamen are closed tight and locked, moves to right the knop on the panel 10 and puts in place; Action bars is inserted in the operation board jack 51, upwards close a floodgate, at this moment isolating switch is closing position (otherwise for dividing the position); Isolating switch is when closing, and two layers of door in cabinet top and Xiamen are all locked; Leave the pass when minute position, the knop 10 on the panel can move to left and put in place, and at this moment two layers of door in cabinet top and Xiamen have all been separated trivially, allow to open; Circuit breaker is when closing, and no matter operation board 9 is closing the position, dividing position all locked (Figure 11).
