With reference to Fig. 7 and Fig. 8, operating mechanism includes frame, hard interlock assembly, stored energy operation bar 41, breaking-closing operating bar 42 With spacing lug 43, stored energy operation bar 41 and breaking-closing operating bar 42 are rotationally erected on frame, and spacing lug 43 is outwardly Ground extends and horizontally arranges, spacing lug 43 is arranged between 454 division and combination brake-operating rod(lever) 454 of stored energy operation bar.

Hard interlock assembly includes cam 48, pushing block 47, jam plate 44 and elastic component 46, and cam 48 is arranged on breaking-closing operating bar 42 middle part, cam 48 are rotated with the rotation of breaking-closing operating bar 42, and cam 48 is provided with pin hole.

Jam plate 44 can be vertically slidably arranged on frame, and jam plate 44 is included towards outer end face and bottom plate 451, under With being in horizontally disposed towards outer end face, bottom plate 451, sliding slot vertically is being provided with towards outer end face on vertically for end plate 451 452, screw 453 is fixed on frame through sliding slot 452, and the operation lever 454 to extend outwardly is arranged on towards on outer end face, operation lever 454 pass through the hole 25 of operation panel 2, and jam plate 44 sets at least two lock pillars 45 in bottom plate 451, and lock pillar 45 is used for and cable vault The lockhole of door-plate coordinates, and elastic component 46 is connected between bottom plate 451 and frame, and specifically, lock pillar 45 passes through 451 ground of bottom plate Set, elastic component 46 is spring, and spring pocket is outer in lock pillar 45 and is abutted with bottom plate 451.

Frame is provided through ground limiting slot, and pushing block 47 passes through limiting slot, and upper end 471 and bottom 472 are located at respectively The both ends of limiting slot, pushing block 47 can be arranged on frame with radially sliding along breaking-closing operating bar 42, you can in the horizontal direction Slip also can be slided vertically.The upper end 471 of pushing block 47 is provided with sliding slot, and sliding slot is vertically extension and upper end The sliding slot of open lower end closing, pin 49 pass through pin hole and sliding slot, and the bottom 472 of pushing block 47 can be connected with bottom plate 451.

Therefore by the setting of hard interlock assembly, when breaking-closing operating bar is rotated and closed a floodgate, turn with moving cam It is dynamic so that pushing block pushes lock pillar downward, then realizes that the physics of cable vault's door-plate locks firmly, and under gate-dividing state, pushing block with Bottom plate separates, and the physics that cable vault's door-plate is also that by under the set pressure of elastic component locks firmly, and at this time Operation lever can be operated lock pillar is up lifted and unlocked, under "on" position, the effect based on pushing block, operation lever is to grasp Make what is used, therefore can realize the protection to cable vault's door-plate well, improve barrier propterty.

Simultaneously as need to prevent the main of illegal operation from including stored energy operation bar and breaking-closing operating bar, therefore it is main right It is protected, and is by setting spacing lug first, is not only enabled operation panel accurate contraposition, also enables handle hole Enough it is respectively aligned to two operation levers, while also so that the first cover board covers alignment positioning, and the positioning is semienclosed, therefore energy Enough prevent the invasion and interference in the external world.In contrast, the protection priority level of breaking-closing operating bar is higher than stored energy operation bar, therefore right The protection of stored energy operation bar is to use the rotating cover board of horizontal direction so that after opening will not be on automatic cover, convenient operation, and For breaking-closing operating bar, since the second cover board is vertically rotated along operation panel, therefore after end of operation, in gravity Under drop, then automatically reset, effectively improve the degree of protection of operation panel, while using pellucidly setting, can be more Intuitively operated, and do not influence overall aesthetic degree.

And when operation panel is aligned and installed, it is convenient using the setting of eaves portion, cramp and via, contraposition, fasten positioning side Just, lower end is also to be fixed using eaves portion so that the installation of whole operation panel is more convenient.

And the setting by common bottom seat, the transverse slat and the side plate at both ends put in mainly utilizing, are determining that switch is single After the quantity of member, using the cable vault of baffle interval respective numbers, due to being to be used to install high-voltage circuitbreaker above cable vault Closed gas tank, therefore easily heavier high-voltage circuitbreaker can be sling using lifting equipment, then be separately mounted to each electricity The top of cable room, meanwhile, pressure relief opening and isolation board are additionally provided with, when explosion time occurs for cable vault, blast pressure can be from pressure relief opening Discharge, prevents from producing from front side so as to protect user, and sets corresponding clamping-line structure in bottom, facilitates construction personnel Arrange circuit.

Then, common case linear quadratic control room is installed, since control circuit, monitoring circuit are various, especially opened more Under the application scenarios for closing unit, the indoor wiring of case linear quadratic control is especially complicated altogether, therefore this case uses the arrangement of penetration type, solves Connectivity problem between single switch element in the prior art, all control circuits, monitoring circuit in ring main unit are being passed through Arrangement in the cavity worn, not only facilitates installation and is also convenient for debugging.
