The bottom of cable vault 34 is provided with outlet hole 36, and limiting plate 341, two limits are provided on the both sides of outlet hole 36 Sliding slot is formed between the plate 341 of position, ring main unit further includes clamping plate 37, and clamping plate 37 includes 371 He of folder portion for being located at 36 top of outlet hole Cunning portion 372 positioned at 37 both sides of clamping plate, cunning portion 372 are bent from folder portion 371, the extending direction in cunning portion 372 and prolonging for limiting plate 341 Stretch that direction is parallel, cunning portion 372 and the madial wall of limiting plate 341 abut, and limiting plate 341 and cunning portion 372 are penetratingly provided with limit Hole, banking pin then realize the clamping to cable across limit hole by the lap fit of outlet hole 36 and folder portion 371.

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 limit lug 43, stored energy operation bar 41 and breaking-closing operating bar 42 are rotationally erected on frame, and limit lug 43 is outwardly Ground extends and horizontally arranges, limit 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 in 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, jam plate 44 include towards outer end face and bottom plate 451, under For end plate 451 vertically with towards outer end face, bottom plate 451 is in horizontally disposed, and sliding slot is being provided on vertically towards outer end face 452, screw 453 is fixed on across sliding slot 452 on frame, and the setting of the operating lever 454 that extends outwardly is towards on outer end face, operating lever 454 pass through the hole 25 of operation panel 2, jam plate 44 that at least two lock pillars 45 are arranged 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 Setting, elastic component 46 are 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 lower end 472 are located at 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 Sliding 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 closed sliding slot of open lower end, pin 49 pass through pin hole and sliding slot, and the lower end 472 of pushing block 47 can be connect with bottom plate 451.

Therefore turned with moving cam when breaking-closing operating bar is rotated and closed a floodgate by the setting of hard interlock assembly 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 detaches, 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 Operating lever can be operated lock pillar is up lifted and unlocked, under "on" position, the effect based on pushing block, operating lever is can not to grasp What work used, therefore the protection to cable vault's door-plate can be realized well, improve barrier propterty.

Simultaneously as need to prevent the main of illegal operation to include stored energy operation bar and breaking-closing operating bar, therefore it is main right It is protected, and is to limit lug by setting first, is not only enable operation panel accurate contraposition, but also handle hole energy Enough it is respectively aligned to two operating levers, while but also the lid of the first cover board closes alignment positioning, and the positioning is semienclosed, therefore energy Enough prevent extraneous invasion and interference.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 the cover board using horizontal direction rotation so that it will not be conveniently operated on automatic cover after opening, 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 fall, then automatically reset, effectively improve the degree of protection of operation panel, while using being pellucidly arranged, can be more It is intuitively operated, and does not influence overall aesthetic degree.

And when operation panel is aligned and installed, using the setting of eaves portion, cramp and via, contraposition is convenient, fastens 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 total bottom seat, the side plate of the transverse slat and both ends set 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 for installing 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, it is additionally provided with pressure relief opening and isolation board, when explosion time occurs for cable vault, blast pressure can be from pressure relief opening Discharge prevents from being produced from front side so as to protect user, and corresponding clamping-line structure is arranged in bottom, facilitates construction personnel Arrange circuit.

Then, total case linear quadratic control room is installed, since control circuit, monitoring circuit are various, is especially being 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 individual switch unit 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.
