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.
