Description
Technical field
The utility model relates to the switchgear of alternating current.The moveable high-voltage switchgear that novel interlock is arranged that particularly suitable substation (station) power transmission and distribution are used.
Background technology
At present, high-tension switch cabinet, be built-in with bus-bar room, the little bus-bar room of secondary, control room, breaker chamber, cable vault by its functional character at cabinet, but its cabinet is the framework external application steel plate that adopts the angle steel welding, and the distortion during owing to welding and processing and manufacturing often makes the geometry of cabinet, size not guarantee, not only influence assembly quality, and profile is attractive in appearance inadequately, although by plastic-blasting, but still lacks aesthetic feeling.In addition, on fool proof interlock, also perfect not to the utmost, when circuit breaker cart is in the service position, breaker closing, on the control lever shaft that operating lever can be inserted into ground connection opening is connected, just handcart has blocked the connecting lever rotation that is connected on the earthed switch operating axis, and the earthed switch that can not close, obvious this interlock, when misoperation, to bear sizable power, not only be awkward maintenance, and be easy to cause device to damage.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of volume little, and aesthetic in appearance, interlock is safe and reliable, a kind of easily moveable high-voltage switchgear that novel interlock is arranged of operating maintenance.
The purpose of this utility model realizes with following technical scheme: the moveable high-voltage switchgear that novel interlock is arranged, the difference of itself and prior art is: a cabinet with the plate type part assembling is arranged, be divided into bus-bar room in the cabinet internal upper part with midfeather, breaker chamber, on midfeather, be fixed with the static socket that joins with bus, the circuit breaker cart that connects circuit breaker is housed in the breaker chamber, moving contact on the circuit breaker matches with the static socket that bus joins, the sealing of breaker chamber top is equipped with the control room, and cabinet top, top, control room is provided with the little bus-bar room of secondary; The bottom rear side is the cable vault in the cabinet, the indoor control lever shaft interlock that joins with the earthed switch connecting lever that is equipped with.Described cabinet with the plate type part assembling, or the steel plate that adopts high-quality is through numerical control is cut, dashed, the bender bed is processed into plate type part, behind plastic-blasting, assemble with counter-sunk screw, or adopting the aluminizing zine plate to be processed into plate type part through numerical control device assembles; So just stopped welding deformation, and guaranteed the shape and structure and the size of cabinet especially cabinet angle rib to be shown, profile is especially attractive in appearance, and for further increasing the decorative aesthetics of cabinet, in the periphery of cabinet door face board face, symmetry is pasted with moulding.The described control lever shaft interlock that joins with the earthed switch connecting lever that in the cable vault, is equipped with, it by baffle plate, operate macro-axis, be loaded on lock dog on the macro-axis back segment, emergency release screw, push and block cover, connecting lever cover, spring, the pull bar that joins with the earthed switch connecting lever is housed at the macro-axis middle part, and the locking mechanism that on the macro-axis leading portion, joins, and forms with the action bars of shaft rear end inserting greatly; The front and back ends of manipulation macro-axis is connected to the front and back ends on the cabinet side plate inwall respectively, and parallel with cabinet side plate inwall; On the cabinet doorframe of push and block cover below, baffle plate is housed; Being loaded on snap close panel seat, the operated clamp that the locking mechanism on the macro-axis leading portion joins by lock shaft, torsion spring, limiting plate, lock connecting lever, with the lock connecting lever forms.When handcart is in the service position, breaker closing, the earthed switch separating brake, the back door is closed, and operated clamp can not lift, and operated clamp has blocked the manipulation macro-axis, and action bars can not be inserted; Work as breaker open operation, and when retreating to test position, when earthed switch closed a floodgate, operated clamp lifted, action bars can insert, open the back door, and guarantee the safety of operation, the operated clamp in the device lifts, only move downward and just can finish with the strength of finger, on the shaft rear end face of this external macro-axis, the emergency release screw is housed, can be in case of emergency, the back door is opened, keep in repair, and needn't damage the interlocking piece installing, just can take off the back door, therefore, operating maintenance is very convenient, thereby realizes control lever shaft interlock operation of the present utility model, maintenance, convenient, safe and reliable purpose.
Compared with prior art, the utility model not only volume is little, good looking appearance, and also its control lever shaft interlock operating maintenance is convenient, safe and reliable.
