Technical field
The utility model relates to the technical field of handcart switch cabinet, and particularly a kind of novel handcart pushing guidance is to system.
Background technology
Switch cubicle mainly is used for the control and protection of electric power system; can be according to the operation of power networks needs with a part of power equipment or circuit input or out of service; but also faulty component is excised fast from electrical network when power equipment or line failure, thereby guarantee the normal operation of fault-free part in electrical network and maintenance of equipment personnel's safety.Because the handcart switch cabinet switch cubicle has good interchangeability, can greatly improve power supply reliability, handcart type commonly used has isolation handcart, metering handcart, circuit breaker cart, capacitor handcart etc., therefore handcart switch cabinet is very important equipment for power transmission and distribution, its safety, reliability service to electric power system safe, effectively move tool and be of great significance.
The handcart track pushes switch cubicle for handcart, is the important composition parts of handcart switch cabinet.Existing handcart track structure generally is provided with the handcart wheel, and without the design of handcart directive wheel, after handcart advanced cabinet, guiding and propelling guiding can only rely on the handcart wheel to realize, handcart advances dumb, and the dynamic/static contact Touch error is larger.After the contact of the moving contact on handcart contact arm fixed contact, when easily causing moving contact interlock fixed contact, bearing up-down force is uneven, so that moving contact distortion or damage.After the energising of primary circuit, easily cause the temperature rise of dynamic/static contact contact point to exceed standard, even cause contact burning.
The utility model content
In view of this, the utility model provides a kind of novel handcart pushing guidance to system, can reduce dynamic/static contact grafting error, improves the handcart propulsive efficiency, thereby guarantees the reliability service of the switch cubicle after the energising of primary circuit.
For solving above technical problem, the technical solution of the utility model is, a kind of novel handcart pushing guidance is to system, described novel handcart pushing guidance comprises handcart guide rail, handcart body to system, be provided with handcart moving contact on described handcart body, after the handcart body pushes handcart guide rail, described handcart moving contact contact handcart fixed contact, the lower end of described handcart body is provided with handcart wheel and handcart directive wheel.
Preferably, described handcart directive wheel is provided with pulley structure, is used for the handcart directive wheel and slides on handcart guide rail.
Preferably, described handcart directive wheel is provided with groove structure, and the cross-sectional view of described groove is circular, is used for the clamping handcart guide rail, the handcart body is fastened on handcart guide rail slides.
Preferably, described handcart wheel cross-sectional view is circular, and its diameter is greater than the diameter of handcart directive wheel cross section circle.
Preferably, described handcart guide rail is two square plates, is fixedly installed between cabinet left plate and cabinet right plate, by handcart track securing member, handcart guide rail is connected with the cabinet right plate with the cabinet left plate respectively.
Preferably, be evenly distributed with handcart directive wheel more than 2 on described handcart guide rail.
Compared with prior art, the utlity model has following advantage:
One, the utility model adopts the handcart directive wheel to be fastened on and slides mode on handcart guide rail, make handcart in progradation, overcome the unbalance stress that only relies on the propelling of handcart wheel and the problem that swings and bounce up and down, make good the contacting of handcart moving contact and fixed contact energy, reduced the dynamic/static contact damage that causes because of the propelling unbalance stress or the temperature rise that causes because of the dynamic/static contact loose contact and exceeded standard.
Two, the utility model is by arranging the handcart directive wheel, realize the handcart directive wheel interlock on the handcart body and be fixed in handcart guide rail in the handcart chamber, under the propelling of handcart advancing mechanism, the handcart directive wheel rolls on handcart guide rail, guiding handcart body direction of propulsion, handcart moving contact can be plugged on fixed contact reliably, safely and smoothly, after handcart closes a floodgate, switch cabinet one-time loop conducting.
Three, this novelly has characteristics such as simple in structure, easy for installation, easy maintenance, can be widely used in handcart guidance system technical field.
