Abstract
A long-service-life switchgear handcart is mainly composed of components of a handcart frame (1), a chassis (2), a contact arm (3), a contact (4), a walking motor (5) and a contact opening-and-closing motor (7). Because no contact tension spring is utilized and the contact is at an open position in moving the handcart, contact resistance increase of the contact caused by wearing aging and tension fatigue of the tension spring is prevented, service life of the handcart contact is prolonged and contact resistance of the contact is reduced. Furthermore cooperation of a handcart walking resistance and a contact friction force in movement of the handcart is prevented so that higher mobility of the handcart is realized. The long-service-life switchgear handcart can be widely applied in high-voltage, medium-voltage and low-voltage armored movable switchgears in power generation, power distribution and power transmission, thereby effectively improving continuity and reliability in power supplying.
Description
Art
The invention belongs to power equipment category, is related to a kind of switch cabinet handcart, long-life switch cabinet handcart is related specifically to.
Background technology
With developing rapidly for process of industrialization, the switch cubicle supporting with it is necessary to have high power supply continuity, to protect
The power supply reliability in card place, current switch cubicle type mainly has armored withdraw type and the fixed two types of armouring.Due to
Failure is inevitable, to take measures on product structure, just in case when breaking down, its function can be keeped in repair by Fast-Maintenance,
Meet the requirement of power supply continuity.The fixed advantage of armouring is that structure is relatively easy, and the probability for breaking down can be low, but its
When having the disadvantage to break down, overhaul very inconvenient, power off time is long.The advantage of armored withdraw type is mounted in the hand of switch cubicle
Energy quick-replaceable on car, thus after breaking down, power off time is shortened dramatically, and has the disadvantage that the abrasion of handcart dynamic/static contact plug connector is big
Aging fast contact resistance increases, and contact failure rate remains high, and seriously constrains the performance of armored withdraw type switch cubicle globality.
Script chassis vehicle is the such as breaker, negative for carrying the higher electric elements of fault rate in drawer-type switch cabinet
Lotus switch, transformer, earthed switch etc., when corresponding electric appliance element breaks down, can be changed at short notice, to shorten
Power off time, raising power supply continuity, but the high fault rate of plug connector, and the position is in the hidden portion of inside switch cabinet
Position, is not easy to operations staff's tour, so that having influence on the service life of switch cubicle integral device.

Specific embodiment
Referring to the drawings 1 and accompanying drawing 2, a kind of long-life switch cabinet handcart of the invention, mainly by cart frame（1）, chassis vehicle
（2）, contact arm（3）, contact（4）And running motor（5）With contact folding motor（7）Composition, cart frame（1）It is installed on chassis
Car（2）Above, contact arm（3）It is fixed on cart frame（1）The back side, contact（4）It is installed on contact arm（3）End, running motor
（5）It is installed on chassis vehicle（2）On, contact folding motor（7）Installed in cart frame（1）Back side contact arm（3）Between；Its feature
It is：The contact arm（3）For the seamless conductor metal pipe of heavy wall, machined making shaping；The contact（4）By multigroup conductor gold
Category contact（11）Composition, per a piece of contact（11）Ancon pass through connecting shaft（13）It is connected to contact arm（3）End, contact（11）
Afterbody by being flexible coupling（12）With contact arm（3）It is electrically connected, contact（11）Bottom Jing be placed in contact arm（3）Internal chain
Plate（6）It is connected to the arm of force（9）, all arm of forces（9）By contact arm（3）Through connecting rod is stretched out at distal opening（10）It is fixed to leading screw（8）
End, leading screw（8）Head end be arranged on cart frame（1）The contact folding motor at the back side（7）Engagement；
The arm of force（9）And connecting rod（10）Material is rigid insulating material；
The contact folding motor（7）For direct current torque motor；
The running motor（5）Two before and after total, using double output shaft multipole brshless DC motor, two ends output shaft directly connects
Connect chassis vehicle left and right sides wheel.
The running motor（5）With folding motor（7）And electrically lock-in control is carried out between major loop, when handcart is in work
Make position running motor（5）After quitting work, folding motor（7）Side can carry out the switching action of contact；Contact（4）It is opened to
