Description
Technical field
The present invention relates to a kind of three-phase ganged actuating device and high-voltage switch gear that high-voltage switch gear uses.
Background technology
Three-phase high-voltage switchgear includes threephase switch, realizes the same of switch motion by kinematic link between threephase switch
Step property, specially kinematic link rotate under drive shaft drives, and the connecting lever of threephase switch is all hinged on kinematic link, and transmission is even
Three connecting levers are driven to be synchronized with the movement during bar motion.In high-tension switch gear transport and installation process, if kinematic link is one
Entirety, as depicted in figs. 1 and 2, due to connecting rod, be connected phase with connecting lever unadjustable to position, the manufacturing and fixing error of connecting rod
It can be caused with connecting lever to be connected difficulty, thus higher to switch parts machining required precision, again because kinematic link can not be split,
If being assembled into a transport with kinematic link after switchgear is connected, then can increase transport difficulty and in-site installation difficulty；If
Kinematic link is made two connecting rods be hinged mode, as shown in Figure 3 and Figure 4, although the single-phase of switchgear can be realized
Switch individually transport, ressembles behind scene again, but due to two connecting rods and the junction point of three connecting levers relative position also
Cannot regulate, as the manufacturing and fixing error of connecting rod causes it to be connected difficulty with connecting lever when installing at the scene, it addition, two
Root connecting rod is that mutual overlapping mode connects, and is between two connecting rods at middle connecting lever, and the axis of two connecting rods is not one
On bar straight line so that the space shared by connecting rod entirety is relatively big, more can the company of causing in the case of the installation site of connecting rod is smaller
The degree of difficulty that bar is installed, it addition, because two connecting rods are by during link bolt transmission power, two connecting rods the most coaxially cause power
Arm is bigger so that the twisting resistance suffered by link bolt is relatively big, unfavorable to the service life of link bolt.
Apply for that the Chinese patent that notification number is CN104979127A discloses the three-phase ganged transmission dress of a kind of high-voltage switch gear
Put, including first connecting rod assembly and second connecting rod assembly, two link assemblies are equipped with threaded adjusting structure to regulate connection rod set
The length of part, two link assembly two ends are equipped with joint, and two link assemblies are mutually overlapped by respective joint, and by hinged
Bolted splice, joint is provided with and three hinged required hinge holes of connecting lever, and the connecting lever being wherein in centre is positioned at two connection rod set
In the middle of the joint that part mutually overlaps, the joint that i.e. two link assemblies mutually overlap lays respectively at centre in the radial direction at connecting rod
The both sides of connecting lever, and being connected by link bolt, after connecting lever is connected with connecting rod, three connecting levers are positioned at the pin joint of connecting rod
On same straight line.
This actuating device solves the uncontrollable problem in relative position between kinematic link and the pin joint of connecting lever, and makes
Convenient transportation, cost-effective, but there is also following shortcoming: during two connection rod set overlap joints, lay respectively at the both sides of middle connecting lever,
Make two connecting rods not coaxial, cause kinematic link entirety to be taken up space relatively big, make when connecting lever and single-phase switch are close together
Become kinematic link installation difficulty；It addition, two connecting rods coaxially also can not increase between two connecting rods in link bolt power transmittance process
The arm of force, cause the twisting resistance suffered by link bolt relatively big, thus reduce the service life of link bolt.
Summary of the invention
It is an object of the invention to provide a kind of three-phase ganged actuating device, to solve between connecting rod the most point-blank
And cause kinematic link to take up space relatively big and link bolt by the bigger technical problem of twisting resistance.
