Description
[technical field]
The utility model belongs to high-voltage electrical equipment technical field, relates to a kind of leading screw for high-tension switch cabinet and advances lower floor's car device.
[background technology]
The mode that the many employings of current domestic high-tension switch cabinet lower floor car advance manually; And the JYN1-12 contact box of supporting fixed contact and contact box integral type, electric conductor exposes, and again without position instruction, operating personnel are as easy as rolling off a log touches high-voltage charged body, abnormally dangerous.And the valve plate of JYN1-12 contact box controls by spring, folding is very dumb, handcart by manual feed process due to firmly uneven, JYN1-12 contact box valve plate be easily damaged or valve plate stuck, cause lower floor's car to push away to enter problems such as also can not pull.
[utility model content]
The purpose of this utility model is to provide a kind of leading screw for high-tension switch cabinet to advance lower floor's car device.
For achieving the above object, the utility model is achieved by the following technical solutions:
Leading screw for high-tension switch cabinet advances lower floor's car device, comprises lower floor's frame and is arranged on the disjunctor insulator on framework, disjunctor insulator is connected with contact arm, contact arm is fixed with contact; Lightning arrester or voltage transformer are installed on chassis base, and lightning arrester or voltage transformer are connected with contact arm by connecting copper bar; The chassis vehicle adopting leading screw propulsive mechanism is provided with below framework.
The utility model further improves and is:
The below of contact is provided with the push pedal for opening valve.
Push pedal is arranged on framework, and when handcart advances, push pedal pull switch cabinet lower floor valve mechanism, opens the valve plate on cabinet, and when lower floor's car arrives service position, galvanic circle is connected.
Contact is Mume flower contact, and by bundle spring clamping.
Framework is to be assembled after welding, spraying after adopting steel plate bending.
Disjunctor insulator utilizes bolt together with framework bolt, is used for supporting contact arm and other electric conductors.
Contact arm and disjunctor insulator utilize the inserts on disjunctor insulator to fix.
Chassis vehicle adopts circuit breaker universal chassis car, with the framework of lower floor car by screw thread bolt, drives lower floor's car motion.
Lightning arrester is also connected with lightning arrester with the use of discharge counter.
Compared with prior art, the utility model has following beneficial effect:
The utility model utilizes the framework feature of existing lower floor car, changes chassis vehicle into leading screw advance by manual feed.Make the motion of lower floor car more steady, and provide lower floor's turner work, test position contact and locking position for user, avoid the lower floor's valve breaking switch cubicle when lower floor's car passes in and out switch cubicle, greatly reduce after-sale service workload.Except the fallible components such as replacing fuse, upper deck switch cubicle is almost accomplished non-maintaining.The feature of the utility model patent is also that structure is simple, by means of only changing little part, just can reach requirement.Cost increases few than proterotype lower floor car, and the switch cubicle after-sale service amount of subzonal layer car is greatly reduced, and runs safety and reliability, has greatly saved production cost, improve product reliability.After adopting the switch cubicle of this patent form to put into operation, customer complaint and after sale workload are almost nil.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure, 1 is framework; 2 is disjunctor insulator; 3 is contact arm; 4 is Mume flower contact; 5 for connecting copper bar; 6 is lightning arrester; 7 is push pedal; 8 is chassis vehicle; 9 is discharge counter.
[embodiment]
Below in conjunction with drawings and Examples, the utility model is described in detail.
See Fig. 1, the utility model comprises lower floor's frame 1, the disjunctor insulator 2 be arranged on framework 1, to be connected with disjunctor insulator as conductor contact arm 3, the Mume flower contact 4 be fixed on contact arm, be connected copper bar 5, lightning arrester 6, for opening the push pedal 7 of valve, being with the chassis vehicle 8 etc. of leading screw propulsive mechanism.Wherein, the threaded insert that framework and disjunctor insulator, disjunctor insulator and contact arm are carried by disjunctor insulator two couples together.Mume flower contact is arranged on contact arm, by bundle spring clamping.Lightning arrester is arranged on chassis base, also can install on framework as required discharge counter (now only need on framework fitting insulating panels, lightning arrester is arranged on insulation board).Connect by being connected copper bar 5 between lightning arrester with contact arm.Thus formation galvanic circle.
As shown in Figure 1, when lower floor's car will move to service position from the test position of switch cubicle, as long as crank is inserted in chassis vehicle crank way, rotate crank gently, drive screw turns, the roller of the push pedal pull switch being now fixed on lower floor's frame both sides cashier's office in a shop lower floor's valve mechanism, opens lower floor's car valve fast.When lower floor's car arrives service position, lower floor's lock fixes on service position, and the service position indicator light on switch cubicle instrument door is bright, and lower floor's car secondary plug is locked on switch cubicle, not hot-pluggable, operates very safe and reliable.
Leading screw described in the utility model is adopted to advance lower floor's car can reach the requirement of shelter of switch cubicle.Can prevent operating personnel and electrified body from entering in switch cubicle, meet the degree of protection requirement of IP2X between switch cubicle compartment, shell IP4X.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of this specification, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the utility model protection.
