Description
Technical field
The utility model relates to a kind of underlying PT contact connecting structures of high-current switch.
Background technique
With the continuous improvement of China's sustainable development economically and the people's material and cultural life level, user is to electricity
Power demand is increasing, higher and higher to power supply quality and reliability, as electric power enters market as commodity, receives user's
Supervision and selection influence the responsibility for investigating electric power operator on the power failure in power supply, for this purpose, accelerating changing for urban and rural power grids
It makes, the process for accelerating distribution system automation is just particularly important.The AC metal closed switch of heavy current breaker is installed
Equipment, since electric current is larger, it is easy to cause breaker to generate heat, to influence its performance, or even causes accident, therefore need to be in open circuit
Device is additionally arranged at the bottom axial flow blower.When the high current cabinet of the installation axial flow blower need to configure underlying PT hand car again, original lower layer
Space has been unable to meet the installation of former conventional underlying PT hand car, therefore need to reduce to the height of conventional underlying PT hand car, with full
Foot can fill axial flow blower but also load the needs for setting the heavy current breaker cabinet of PT hand car.Some voltage switchgears will in the market
Voltage transformer with fuse is loaded in underlying PT hand car, and is directly contacted with busbar after cabinet, after not being able to satisfy enabling in this way
Degree of protection reaches the requirement of IP2X, runs not safe and reliable enough.
Utility model content
In view of the foregoing drawbacks, easy to operate the purpose of this utility model is to provide a kind of structure is simple, it can either guarantee
Axial flow blower installation can install underlying PT hand car again, meet degree of protection, guarantee that a kind of high current safe and reliable to operation is opened
Close the underlying PT contact connecting structure of cabinet.
Thus the technical scheme adopted by the utility model is
Underlying PT hand car including being placed in bottom in cabinet body is provided with fuse type mutual induction of voltage in underlying PT hand car
Device, band fuse type voltage transformer are equipped with spring contact, and bottom is equipped with the contact matched with spring contact in cabinet body
Box is equipped with the static contact matched with spring contact in the contact box, is equipped with the contact connected with bus above static contact
Busbar, contact busbar are located in contact box and are fixedly connected with contact box, and contact busbar includes L-type plate, and the outer end of L-type plate is equipped with
The touch panel being turned over downwards, touch panel are equipped with guide rail between static contact and spring contact below underlying PT hand car.
As a further improvement of the above technical scheme, the contact box is the box body of inner hollow, and contact box right end is spacious
It opens, the closing of contact box left end, upper end is equipped with through-hole on the left of contact box, and bus perforation through-hole protrudes into contact box.
As a further improvement of the above technical scheme, the side plate of the L-type plate is equipped with connecting hole, the left end of contact box
Inner wall is equipped with mounting hole, and connecting hole is connect by screw with mounting hole.
As a further improvement of the above technical scheme, valve is equipped at the contact box front end, the valve passes through drive
Swing arm is connect with underlying PT hand car.
The utility model has the advantages that:
The utility model structure is simple, easy to operate, by adding a contact busbar in contact box, make its outer end with it is quiet
Contact, it is conductive steady convenient for dynamic and static contact to block original mounting hole on static contact, guarantee safe and reliable to operation.
