Description
Technical field
This utility model belongs to 10KV permanent-magnetic switching divide-shut brake control loop technical fields, more particularly to one kind PLC realities
Existing permanent-magnetic switching intelligent controller.
Background technology
At present the 10KV circuits of many 66KV transformer stations use substantial amounts of permanent magnetic mechanism switch【Permanent magnetism keeps, Electronic Control
Electromagnetic operating mechanism】, the permanent magnetic mechanism switch has frame for movement simple, is hardly damaged, durable in use, low driving power etc.
Advantage.But it is its shortcoming that its closing loop shares a coil, the relay protection dress being connected with switch closing loop
Put needs output tripping operation and order of closing a floodgate, it is impossible to which breaker tripping and closing order is directly directly connected to a line of permanent magnetic mechanism switch
On circle, and breaker tripping and closing order can only the short stay on tripping coil, these features must use an intelligent controller
The connection to protection device and switching mechanism coil is realized, when original intelligent controller is damaged, switching just cannot be carried out point
Closing operation, a kind of programming is carried out to realize that the breaker tripping and closing between switching and protecting are returned using PLC
The connection on road, realizing the divide-shut brake of switch needs.
This utility model permanent-magnetic switching intelligent controller technical issues that need to address are.
1st, breaker tripping and closing pulse output time it is unsuitable it is oversize also should not be too short, automatically terminate after breaker tripping and closing task is completed.
2nd, the automatic switchover for completing breaker tripping and closing order is automatically controlled by secondary circuit.
3rd, cancel the charge circuit of combined floodgate electric capacity, change the switching to closing circuit by PLC realization, and set
Count into rational combined floodgate order output time.

Close opening into auxiliary signal in open position+operating position or+testing position.
2）As long as the function of controller.
Make to export to the breaker tripping and closing order of permanent-magnetic switching, cut off immediately after breaker tripping and closing task is completed.
Breaker tripping and closing order switchs coil and can not obtain reverse electromagnetic signal after withdrawing, and makes switch rebound.
3）Permanent-magnetic switching only one of which coil, obtains being closed a floodgate when left terminal positive electricity, the order of right terminal negative electricity；Obtain
Separating brake is carried out when right terminal positive electricity, the order of left terminal negative electricity.
4）After permanent-magnetic switching obtains breaker tripping and closing order, switch could not complete breaker tripping and closing task, and breaker tripping and closing pulse should be certainly
Disorder of internal organs breaks.
5）Breaker tripping and closing order should be exported by the contact of Large Copacity auxiliary reclay.
