Description
Technical field
It the utility model is related to a kind of Substation Reactive-power Compensation cabinet manually and automatic switching device, more particularly to a kind of power transformation
Reactive compensation cabinet stand manually with self interlocking switching device, belongs to power supply technique field.
Background technology
Reactive power compensation device plays a part of to improve the power factor of power network in power supply system, and it can reduce confession
The loss of piezoelectric transformer and conveying circuit, power supplying efficiency is improved, improve power supply environment.So reactive power compensation device is in electric power
An indispensable very important position is in electric power system.Rational selection compensation device, can accomplish maximum limit
The loss of the reduction power network of degree, improves power grid quality.Conversely, such as selection or improper use, electric power system, voltage may be caused
The factors such as fluctuation, harmonic wave increase.
Due to scene and practical factor require need may at any time manually, automatic switching capacitor, operation find due to equipment
The defects of automatic controller and assembly technology, causes not cutting off and put into automatically electricity when controller interface is located at manual interface
Container, conversely it can not put into and cut off manually capacitor when controller is located at automatic interface.Fig. 1 is seen at controller interface, works as control
When device processed is located at manual interface, KAZ relays obtain electric adhesive, and automatic loop KAZ subsidiary loops close point is opened, and cut off automatic output
Loop；Conversely when controller is located at automatic interface, KAS relays obtain electric adhesive, and KAS pair major loops close point is opened, and cuts off hand
Dynamic loop output loop, may export forward voltage so as to solving controller causes that capacitor can not be cut off manually, so as to solve
Certainly such case causes harm to power system.
In order to solve this problem in time, having must transform existing defect technique.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of Substation Reactive-power Compensation cabinet and thrown manually with self interlocking
Cutting apparatus.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of Substation Reactive-power Compensation cabinet manually with self interlocking switching device, including auxiliary reclay KAZ and it is middle after
Electrical equipment KAS, auxiliary reclay KAZ normally closed auxiliary contact group number are identical with reactive power compensator sales counter number, auxiliary reclay KAS
Normally closed auxiliary contact group number it is identical with reactive power compensator sales counter number；Auxiliary reclay KAZ coil one end, which connects, to be automatically entered
End, its another termination power, its each group normally closed auxiliary contact are connected with input output switching terminal manually；Auxiliary reclay KAS's
Coil one end connects manual input, its another termination power, and its each group normally closed auxiliary contact is with automatically engaging output switching terminal string
Connection.
Auxiliary reclay KAZ normally closed auxiliary contact is three groups, and auxiliary reclay KAS normally closed auxiliary contact is three groups.
Using having technical effect that acquired by above-mentioned technical proposal：The utility model is entered using the auxiliary contact of repeater
The excision in two loops of row and input, automatic, manual loop effectively can strictly be made a distinction, no longer interact.No
The stable operation of power system has only been ensured, while has protected personal safety, and has ensured the utilization rate of equipment.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the circuit theory diagrams of prior art；
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
A kind of Substation Reactive-power Compensation cabinet manually with self interlocking switching device, including auxiliary reclay KAZ and it is middle after
Electrical equipment KAS, auxiliary reclay KAZ normally closed auxiliary contact group number are identical with reactive power compensator sales counter number, auxiliary reclay KAS
Normally closed auxiliary contact group number it is identical with reactive power compensator sales counter number；Auxiliary reclay KAZ coil one end, which connects, to be automatically entered
End, its another termination power, its each group normally closed auxiliary contact are connected with input output switching terminal manually；Auxiliary reclay KAS's
Coil one end connects manual input, its another termination power, and its each group normally closed auxiliary contact is with automatically engaging output switching terminal string
Connection.
Existing three, 35KV Reactive Power Compensation Eqyuipment in Substation cabinet, separately design total capacity 4000kvar, every compensating cabinet peace
It is 1000kvar, 1500kvar, 1500kvar respectively to fill three group capacitor sizes.The present embodiment is to original automatic, manual switching
Loop is in parallel to install auxiliary reclay additional, the auxiliary magnet of auxiliary reclay is serially connected with manually, in automatic loop so that manually and certainly
Dynamic loop forms interlocking.
Automatically enter end COM, i.e. XT1:One direct current auxiliary reclay KAZ coil of access in parallel, the coil other end at 38
Access minus No. 102 lines of power supply.Then tri- groups of normally closed auxiliary contact series connections of KAZ are taken to enter input output switching terminal manually, i.e. SA2:
6、SA3:6、SA4:6 outlets.In SA1:The 10 namely No. 103 same parallel connections of line one direct current auxiliary reclay KAS, Ran Houqu
Tri- groups of normally closed auxiliary contact series connection accesses of KAS automatically engage output switching terminal.
When capacitor automatic/hand switch gets to automatic, direct current auxiliary reclay KAZ coils obtain electric so that are connected on
The normally closed auxiliary contact in manual switching loop is opened, and cuts off the electrical link of manual loop and automatic loop completely, accomplish no matter
Not interfered with behind any interface for controller automatically engages and cut off capacitor.
When capacitor automatic/hand switch gets to manual, direct current auxiliary reclay KAS coils obtain electric so that are connected on
The normally closed auxiliary contact in automatic switching loop is opened, and cuts off the electrical link of manual loop and automatic loop completely, accomplish no matter
Controller does not interfere with input manually and excision capacitor behind any interface.
