The utility model belongs to the field of distribution substation protection. A 10kV inlet wire protection monitoring device comprises voltage transformers and breakers, 1# inlet wire terminal connecting a breaker a is connected with bus I in series, 2# inlet wire terminal connecting a break b is connected with bus II in series, the bus I and the bus II are connected in series, the bus I and the bus II are connected in sequence with the voltage transformer a and the voltage transformer b, current transformers are all provided with digital media receivers, a voltage transformer c is connected between the 1# inlet wire terminal and the breaker a, a voltage transformer d is connected between the 2# inlet wire terminal and the breaker b, and a breaker c is arranged between the bus I and the bus II. The beneficial effects of the 10 kV inlet wire protection monitoring device are that protection functions are provided to inlet wire power source, and the protection functions comprise current quick-break protection, current protection for low voltage starting, acceleration protection, no-voltage protection, bus linkage protection, bus latching out, control circuit break abnormity alarming function and the like; and when faults are generated to hardware of the protection device, self-detection is carried out to the faults of the device, and the faults comprise fixed value self-check error, relay latching out badly, AD self-check errors and the like, so that energy and time of repairing personnel are saved when the faults are generated.

Description

10kV incoming relay-protection supervising device
Technical field
The utility model belongs to the power distribution protection field, is specially a kind of 10kV incoming relay-protection supervising device.
Background technology
Development along with society; the use of power distribution cabinet is more and more; the technical merit of distribution substation's secondary device has had very big progress in recent years; achievement is obvious to all; there are a lot of problems but in the running of reality, throw away; for example design is complicated; need spend great amount of manpower during maintenance and material resources are carried out fault detect; so just can keep in repair; will spend a large amount of time equally during maintenance, waste a large amount of time and efforts, this phenomenon has illustrated; it is not yet in place that China's prior art is done at aspects such as unit protection and fault self-checkings, can not well use for people.
Summary of the invention
At the problems referred to above, the utility model provides a kind of 10kV incoming relay-protection supervising device, not only can finish incoming power protection, control integrated function, and perfect in shape and function, compact conformation is small and exquisite, has higher reliability.
The useful novel 10kV incoming relay-protection supervising device of this reality; be to be constituted by voltage transformer and circuit breaker; the 1# end of incoming cables connects circuit breaker a and connects with the bus I; the 2# end of incoming cables connects circuit breaker b and connects with the bus II; the bus I is connected with the bus II, and the bus I has been connected voltage transformer a and voltage transformer b respectively with the bus II.
As further improvement of the utility model, be connected to voltage transformer c between 1# end of incoming cables and circuit breaker a.
As further improvement of the utility model, be connected to voltage transformer d between 2# end of incoming cables and circuit breaker b.
As further improvement of the utility model, voltage transformer a, voltage transformer b, voltage transformer c and voltage transformer d all are connected with digital media receiver.
As further improvement of the utility model, be provided with circuit breaker c between bus I and bus II.
The beneficial effect of 10kV incoming relay-protection supervising device of the present utility model is; to current protection, acceleration protection, o-volt protection, bus interlock protection, bus locking that incoming power has current quick, a low voltage starting leave, defencive function such as control loop broken string abnormality alarming; in the time of also can breaking down at the hardware of protective device; fault to device is carried out self check; comprise faults such as the definite value self check makes mistakes, when breaking down, saved maintenance personal's energy and time.
Description of drawings
Fig. 1 is 10kV incoming relay-protection supervising device schematic diagram.
Embodiment
10kV incoming relay-protection supervising device of the present utility model as shown in Figure 1; be to be constituted by voltage transformer and circuit breaker; 1# end of incoming cables 1 connects circuit breaker a2 and connects with bus I 3; 2# end of incoming cables 4 connects circuit breaker b5 and connects with bus II 6; bus I 3 is connected with bus II 6, and bus I 3 has been connected voltage transformer a7 and voltage transformer b8 respectively with bus II 6.Be provided with circuit breaker c12 in bus I 1 and 6 of bus II.
Wherein, between 1# end of incoming cables 1 and circuit breaker a2, be connected to voltage transformer c10; Be connected to voltage transformer d11 between 2# end of incoming cables 4 and circuit breaker b5.Described voltage transformer a7, voltage transformer b8, voltage transformer c10 and voltage transformer d11 all are connected with digital media receiver 9.
10kV incoming relay-protection supervising device of the present utility model is hauled oneself willingly into pattern and is applicable to single busbar connection or sectionalized single busbar connection.During normal the operation, block switch is at closing position, and two inlet wires one main are equipped with.If it is zero that 1# inlet wire decompression, the digital media receiver of circuit breaker a detect voltage transformer a voltage, and no current, circuit breaker a is closing the position, and circuit breaker b is in a minute position, and the prepared auto restart protection drops into, and voltage transformer d has voltage, then starts the prepared auto restart action.Jump this side service entrance switch earlier, after tripping operation is finished, close the offside service entrance switch by circuit breaker c, the prepared auto restart action is finished.The prepared auto restart process of 2# inlet wire decompression is identical therewith.
