Description
Technical field
The utility model relates to a kind of portable protective relaying device emergency power system, belongs to the emergency protection circuit device for electric that electric power system is special.
Background technology
In recent years, along with the growth of some old electric substation operation time limits, the situation that its secondary device is also faced with close to even having exceeded its cycle of operation its useful life occurs, but because secondary device is made up of a large amount of electronic component, its characteristic determines the impact that device job stability is subject to run the time limit.According to statistics, run the secondary device of 6-10, plug-in unit hardware deficiency frequency obviously rises, comparatively typically installation's power source inversion plug-in unit fault.Inverter, as " heart " of protective device, once break down, will make protective device normally run or directly to stop using, make primary equipment be in the unshielded state of emergency, seriously jeopardize primary equipment and electric power netting safe running.
Because present electric substation is mostly unattended, when protective device breaks down, person on duty can only pass through supervisory control system roughly failure judgement point, accurately cannot navigate to the plate type that device is concrete, can only notify that maintainer processes.After maintainer shows up, find that device inverter fault causes protection out of service, preparation spare part of need turning back.When spare part abundance, this process had both added the time of eliminating defect, increased operation of power networks risk further again; There is no spare part at faulty equipment inverter or stopped production, being then faced with inactive primary equipment, the consequence of transfer load and replacing protection.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and it is reasonable, compact to provide a kind of structure to form, easy to use and reliable, easy to carry, highly versatile, substantially reduce the time because power failure causes protective device out of service, effectively improve the portable protective relaying device emergency power system of power system security and stability; It can serve as temporary source when protective device inverter fault, makes protective device continue to put into operation, solves again the special circumstances such as secondary spare part stopping production, is applicable to multiple producer and uses.
A kind of portable protective relaying device emergency power system, it is primarily of emergency power supply unit body and can form by adapter type power insert, described emergency power supply unit body is built-in with AC/DC, DC/DC binary channels change-over circuit that input voltage can be converted to output voltage, and on emergency power supply unit body, be provided with the power supply indicator, the needle dc voltmeter and can adapter type power insert interface that are communicated with described binary channels change-over circuit;
Described can adapter type power insert comprise an Insertion panel and with can adapter type power insert socket match can adapter type plug head.
As preferably: described can Insertion panel in adapter type power insert and can be detachable syndeton between adapter type plug head, be wherein configured with multiple meet different manufacturers package types can adapter type plug head; Described can adapter type power insert be connected with emergency power supply unit body interface by power bus.
Input voltage described in the utility model is 220V/110V power of alterating and direct current, and output voltage is polytype direct current such as 24V, 15V, and outputted to by power bus can adapter type power insert, for the emergency power supply of protective relaying device; It is reasonable, compact, easy to use and reliable, easy to carry that it has structure composition, and the features such as highly versatile, substantially reduce the time because power failure causes protective device out of service, effectively improve power system security and stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of emergency power supply unit body described in the utility model.
Fig. 2 be described in the utility model can adapter type power insert structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, as shown in Figure 1, 2, a kind of portable protective relaying device emergency power system, it is primarily of emergency power supply unit body 1 and can forming by adapter type power insert 2 of matching, described emergency power supply unit body 1 is built-in with AC/DC, DC/DC binary channels change-over circuit that input voltage can be converted to output voltage, and on emergency power supply unit body, be provided with the power supply indicator 11, the needle dc voltmeter 12 and can adapter type power insert interface 13 that are communicated with described binary channels change-over circuit;
Described can adapter type power insert 2 comprise an Insertion panel 21 and with can adapter type power insert socket match can adapter type plug head 22.
Shown in figure, described can Insertion panel 21 in adapter type power insert 2 and can be detachable syndeton between adapter type plug head 22, be wherein configured with multiple meet different manufacturers package types can adapter type plug head 22; Described can adapter type power insert 2 be connected with emergency power supply unit body 1 interface by power bus.
Embodiment: emergency power supply unit body 1 includes power supply indicator 11, needle dc voltmeter 12 and can adapter type power insert interface 13.Device has AC/DC, DC/DC binary channels translation function, can be that to be converted to output voltage be polytype direct current such as 24V, 15V to 220V/110V power of alterating and direct current by input voltage.
Fig. 2 is can adapter type power insert, and it is by Insertion panel 21 and can form by adapter type plug head 22.Can adapter type plug head 22 be design for disassembly, can according to the different configuration separately of each producer's protective device power panel model.
Can be connected with emergency power supply unit body 11 interface by power bus by adapter type power insert 2.
