Description
Technical field
This application involves a kind of accumulator group disconnecting link formula fuses.
Background technology
Direct-flow storage battery selects valve controlled sealed lead-acid accumulator in State Grid Corporation of China's uniform requirement substation at this stage,
Its positive and negative the two poles of the earth power supply is connected to straight-flow system busbar by large capacity fuse, to carry out direct-flow storage battery group remodel or
The work of other operations that need to log off accumulator group of person, the large capacity fuse that need to will connect accumulator positive and negative polarities are drawn
It opens, straight-flow system busbar is made to be isolated with direct-flow storage battery group.
But since fuse upper and lower ends are stuck in respective card slot, in order to ensure fuse or more the two poles of the earth and metal card slot
Contact is good, so card slot takes interior pushing-type to design, prevents fuse both ends from loosening, but such design directly contributes fuse very
Difficulty is taken out from card slot, removes fuse and needs to extract using specific purpose tool or hand vice, extracting fuse energetically may cause to melt
Disconnected device support baseboard deformation.Work is finished need to be packed into the fuse removed former card slot, card slot by the operation of accumulator input coefficient
Upper and lower ends are charged, and there are voltage differences for fuse upper and lower ends after checking discharging test, at this time put into fuse
System leads to fuse upper end not if input fuse speed is unjustified compared with upper lower bayonet slot during slow or input fuse
It can be come into full contact with upper end metal card slot, it may appear that sparking phenomenon of arc discharge, and its positive and negative the two poles of the earth fuse standoff distance is close,
Short circuit phenomenon may be will produce, DC charging device and accumulator are burnt, stand in lose direct-current power supply, cause straight in station
Streaming system decompression eventually leads to protective relaying device and breaker control circuit in station and loses power supply, if event occurs for system at this time
Barrier will lead to trip accident of bypassing the immediate leadership, and cause no-voltage of entire station.
Battery fuse used in domestic electrical system puts into and exits and is extremely inconvenient at present, exists and is generating direct current just
The possibility of cathode short circuit, to avoid such accumulator group disconnecting link for happening, facilitating the input of battery fuse and exiting
Formula fuse is with regard to necessary.
Invention content
In order to overcome the deficiencies of existing technologies, present applicant proposes a kind of reduction throwings to move back fuse time, ensures accumulator
Group input or a kind of accumulator group disconnecting link formula fuse for exiting the reliability during straight-flow system.
The application realizes by the following technical solutions：A kind of accumulator group disconnecting link formula fuse includes being arranged in shell
Two contacts that top is connect with accumulator group positive/negative, the rotatable rotating insulated bar of lower part setting in shell, in contact and
It is provided with insulating barrier between rotating insulated bar, insulating frame, insulating frame upper and lower two are provided in the space of insulating barrier both sides
End be respectively fixed with conducting rod, lower conducting rod, lower conducting rod is fixedly connected with rotating insulated bar, and with stretching shell just/
Negative terminal is connected；Conducting rod is connected by an insulating bar on two, and handle is provided in the middle part of insulating bar；It is solid in insulating frame
There are positive/negative fuse, the upper and lower ends of positive/negative fuse to be connect respectively with upper conducting rod, lower conducting rod surely.
Upper conducting rod lower end is provided with upper bed-plate, upper bed-plate lower end be provided with to positive/negative fuse upper end card
The upper connection card slot connect.
Lower conducting rod upper end is provided with lower bottom base, lower bottom base upper end be provided with to positive/negative fuse lower end card
The lower connection card slot connect.
Insulating frame is rotated by shaft of rotating insulated bar.
The insulating frame is channel steel shape comprising one places the cavity of positive/negative fuse.
Through the above technical solution, the application controls the division simultaneously of positive and negative anodes fuse by switch handle, avoids
It is unjustified that upper lower bayonet slot during fuse speed is slower or input coefficient is put into when accumulator group fuse input coefficient, is led
It causes fuse upper end that cannot be come into full contact with upper end metal card slot, sparking phenomenon of arc discharge occurs, improve safety in utilization；This Shen
Fuse division simultaneously is please controlled by switch handle, need not take by hand vice or insurance and pull out tool operation, and operate
Simply, it reduces to throw and moves back fuse time, working efficiency is effectively improved；The application can effectively ensure that accumulator group input exits
Reliability during straight-flow system ensures In situ DC system normal operation, is provided for transformer equipment in station reliable and stable
Power supply reduces the possibility to cause the accident by misoperation, improves economic benefit indirectly.
