Abstract
The utility model belongs to the technical field of detectors, and discloses a bolt tightness detecting system for storage batteries of a transformer substation. The bolt tightness detecting system is mainly technically characterized by comprising a storage battery, the storage battery is provided with a connecting bolt with a fastening nut, and a piezoelectric sensor is disposed under the fastening nut on the connecting bolt and connected with a direct-current screen monitor via a signal line. During usage of the bolt tightness detecting system for the storage battery of the transformer substation, the piezoelectric sensor is mounted under the fastening nut on the connecting bolt, and an alarming value of the direct-current screen monitor is set. The piezoelectric sensor can monitor the fastening condition of the connecting bolt in real time, and further can output a linear curve for displaying the tightness of the connecting bolt. When the connecting bolt looses to the range of the alarming value, the piezoelectric sensor transmits alarming signals to the direct-current screen monitor, and the direct-current screen monitor can display looseness of the specific connecting bolt on the anode or cathode of the storage battery so as to remind operation staff and repair staff.
Description
Technical field
The utility model belongs to the appliance technical field, relates in particular to a kind of transformer station accumulator bolted degree detection system.
Background technology
Battery pack is the very important secondary device of transformer station, and the quality of its performance and quality is directly connected to the stable operation and the device security of electrical network.In recent years, cause the accident of protective device dead electricity to occur repeatedly because the battery pack coupling bolt is loosening after charging set is stopped transport.Because fastening dynamics was not enough when the part accumulator was installed, the pole corrosion causes loose contact in the operational process, and accumulator housing changes the bolt elasticity is changed behind the long-play.Bolt looseness possibly cause the battery pack open circuit, can make protective device lose direct supply under the accident conditions.
The utility model content
The technical matters that the utility model solves just provides a kind of transformer station's accumulator bolted degree detection system that can monitor the fastening situation of coupling bolt at any time.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise accumulator; Accumulator is provided with the coupling bolt that has clamp nut; On the described coupling bolt clamp nut below be provided with piezoelectric sensor, piezoelectric sensor is connected with the direct current cabinet supervising device through signal wire.
Transformer station's accumulator bolted degree detection system that the utility model provided is provided with piezoelectric sensor below the clamp nut on each accumulator coupling bolt, piezoelectric sensor is connected with the direct current cabinet supervising device through signal wire.During use, with piezoelectric sensor be installed in clamp nut on the coupling bolt below, and the direct current cabinet supervising device set alarming value.Piezoelectric sensor can be monitored the fastening situation of coupling bolt in real time, can also export to show coupling bolt tautness linearity curve.When coupling bolt became flexible to the alarming value scope, piezoelectric sensor sent alerting signal to the direct current cabinet supervising device, and the direct current cabinet supervising device can show that concrete which battery positive voltage or negative pole coupling bolt become flexible, and prompting moves and the maintainer notes.Can one group when this system is installed additional in the transformer station of two group storage batteries operations construct one group and normally move, do not influence power grid security.
Description of drawings
Fig. 1 is the structural representation of the utility model transformer station accumulator bolted degree detection system.
Embodiment
Explain further details below in conjunction with the structure and the use principle of accompanying drawing to the utility model transformer station accumulator bolted degree detection system.
As shown in Figure 1; The utility model transformer station accumulator bolted degree detection system comprises accumulator 1; Accumulator 1 is provided with the coupling bolt 3 that has clamp nut 2; On the coupling bolt 3 clamp nut 2 below be provided with piezoelectric sensor 4, piezoelectric sensor 4 is connected with direct current cabinet supervising device 6 through signal wire 5.
Transformer station's accumulator bolted degree detection system that the utility model provided is provided with piezoelectric sensor 4 below the clamp nut 2 on each accumulator 1 coupling bolt 3, piezoelectric sensor 4 is connected with direct current cabinet supervising device 6 through signal wire 5.During use, with piezoelectric sensor 4 be installed in clamp nut 2 on the coupling bolt 3 below, and direct current cabinet supervising device 6 set alarming values.Piezoelectric sensor 4 can be monitored coupling bolt 3 fastening situation in real time, can also export to show coupling bolt 3 tautness linearity curves.When coupling bolt 3 became flexible to the alarming value scope, piezoelectric sensor 4 sent alerting signal to direct current cabinet supervising device 6, and direct current cabinet supervising device 6 can show that concrete which accumulator 1 negative or positive electrode coupling bolt 3 is loosening, and prompting moves and the maintainer notes.Can one group when this system is installed additional in the transformer station of two group storage batteries operations construct one group and normally move, do not influence power grid security.
