Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.Referring to Fig. 2, Fig. 2 is the schematic diagram of traditional off-line electric discharge device, and traditional charging method is to pull out fuse 10a, the 10b of storage battery 10; Let storage battery 10 be in off-line state, charger 9 gives load 12 power supplies, and charger 9 can not charge by accumulators 10; Discharge instrument 11 is received discharge on the storage battery 10; Storage battery 10 can not in time give load 12 power supplies when shortcoming was the civil power interruption, load 12 outages, and the regular event of cabinet is protected in influence.
As shown in Figures 2 and 3, zero second switching protection of the described storage battery of the utility model comprises three bindiny mechanisms; Three bindiny mechanisms are divided into 5, one diodes 2 of 6,7,8, one contactors of power folder; 3, one overcurrent protective devices 4 of an open type air switch.Contactor 5 detects industrial-frequency alternating current.
The positive pole of diode 2 is connected with lead 1, and negative pole is connected with conduction 1a.Open type air switch 3 is connected with lead 1,1a.
When civil power is arranged; Contactor 5 actions; Closed between the common 5c of contactor 5 and the normally opened contact 5a; The electrode line of storage battery 10 is connected with the electrode line of discharge instrument 11 through common 5c, normally opened contact 5a, lead 1b, the power folder 8 of power folder 7, lead 1a, overcurrent protective device 4, contactor 5; Discharge instrument 11 regular pictures, current direction are storage battery 10 anodal common 5c to power folder 7, lead 1a, overcurrent protective device 4, contactor 5, normally opened contact 5a, lead 1b, power folders 8 positive poles to discharge instrument 11, again by the negative pole of discharge instrument 11 negative pole to storage battery 10.During contactor 5 adhesives, pull out the electrode line of storage battery 11 and the fuse 10a between charger 8 output cathodes (red line), owing to diode 2 reverses biased are ended; Charger 9 can not charge by accumulators 10; Charger 9 gives load 12 power supplies, and current direction is: by charger 9 positive poles, to load 12 positive poles; To load 12 negative poles, arrive charger 9 negative poles again.
