Abstract
The utility model discloses a storage battery isolation protection device. The storage battery isolation protection device comprises connecting mechanisms, a diode and an over-current protection device, and the diode is connected with the over-current protection device in series between the two connecting mechanisms and through a conductive wire. The over-current protection device comprises a fuse wire and an air switch, wherein the fuse wire is connected with the air switch in series. By means of the storage battery isolation protection device, on the condition of disconnection of one storage battery or a plurality of storage batteries, a discharging return circuit is kept supplying power to a load return circuit, troubles of one-by-one disassembly of storage batteries are avoided, the problem that bolts need unscrewing when storage batteries need replacing and therefore outage risks can occur probably is resolved, zero second switching of electricity is ensured, and the problems that change of internal resistance of storage batteries is too large to lead to disconnection of the discharging return circuit and reverse of the voltage direction are solved.
Description
Technical field
The utility model patent relates to a kind of protective circuit device, specially refers to a kind of storage battery isolating and protecting device.
Background technology
Storage battery be a kind of discharge into to a certain degree after, through overcharging and can restoring the battery of continuous usefulness, storage battery typically refers to lead acid accumulator, it is a kind of in the battery, belongs to secondary cell.It utilizes outside electric energy to make inner active material regeneration when charging, is electrical power storage chemical energy, again chemical energy is converted to electric energy output when needing discharge.Modern electric industry communications industry need to provide back-up source by storage battery, and storage battery occupies an important position.
Safeguarding storage battery, to be operated in good state by it be very important, maintenance free cell has several method usually, a kind of is to be connected to the line detector, unclamp the battery screw, patrolling and examining line pressure inside, if at this time suddenly because some reason has a power failure, battery is powering load in time, will cause very major injury to the loop; When some storage batterys need to be changed through in a few years operation, storage battery was changed section by section, waste time and energy, and might be because mains failure cause the storage battery power supply loop short time to interrupt.
The utility model content
The purpose of this utility model is to provide a kind of storage battery isolating and protecting device for the existing problem of existing battery service, this storage battery isolating and protecting device is by adopting the loop protection device, can be in the situation that disconnect one or several storage batterys, keep discharge loop to the power supply of load circuit, saved the one by one trouble of storage battery dismounting, solved when changing storage battery and unclamped the dangerous problem of issuable outage that screw causes because of needs, switched in zero second in the situation that guarantee electric power, the staff can worry that the outage problem dismantles relievedly and change storage battery; Also can solve in addition storage battery and open circuit the polarity of voltage indirect problem because internal resistance changes the discharge loop that causes more greatly.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of storage battery isolating and protecting device is characterized in that, comprises two bindiny mechanisms, diode and overcurrent protective devices, and described diode and overcurrent protective device are serially connected between two bindiny mechanisms by wire.
Described storage battery isolating and protecting device a kind of embodiment be that described bindiny mechanism is the power folder that is respectively red and black.
Described storage battery isolating and protecting device a kind of embodiment be that described overcurrent protective device comprises fuse and air switch, described fuse and air switch serial connection.
The beneficial effects of the utility model are: can be in the situation that one or several storage batterys of disconnection keep discharge loop to the power supply of load circuit; Having saved needs the one by one trouble of dismounting storage battery; Solved when changing storage battery and unclamped the dangerous problem of issuable outage that screw causes because of needs; Guarantee that electric power switched in zero second, had guaranteed the safety in loop; Solve storage battery and open circuit the polarity of voltage indirect problem because internal resistance changes the discharge loop that causes more greatly; Simple in structure, practical.
Description of drawings
Fig. 1 is storage battery isolating and protecting device schematic diagram described in the utility model.
Fig. 2 is the application drawing of storage battery isolating and protecting device described in the utility model when the dismounting storage battery.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1; schematic diagram for a kind of execution mode of storage battery isolating and protecting device described in the utility model; described storage battery isolating and protecting device comprises anodal bindiny mechanism, negative pole bindiny mechanism, diode 4 and overcurrent protective device, and described overcurrent protective device comprises fuse 3 and air switch 5.
Described anodal bindiny mechanism is a red clip 1, and described negative pole bindiny mechanism is a black clip 2, so that the resolution when using; Described two bindiny mechanisms can also be the power folders that has marked sign symbol.
Described red clip 1, black clip 2, fuse 3, diode 4 and air switch 5 serial connections, positive pole one end of described diode 4 is connected with black clip 2, negative pole one end is connected with red clip, and fuse 3 and air switch 5 are serially connected between two bindiny mechanisms by wire.
The used wire of described storage battery isolating and protecting device is the ultra-soft wire.
Workflow of the present utility model is as follows:
1) as shown in Figure 2, first red clip 1 is connected across on the current supply circuit the anodal 8a place that a joint or some joints are disassembled storage battery 7, black clip 2 is connected across a joint or some joints are disassembled the negative pole 8b place of storage battery 7, at this moment, electric current flows through from the black clip 2 of described storage battery isolating and protecting device, through flowing out from red clip 1 behind air switch 5, diode 4 and the fuse 3, form the closed-loop path;
2) electric current of the storage battery to be removed 7 of battery isolating and protecting device inside flows into from red clip 1, through diode 4 time, because of diode 4 unilateral conduction end, storage battery 7 place circuit to be removed will not have electric current to pass through; But this moment is dismounting storage battery 7 to be removed just;
3) new storage battery is installed after, the described storage battery isolating and protecting device of dismantling.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
