Abstract
The utility model relates to a battery discharge device, in particular relates to an automatic switching device used during half-capacity discharge of a battery. The automatic switching device avoids loss of power of a direct current power supply system during half-capacity discharge of the battery. The automatic switching device is characterized in that large capacity diodes are connected at the two ends of an air switch or a fuse in parallel. The automatic switching device has the following beneficial effects that the air switch or the fuse is disconnected, at the moment, a charge loop is cut off and the voltage of the battery is lower than that of a charger, but the battery can still supply power continuously through one-way connection of the diodes if the alternating current power supply loses power, and the battery is in the hot backup exit status, thus greatly enhancing the operation stability of the direct current power supply system during half-capacity discharge of the battery.
Description
Technical field
The utility model relates to the battery electric discharge device, guarantees the not storage battery half capacity discharge automatic bus of dead electricity of DC power system in specifically a kind of storage battery half capacity discharge work.
Background technology
As everyone knows; Owing to do not unify the monocell group half capacity electric discharge of standard in the electric power system so far; Therefore when relevant storage battery half capacity discharge work such as carrying out " power plant electric substation accumulator direct current supply device operation and maintenance technical regulation " " State Grid Corporation of China's DC power system overhaul of the equipments standard " was stipulated, the method that constituent parts is taked was multifarious, and there are common defectives in these methods; When carrying out storage battery half capacity discharge work, all need cut off charge circuit; This moment, charger and storage battery can't be subsequent use each other in the very first time, in case appearance is unusual, storage battery can't put into operation automatically when charger; Very easily cause the direct current dead electricity, cause great potential safety hazard.Also some unit does not carry out capacity check safely even to storage battery in order to protect for the moment, and above way has all had a strong impact on the reliability service of transforming plant DC power-supply system.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and when providing a kind of storage battery half capacity to discharge, charger is in case appearance is unusual, and storage battery can put into operation automatically, the storage battery half capacity discharge automatic bus that DC power system is reliable.
The utility model can reach through following measure:
A kind of storage battery half capacity discharge automatic bus is provided with circuit breaker, it is characterized in that circuit breaker two ends parallel diode, and diode one end is provided with fuse.
Circuit breaker two ends in the utility model are two diodes of parallel connection in the same way.
Circuit breaker is an air switch in the utility model, the short circuit that can take place at circuit or electric equipment, protects when seriously transshipping.
During use storage battery half capacity discharge automatic bus is installed on the charging circuit of storage battery, diode cathode one end of storage battery half capacity discharge automatic bus links to each other with storage battery, and diode cathode one end links to each other with charger.The breaker closing of storage battery half capacity discharge automatic bus during operate as normal is as subsequent use DC power supply; When needs carry out storage battery half capacity discharge work; Cut-off breaker, because the unidirectional conducting function of diode, charger can not be charge in batteries; But when power supply breaks down dead electricity; Storage battery still can not have the gap power supply, and battery pack is in the Hot Spare exit status, DC power system reliability of operation when greatly having strengthened the discharge of storage battery half capacity.
Description of drawings
Fig. 1 is the electrical block diagram of the utility model.
Fig. 2 is the concrete structural representation of using of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Storage battery half capacity discharge automatic bus as shown in Figure 1 is provided with circuit breaker 2, circuit breaker 2 two ends parallel diodes 1, and as can be seen from the figure, circuit breaker 2 two ends are two identical diodes of parallel connection in the same way, increase the ability that diode is handled bigger electric current.Diode one end is provided with fuse 3.Circuit breaker 3 is air switches in the utility model, the short circuit that can take place at circuit or electric equipment, protects when seriously transshipping.
As can be seen from Figure 2, during use storage battery half capacity discharge automatic bus 5 is installed on the charging circuit of storage battery, diode cathode one end of storage battery half capacity discharge automatic bus 5 links to each other with storage battery 6, and diode cathode one end links to each other with charger 4.The breaker closing of storage battery half capacity discharge automatic bus during operate as normal is as subsequent use DC power supply; When needs carry out storage battery half capacity discharge work; Cut-off breaker, because the unidirectional conducting function of diode, charger can not be charge in batteries; But when DC power supply breaks down dead electricity; It is load 7 power supplies that storage battery 6 still can not have the gap, and storage battery is in the Hot Spare exit status, DC power system reliability of operation when greatly having strengthened the discharge of storage battery half capacity.
