When quitting work, do not send control signal, so that controllable electric power KC becomes low level, so that the 42nd Audion Q42 turns off, and causes the colelctor electrode of the 42nd audion Q42 and the positive pole BAT+ of accumulator to have isoelectric level simultaneously, Hence in so that the base stage of equipotential 41st audion Q41 becomes high level with the colelctor electrode of the 42nd audion Q42, Hence in so that the 41st audion Q41 conducting connected with the 41st resistance R41, owing to the 41st resistance R41 selects The resistor of small resistance value, therefore increases the electric current of turning circuit, thus decreases discharge time.

This discharge circuit 13 utilizes the 41st audion Q41 and the 42nd audion Q42, when normally working, touches Send out the 42nd audion Q42 conducting connected with the 43rd resistance R43 with bigger resistance, thus reduce greatly and lead The electric current of circuit passband, therefore reduces system loss；When quitting work, the 41st resistance making with there is small resistance value 41st audion Q41 conducting of R41 series connection, thus increase the electric current of turning circuit, reduce discharge time.So it can drop Low cost, reduction are lost, can reduce discharge time.

In the present embodiment, this discharge circuit 13 also includes the 42nd resistance R42, the transmitting of the 41st audion Q41 The 42nd resistance R42 ground connection is passed through in pole.42nd resistance R42 is current-limiting resistance, is used for carrying out overcurrent protection.This electric discharge Circuit 13 also includes the 44th resistance R44, and the emitter stage of the 42nd audion Q42 passes through the 44th resistance R44 ground connection. 44th resistance R44 is also current-limiting resistance, is used for carrying out overcurrent protection.

It is noted that in the present embodiment, above-mentioned 41st audion Q41 is NPN type triode.Above-mentioned 40th Two audion Q42 are also NPN type triode.Certainly, under the certain situation of the present embodiment, the 41st audion Q41 and 42 audion Q42 can also select PNP type triode, but at this moment the structure of discharge circuit 13 also to change accordingly.

In a word, due to the fact that and be provided with lightning protection circuit 14, thus can effectively lightning protection, improve security of system performance；Separately Outward, charging circuit 11 has easy for installation, with low cost and service-strong advantage, and control circuit 12 has good self-starting Ability, it is to avoid the endless loop state often occurred in prior art, the discharge circuit 13 in the present invention and the first traditional electricity Hold self discharge circuit to compare, improve system effectiveness, and decrease loss simultaneously；With traditional the second electric capacity self discharge circuit Compare, reduce cost, and add service life simultaneously.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
