Furthermore, the air inlet controllable shutter and the air outlet controllable shutter are both provided with driving motors, and the driving motors are connected with a charging controller carried by a direct current charger.

Compared with the prior art, the utility model has the following technical effects:

according to the utility model, smoke and temperature in the direct current charger are detected, the charging controller issues a control command to the actuating mechanism, and the air inside and outside the equipment is isolated by closing the air inlet and the air outlet and the heptafluoropropane gas filled in the cabinet, so that the equipment can effectively extinguish fire in time.

The heptafluoropropane gas fire-fighting system in the direct current charger has the following main effects:

(1) by detecting smoke and temperature inside the direct current charger, when smoke is detected inside the equipment, the charging controller controls the charger to be timely and effectively disconnected from the vehicle, the charger is connected with the main loop of other equipment, and charging equipment and charging vehicle loss caused by ignition of the equipment are reduced.

(2) The air inlet and the air outlet of the charger are closed, so that resistance external air enters, an effect of isolating a fire disaster in the equipment from an external space is achieved, and the fire disaster range is reduced.

(3) Through the mode that heptafluoropropane gaseous put out a fire in the direct current battery charger, after the inside fire of battery charging outfit is extinguished, need not clear up the equipment is inside, be favorable to the inside device of equipment to inspect and restore, furthest's reduction the cost of equipment clearance and maintenance, reduce the customer loss.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

Wherein:

1. a smoke sensor; 2. a temperature sensor; 3. a control valve; 4. a fire extinguishing gas tank; 5. a controllable shutter for the air inlet; 6. the air outlet is provided with a controllable shutter; 7. a housing; 8. a fire extinguishing pipeline.

Detailed Description
