Abstract
The utility model belongs to a protection apparatus for a storage battery group with over high temperate in a lifting electromagnet control device. The protection apparatus being composed of a storage battery group1, a charging control circuit 2, temperature control relays 3, and a contactor 4 is characterized in that the three temperature control relays 3 are installed at the surface of the storage battery group1; control nodes of the temperature control relays are connected in series to the contactor 4; and the charging control circuit 2 and the storage battery group1 are connected. With the protection apparatus, the storage battery group can be prevented from being over heated during charging, thereby protecting the storage battery group and prolonging the service life of the storage battery group.
Description
Technical field
The utility model belongs to electromagnet lifting appliance field, particularly the protective device of batteries excess Temperature in a kind of controller for electromagnetic crane.
Background technology
In controller for electromagnetic crane, for the safety of lifting operation, batteries is absolutely necessary as the stand-by power supply of power failure or fault guarantor magnetic; In controller for electromagnetic crane, conventionally adopt 18 batteries series connection, in the time having a joint battery tension reduction or no-voltage, the charging voltage that should be born by this joint storage battery will be distributed to the storage battery of other series connection, thereby other storage battery is produced to be overcharged, storage battery can generate heat, be out of shape owing to overcharging, until damage; At present, also do not take effective technology protection measure to storage battery is overheated in lifting electromagnet industry, often because overcharge of a battery damages.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, the protective device of batteries excess Temperature in a kind of controller for electromagnetic crane is provided.
The technical scheme that the utility model technical solution problem adopts is: the protective device of batteries excess Temperature in a kind of controller for electromagnetic crane, comprises batteries 1, charging control circuit 2, thermorelay 3 and contactor 4; It is characterized in that, on batteries surface, 3 thermorelays are installed, thermorelay control node is series in contactor, and charging control circuit is connected with batteries.
The beneficial effects of the utility model are: prevent that batteries is overheated, protection storage battery, increasing storage battery service life.
Brief description of the drawings
Illustrate with embodiment below in conjunction with accompanying drawing.
Accompanying drawing is the protective device electrical principle calcspar of batteries excess Temperature in controller for electromagnetic crane.
In accompanying drawing: 1-batteries; 2-charging control circuit; 3-thermorelay, 4-contactor.
Embodiment
Embodiment, with reference to accompanying drawing, the protective device of batteries excess Temperature in a kind of controller for electromagnetic crane, comprises 1-batteries; 2-charging control circuit; 3-thermorelay, 4-contactor; It is characterized in that, on batteries 1 surface, 3 thermorelays 3 are installed, thermorelay control node is series in contactor 4, and charging control circuit 2 is connected with batteries 1.
The operation principle of this utility model is: temperature is during lower than 45 DEG C, and thermorelay 3 nodes are connected, contactor 4 electric, three-phase alternating current becomes controlled Rectified alternating current by charging control circuit 2 batteries is carried out to trickle charge; In the time that accumulator meter surface temperature reaches 45 DEG C, any one node in 3 thermorelays disconnects and all can make contactor 4 dead electricity, turn-offs charging control circuit 2, makes batteries protected.
