Abstract
A kind of storage battery defends the reverse connection protective device, apply to the generating set, including storage battery and electrical relay; the positive pole of the storage battery is grounded through a coil of the relay, and the storage battery is connected with the generator set through a contact of the relay. The utility model has simple structure and is used in strong current environment of the generator set; the protection to the generator set is enhanced, the safety is improved, unnecessary cost is prevented, the application range is wide, and the social benefit and the economic benefit are higher.
Description
Technical field
The utility model relates to accumulator protecting field, specially a kind of battery protection apparatus preventing reverse connection.
Background technique
The starting of generating set and control signal need to provide DC power supply, are generally protected by battery and charger
Card.In practice, due to the complexity of route, battery is easy to appear the case where wiring is reversely connected, and will cause battery damage, seriously
The case where may result in personal safety, and also result in generating set operation irregularity, increase the cost of product, waste
Resource.
Existing reverse connecting protection technology all rests on radio-frequency stage, is all light current, and circuit is complicated, is not suitable for forceful electric power device.
The utility model provides a kind of simple protective device of structure, strengthens the protection to generating set, improves safety, prevents
The generation of unnecessary cost, applied widely, Social benefit and economic benefit with higher.
Summary of the invention
A kind of battery protection apparatus preventing reverse connection is applied on generating set, characterized by comprising: battery and relay
Device；The anode of battery is grounded by the coil of relay, and battery connects generating set by the contact of relay.
Further, the relay is heavy-current relay；Forceful electric power environment suitable for generating set work.
The utility model has the advantages that there is the prior art to compare, the utility model structure is simple, is used in the forceful electric power environment of generating set；
The strong protection to generating set, improves safety, prevents the generation of unnecessary cost, applied widely, with higher
Social benefit and economic benefit.
Detailed description of the invention
Fig. 1: the normal diagram of wiring of battery；
Fig. 2: reverse connection of accumulator circuit diagram；
In figure: 1- battery；2- relay；3- generating set.
Specific embodiment
Now in conjunction with attached drawing, the utility model is further described in detail.
A kind of battery protection apparatus preventing reverse connection is applied on generating set 3, including battery 1 and relay 2；Electric power storage
The anode in pond 1 is grounded by the coil of relay 2, and battery 1 connects generating set 3 by the contact of relay 2.
Working principle: when battery 1 just connects, 2 coil of relay obtains electric, and 2 contact closure of relay, generating set 3 is just
Often work；
When battery 1 is reversely connected, 2 coil of relay must not be electric, and 2 contact of relay disconnects, and generating set 3 stops working, i.e.,
Effective protection is done to battery.
The utility model strengthens the protection to generating set, strengthens safety.Prevent the generation of unnecessary cost, machine
Structure is simple, applied widely, Social benefit and economic benefit with higher.
