Description

Novel charger

Technical Field

The invention relates to a charger, in particular to a novel charger.

Background

In recent years, with the rapid development of society, storage batteries or storage batteries are widely applied to a plurality of electric appliances, various vehicles and ships and the like, so that various chargers are produced by various manufacturers, most manufacturers adopt two charging modes, namely constant current or constant voltage, and single voltage and low power, and the service life of the storage batteries is greatly shortened, and the large-scale machinery is not suitable for the charger. The common charger on the market is basically composed of a common large-grade transformer, a common small-grade transformer, a common rectifier and the like, and the charger is short in service life, not durable and poor in safety performance, and brings inconvenience to people.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a novel charger which is firm in structure, high in performance, long in service life, wide in voltage selection, safe and reliable.

The purpose of the invention can be realized by the following technical scheme: a novel charger is characterized by comprising an ammeter, a pull-off clamp, a safety seat, a switch, a power line, a chassis of a case, a rubber foot pad, a current divider, a three-phase transformer, an insulating plate, a case shell, a lifting handle, a three-phase rectifier bridge, a voltage protection relay and a power supply cut-off alternating current contactor, the insulating plate is fixedly connected with the top of the three-phase transformer through the combined screws, the bottom of the three-phase transformer is fixed with the inner side of the bottom of the chassis base through the combined screws, the upper part of the chassis is fixedly connected with the chassis shell through a cross self-tapping screw, the handle is arranged at the top of the chassis shell and is fixed through a handle buckle, the case is also provided with an ammeter, function indicating lamps, a safety seat and a quick plug, and the shunt is arranged at the lower part of the outer wall of the left side of the chassis of the case and fixed through a cross-shaped combined screw.

In the novel charger, the bottom of the chassis is provided with a plurality of fixed casters which are fixed at four corners of the bottom of the chassis through wheel shafts.

In the novel charger, the chassis of the case is provided with the fan.

Compared with the prior art, the novel charger is designed with the optimal charging procedures of constant-current voltage limiting, constant-voltage current limiting and three-stage floating charging, and also adds the automatic battery voltage identification and capacity indication, the overload polarity is connected with the display lamp system in a reverse way, the process is completed fully automatically, the function of the charger is also added with the automatic input voltage selection protection, but the operation firmness far exceeds the inversion mode, so that the charger is applied to greatly increase the efficiency of the performance, and the service life of the storage battery is greatly prolonged.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in figure 1, the novel charger comprises an ammeter, a pull-off device 5, a clamp, a safety seat, a switch, a power line, a chassis 1 of a case, a rubber foot pad, a current divider, a three-phase transformer 4, an insulating plate, a case shell 2, a handle 3, a three-phase rectifier bridge 6, a voltage protection relay 7 and a power supply cut-off alternating current contactor 8, the insulating plate is fixedly connected with the top of the three-phase transformer 4 through the combined screws, the bottom of the three-phase transformer 4 is fixed with the inner side of the bottom of the chassis underframe 1 through the combined screws, the upper part of the chassis 1 is fixedly connected with the chassis shell 2 through cross self-tapping screws, the lifting handle 3 is arranged at the top of the chassis shell 2 and is fixed through the lifting handle 3, the case shell 2 is also provided with an ammeter, various function indicating lamps, a safety seat and a quick plug, the flow divider is arranged at the lower part of the outer wall of the left side of the chassis 1 of the case and is fixed by cross-shaped combined screws.

In more detail, the bottom of the chassis base 1 is provided with a plurality of fixed casters 9 and fixed to four corners of the bottom of the chassis base 1 through wheel shafts 10.

In further detail, the chassis base 1 is provided with a fan 11. The heat dissipation to the inside of the charger is performed by the fan 11, and the high heat generated when the charger starts to operate is reduced to improve the service life of the product.

The CLASS-1500 charger of the present embodiment is composed of a transformer, a control transformer, a rectifier bridge, an ac contactor, a time relay, a protection relay, a fan 11, and other main components, and a circuit diagram thereof is shown in fig. 2.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
