发那科数控机床中电源放大器的连接

和通用型数控系统不同，发那科系统采用了自己独有的电源系统进行供电，有的书上称为电源放大器，也有的书直接称为电源模块。

电源模块是作为一个独立的模块装在机床电气柜中，今天简单介绍一下电源模块的接线。首先将电源模块面板标示如下：

然后逐一介绍每个接口：

①—TB1，直流电源输出端

该接口与主轴放大器、伺服放大器的直流输 入端连接，为主轴放大器、伺服放大器提供DC300V电源。

②—状态指示

用发光二极管表示电源模块所处状态，出现异常时显示相关报警代号。

③—CX1A

单相AC200V输入接口。

④—CX1B

单相200VAC输出接口。

⑤—直流回路连接点状态指示

在该指示灯完全熄灭后，方可对模块电缆进
行各种操作，否则有危险。

⑥—CX2A

DC24V输出接口。

⑦—CX2B

DC24V输入接口。该接口与主轴放大器的CX2A相连接。

⑧—JX1B

模块连接接口。该接口一般与主轴放大器JX1A连接，作通信用。

⑨—CX3

主接触器控制信号接口。该接口是连接主 接触器控制信号，控制输入电源模块的三 相交流电的通断。

⑩—CX4

急停信号接口。该接口用于连接机床的急停信号，切断电源模块24VDC。

11—S1、S2

再生相序选择开关，一般出厂默认设定值为S1短路。

12—电源模块电流电压检查用接口

13—三相交流电输入端

The new VD4 vacuum circuit breaker is the perfect combination of ABB’s renowned R&D and manufacturing technology of arc extinguishing chamber and pouring pole, and advanced operating mechanism R&D, design and production technology.
The quench chamber of the VD4 medium pressure vacuum circuit breaker is poured integral in epoxy resin. The overall pouring pole structure is stronger, which can provide more adequate protection for the vacuum arc extinguishing chamber, and can eliminate the influence of dust and moisture on the external insulation capacity of the arc extinguishing chamber.
The arc extinguishing chamber permanently seals the main contact of the switch in a vacuum environment to form an arc breaking unit. Break the current in a vacuum
Vacuum circuit breakers do not require arcing and insulating media. In fact, there is no ionized material in the chamber. In any case, when the contacts are separated, the arc passage between the contacts consists solely of the metallic vapor of the contact material. The arc can only be maintained by external energy. When the main loop current disappears at natural zero crossing, the arc cannot be maintained. At this point, the rapidly decreasing current carrier density and the rapidly condensing vacuum metal vapor quickly restore insulation between the contacts. The vacuum chamber thus restores the insulation capacity and the ability to withstand the system’s transient recovery voltage, eventually extinguishing the arc.

Specially designed contact geometry and contact material, as well as very short arc burning time and very low arc voltage, so that the contact ablative degree is very low, ensure the arc extinguishing chamber long life. In addition, the vacuum protects the contacts from oxidation and contamination.
EL type operating mechanism
The contact of modern vacuum arc extinguishing chamber requires low separation speed, small stroke and light weight, and only requires the mechanism to provide little operating work. This ensures low wear on the operating system and means that the circuit breaker requires minimal maintenance. The VD4 circuit breaker uses a spring-loaded, free trip modular mechanical operating mechanism. The operation performance of circuit breaker has nothing to do with the specific operator. The operating mechanism is simple in concept and easy to use. It can be freely selected with secondary accessories that can be easily and quickly installed. The simple design idea brings high reliability of components.
