As a kind of electromagnetic switch, the contact (normally open and normally closed) of the intermediate relay and the rated voltage of the working coil of the intermediate relay should be paid attention to.

中间继电器的使用注意事项

Precautions for use of intermediate relay

一、中间继电器

1、 Intermediate relay

中间继电器是一种电磁动作开关。

The intermediate relay is an electromagnetic switch.

中间继电器由胶木外壳、衔铁和线圈以及动静触点组成。

The intermediate relay is composed of bakelite shell, armature, coil and dynamic and static contacts.

当线圈接通电源时，衔铁动作，带动触点闭合或断开电路，从而达到多组开关同时动作的目的。

When the coil is connected to the power supply, the armature acts to drive the contact to close or open the circuit, so as to achieve the purpose of simultaneous action of multiple groups of switches.

一般中间继电器在电路中起着小功率信号变换作用，也可控制大容嗽的触头动作，并能扩大受控电器的触头数量。

In general, the intermediate relay plays the role of small power signal conversion in the circuit, can also control the contact action of large capacity, and can expand the number of controlled electrical contacts.

二、中间继电器的使用注意事项

2、 Precautions for use of intermediate relay

使用中间继电器时，要注意二个问题：

When using the intermediate relay, we should pay attention to two problems

1、中间继电器的触头较多，一鲜有8对、6对等，并分常开触点和常闭触点。

1. There are many contacts in the intermediate relay, including 8 pairs of contacts and 6 pairs of contacts.

但触头的容量较小，没有主、辅触头之分，也没有灭弧装置，因此在应用中间继电器控制电动机启停时，只能用额定电流小于5A的小型电动机，并选用一种大型号的JZ7型中间继电器控制。

But the capacity of the contact is small, there is no main contact and auxiliary contact, and there is no arc extinguishing device. Therefore, when using the intermediate relay to control the start and stop of the motor, only the small motor with the rated current less than 5A can be used, and a large JZ7 type intermediate relay can be used.

2、中间继电器的工作线圈的额定电压有多种，在应用中一定要使接人中间继电器线圈的工作电压符合中间继电器线圈的额定电压的要求。

2. There are many kinds of rated voltage of the working coil of the intermediate relay. In the application, the working voltage of the connecting intermediate relay coil must meet the requirements of the rated voltage of the intermediate relay coil.
