Circuit breaker of Auto Changeover Switch 250A/3P transfer switch

Product Overview

Description

 

 

 

 YEQ2 series automatic transfer siwtch is the best development of the company generation produts. Mostly used to monitor the power supply circuits, When main power failured, it will change over to backup power by automarucally, thus completing the transformation of power system. At present, in practicular suited for the important electricity power places where disallow the failure, in order to meet the needs of utility-generators work with a varity functions, the product applied in 200V,AC 50Hz,rated current from 10A to 1250A(CB class) automatically switch products.

 

 Structure and festures

 

YEQ2 series intellgent dual power automatic switch is made up of two unites in 3 Pole and 4 Pole of MCCB and (auxiliary contact, alarm contact), the mechanical interlocking transmission, intelligent controller and other components. It has the intergral style and split type with two kinds mechanism. Integral controller is equipped with a base and executing agencies; Split type is intelligent controller installed in the panem user take the base by implementing agencies to install into the cabinet controller with about 2m cables.

1. Reliable mechanical interlock between the two circuit breakers and electrical interlock device. Eeliminate the two devices closing completely at the same time.

2. SCM intelligent controller used to control the core hardware is simple and powerful, expansion of convenience, high reliabillity.

3.It has a short circuit, over load protection functions, over voltage,under voltage,loss phase automatic transfer function and intelligent alarm function.

4. Automatic switching external parameters can be set free.

5. Operation of Intelligent motor protection.

6. The control circuit devices with fire, fire control center to a contro signal into intelligent controller. Two sets circuit breaker will enter a starting breaking.

7. There us a computer network inteface for acgieving remote control four remote telemetry functions.

 

Beauty in appearance,reliable in quality, long life and easy in operation

 

A new intelligent modular design

 

 

Function of the controller

A type controller

A controller(basic type) and switch bodyinstall together, as per working voltage are normally or not decides how to work conversion.

Function

1. Alternative work by automatic and manual operation

2. Monitiring the two sources,whether is loss phase, under voltage, loss voltage and such abnormal conditions, the indiction show whether in located normal voltage.

3. Conversion type is Self-input and self-recover.

Electric Performance

1. Rated working voltage:AC220V/50Hz

2.Transfer delay time: 0.5s

 

B Type controller

B Type controller adopting microprocessor programmed control,linking with switches bodys together cleverly, easy to operates, function is powerful, and increased C controller and D type LCD display fission controller on the basis of the B model controller.

Function

 

• Accurately shows two ways three phase voltage, frequency and switch state capacity in two sources;
• Allow user allows to monitor the scene,the control center to amend the parameter of working status and transfer delay time;
• Set arbitrarily self-input and self-revover self-input without self-recover, utility-generator models
• Fire Alarm linkage- conversion to 0;
• Manual and automatic conversion mode alternative function;
• Under the utility-generator model with a send off signal to generator;
• Conversion and delay time can be set arbitrarily;
• With a strong anti-jamming capability, suitable for the strong electromagnetic interference using in a compl- exa environment

 

Electric Performance

 

• Working voltage: AC220V / 50Hz;
• Transfer delay time: 0.5s-90s continuous adjustabled;
• Return delay time: 0.5s-90s continuous adjustabled;
• Lack voltage transfer value:145V-210V continuous adjustabled;
• Over voltage transfer value:230V-300V continuous adjustabled
• Transfer time: not more than 4s
