Product Specification

SPD Surge protect device Schneider type:SPD Surge protect device ABB type

Product Description

Usage and application scope
MQD1 type surge protective device (short name "SPD") is suitable for AC *0/*0 Hz,**0V and the following electric power systems,such as TT, IT, TN-S, TN-C, TN-C-S. It protects the electric network shocked by the thunder or over voltage .
Working condition:
  1.Height: not more than ***0m
  2. Operating temperature : normal *5~**0˚C     Enlarge range: **0~**0˚C
  3. Relative humidity: on condition that room temperature *0%~*0%
  4. Installed at no notability shocked and virated place
  5. Don't be contained in explosion medium,the medium such as air and dust (including conduction dust ) shouldn't come to the degree that can corrode metal or damage insulation.

Model and meaning

Tripping device
There¡¯s tripping device designed on the modular of the protector. When the protector is over heat or shocked, the tripping device can automatically separate it from the electric net, at the same time showing the indication signal. It¡¯s green when the protector is normal, red when tripping.
Alarm
The power of the alarm is supplied by AC**0V. In normal condition it is green and the opening contact is closed but the closing contact is open. It is with the function of alarming and showing: the alarm will sound and the green indicator lamp will change to red when the mould of the protective device is out of working. And the alarm will not stop until the operator pushes the stop press (but the red lamp is still showing). If the trouble can not be dealt within *4 hours, the alarm will sound again.
Remote signaling contact
The products can be produced available with the accessory of remote signaling contact. If one or more of modular of the protector is in malfuction, the contact will be closed, and sending the malfunction signal.

Main Structure and Operating Principle
In three-phase four- line system , three phase lines and one zero line are connected protective device to the earth cable . (figure 1 ) . In normal situation , the protective device is high resistance , when the over voltage brings for electric network shocked by thunder or other reasons , the protective device will rapidly transmit in ns , then lead the voltage into earth and protect the electric equipment . As the surge voltage through the protective device and after disappear it will recover to high resistance and not influence the normal operating. Pls refer to Fig.2 for the electric principal for the protector.
