一、 产品用途

QJ 系列气体继电器（以下简称继电器），是油浸式变压器所用的一种保护装置，由于变压器内部故障而使油分解产生气体或造成油流涌动时，使继电器的接点动作，接通指定的控制回路，并及时发出信号或自动切除变压器。 二、工作原理

变压器正常工作时，继电器内是充满变压器油的。如变压器在运行中出现轻微故障，因变压器油分解而产生的气体将聚集在继电器容器的上部，迫使继电器浮子下降，当浮子降至某一限定位置时，磁铁使信号接点接通，发出报警信号。若变压器漏而使油面降低，同样发出报警信号。如果变压器内部发生严重故障，将会出现油的涌浪，在管路内产生油流，冲击继电器的挡板运动。当挡板运动到某一限定位置时，磁铁使跳闸接点接通，切断与变压器连接的所有电源。 三、 技术参数

（1）QJ 4-25继电器外型及尺寸如图A 所示，QJ 1-50、80，QJ 4-50、80继电器外形尺寸如图B 所示，尺寸见表三。

（2）继电器安装在变压器油箱与储油柜之间的连接管路中，安装时使继电器上的箭头指向储油柜一侧。

（3）安装完毕后，打开连接管路中的油阀，同时打开气塞排出气体，使继电器内充满变压器油，当气塞有油排出时关紧气塞。

（4）从气塞处打进空气，可以检查“信号”接点动作的可靠性。 （5）将罩拧下，按动探针，可以检查“跳闸” 接点动作的可靠性。 五、 注意事项

（1）新出厂的继电器安装使用前必须先取出继电器芯子，拆除运输固定用的绑扎带。

（2）继电器必须经专用的试验装置检验后方可安装使用。

（3）挡板一侧装有弹簧，改变弹簧的长度，可以调整跳闸接点动作的油流速度。其余各部件不得随意调动。

（4）更换或增添磁铁及干簧管接点附近的零件时，应选用非导磁材料。 （5）磁铁不能剧烈振动，不能放在强磁场及超过100°C 和低于-40°C 的环境中。

（6）干簧接点不得随意拆、卸、特别是根部引线不允许任意弯折以免损坏。

1、Application

The Gas relay series QJ is protective device for oil immersed transformer. If a fault causes gas to be generated in the transformer or a heavy surge of insulating oil the Gas relay shall be in operation, the alarm signal is initiated and/or the transformer is tripped automatically. 2、Principle of design

When the transformer is operating normally, the Gas relay is completely filled with insulating oil .If a fault causes gas to be generated in the transformer, the bubble will filter along towards the conservator and accumulated at the highest point in the Gas relay. As the amount of gas coquette increases and the oil level in relay fall as a result, the cup also falls and eventually reaches point where it actuates the magnetic switch with the permanent magnet and so initiated the alarm signal. If the oil loses, the alarm signal is also initiated A violent generation of gas accompanied by a heavy surge of insulating oil results in operation of baffle plate. the magnetic is actuated by the permantmagnet on the baffle plate so it trips the transformer.

When acceleration is 4g at vibration frequency of 4～20Hz,the relay shall not do any. 4、installation and application

(1) The overall size of QJ4-25 Relay is shown as Fig. A. The overall size of QJ1-50 、80，QJ 4-50、80 Relay is shown as Fig. B. Seeing Table 3 for the size.

(2) The Gas relay is fitted in pipeline between the tank and conservator. pay special attention to the arrow on the housing the conservator.

(3) After installation, open the oil valve in the connecting tube, enable the relay fulfilled with transformer oil, and when the oil discharge of air plug close air plug.

(4) Air pumped form the air plug, the reliability of “Signal” contacting motion can be checked.

(5) Twist the cover and press the pin, the reliability of “Trip” contacting motion can be

checked.

5、Note

(1) Before the newly-produced relay installed and used, the relay chip must be taken out and the locked banding used during the transportation should be demolished. (2) The Gas relay must be checked by special device, then can mounted.

(3) The spring on the baffle plate can changed the length, adjusting the value for tripping. The other parts of the Gas relay can`t change at will.

(4) Replacing or adding some parts near the permanent magnet and magnetic switch, the non-magnetic material must be used.

(5) The permanent magnet can be not intensely vibrated or in strong magnetic field, The

permissible operating temperature is from -40°C to 100°C.

(6) The magnetic switch can’t dismantle and the end of leads can`t bend at will. 六、 Structure outline and dimensions
