继电器(隆辉)中文说明书

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，在变压器运行中由于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，以接通指定的控制回路，并及时发出报警信号或切除信号，从而达到保护变压器的目的。

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，当变压器在运行中出现轻微故障时，因变压器油分解而产生的气体将积聚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。

若因变压器漏油而使油面降低，同样发出报警信号。

当变压器内部发生严重故障时，油箱内压力瞬时升高，将会出现油的涌浪，从而在管路内产生油流，冲击继电器的挡板运动。

当挡板运行到某一限定位置时，磁铁使跳闸接点接通，将变压器从电网中切除。

三、技术参数
1、工作温度-30℃~ +95℃
2、接点容量AC220V 0.3A COSФ≤0.6
DC 220V 0.3A S≤5 ×10 -3S
3、工作特性表一
4、密封性能
继电器充满变压器油，在常温下加压200kpa，持续20分钟无渗漏。

5、绝缘性能表二
6、抗震性能
当振动频率在4~20Hz（正弦波），加速度4g时，继电器不误动作。

四、安装与使用
1、QJ4-25继电器外形及接线图如图A所示；QJ1-50、80 QJ4-50、80继电器外形及接线图如图B
所示，尺寸见表三。

2、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。

然后必须经专业的检验
部门检验后方可安装使用。

3、挡板一侧装有弹簧，调节与弹簧连接的调节杆，改变弹簧的长度，可以调整跳闸接点动作的油
流速度（动作流速整定工作应由专业人员在专用流速校验设备上进行）。

其余各部件不得随意调动。

4、继电器安装在油浸变压器油箱与储油柜之间的联接管路中，继电器上的箭头必须指向储油柜一
侧。

5、安装完毕后，打开联接管路中的油阀，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。

6、从气塞处打进空气，可以检查“信号”接点动作的可靠性。

7、将探针罩拧下，按动探针，可以检查“跳闸”接点动作的可靠性。

五、注意事项
1、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。

2、更换或增添磁铁及干簧接点附近的零件时，应选用非导磁材料。

3、磁铁不能剧烈震动，也不能放在强磁场及超过100℃和低于－40℃环境中。

4、经检验后的继电器各部件不得随意调动。

5、为了保障您的利益，敬请您在使用本产品前及遇到故障时，详细阅读使用说明书，以便我们为
您提供最优良的服务。

1、Application
The Gas relay series QJ is protective device for oil immered transformer.If a fault causesgas to be generated in the transformer or a heavy surge of insulating oil the Gas relay shall be in operation,the alarm signal is initeated and/or the transformer is tripped automatically.
2、Pirnciple of design
When the transformer is operating normally,the Gasrelay is completely filled with insulating oil .If a fault causes ges to be generrated 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 couecte increses and the oil level in relay fall as a result,the cupalso falls and eventually reaches point where it actuates the magnetic switch with the permanent magnet and soinitiated the alarm signal.If the oil loses,the alarm signalis slso 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.
3、Technical datd
(1) Working temperature:-30°C～95°C
(2) Switch Capacity:AC220V0.3A COSφ≤0.6
DC220V0.3A S≤5×10-3S

(4)
200kPa,Continued 20 min and withont any leakage.
When acceleration is 4g at vibration frequency fo 4～20Hz,the relay shall not do any.
4、nstallation and application
(1)The overall sive of QJ4-25 Relay is shownas Fig. A.The overall sive of QJ1-50 、80，
QJ4-50、80 Relay is shown as Fig. B.Seeing Table 3 for the size.
(2)The Gas relay is fitted in pipeline between the tankand conservator.pay special
attention to the arrow on the housing the conse rvator.
(3)For filling oil,please all valves in the pipeline between the tank and conservator,blled
the housing via the bleeder and then ciosed.

bechecked.
(5)Cover twisted down,pin prossed,the reliability of “Trip” contacting motion can
bechecked.
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 vibratied or in strong magnetic field,
The permissible operating temperature is from -40°C to 100°C.
