报警功能点
Alarm functional points
磁助式电接点开关也就是电源开关,整个电源回路的开断是通过内部的机械结构达到预先设定的限值时触发电接点开关。
Magnetic snap-action contact is also auxiliary power switch. The entire power circuit is disconnected or connected by activating the contact when the preset limit value is reached through internal mechanical mechanism.
投诉/更换/修理
Complaint/replacement/repair
售后服务时请给出生产编号和产品型号,生产编号印在表盘上,产品型号印在标牌上。
At customer service, please provide with the production number and product model. The production number is printed on the dial, while the product model is printed on the nameplate.
SF6-气体密度继电器/远传密度继电器必须长时间恒温才能达到温度补偿作用(至少两小时) 。
偿作用(至少两小时) 。
SF6- gas density monitor/ remote gas density monitor must be kept in constant temperature for a long time (at least two hours) so as to achieve temperature compensation.
只有厂家可以进行维修,不允许开仪表,否则会使显示和开关点产生误差。
No one other than the manufacturer is allowed to disassemble the instrument for fear that any error may occur to the display and switch point.
B.电气接口
Electrical interface
接线必须由经过培训的人员操作 .接线分布和开关功能都在仪表型号牌上给出,并注明了接线柱和接地柱.规定供电电线必须考虑仪表的大电流需求量并符合 IEC227 或 IEC245 标准.
The wirings shall be performed by professionally trained personnel. Wiring distribution and switching functions are displayed on the instrument type plate with terminal binding posts and ground pole also indicated. The specifications of power line must allow for the maximum current requirement of the instrument and comply with IEC227 or IEC245.
数据处理:
温度:Temperature = ( Temperature High | Temperature Low)/100 ℃
例:Temperature High=0xF6;Temperature Low=0x05
Temperature = 0xF605/100 = -25.55 ℃
压力:Pressure = ( Pressure High | Pressure Low)/1000 MPa
例:Pressure High = 0x12,Pressure Low = 0x34
Pressure = 0x1234/10000 = 0.4660 MPa
密度:Density = ( Density High | Density Low)/1000 MPa
例:Density High=0x56;Density Low=0x78
Density = 0x5678/10000 = 2.2136MPa
返回的温度、压力、密度数据为2字节有符号整数。
密度以对应20℃下的压力P20表示,单位MPa.
压力和密度用压力表示,若转化为相对压力,减去当地大气压。
使用和维护
Use and maintenance
密度继电器/远传密度继电器应垂直安装,用在室外的密度继电器/远传密度继电器应避免阳光直射到仪表上,好在仪表上加装防护罩。
Gas density monitor/remote gas density monitor shall be installed upright. For a gas density monitor used outdoors, direct exposure to sunlight is not allowed, and it is advisable to use a shield.
密度继电器/远传密度继电器安装部位应能较真实地反映设备内气体的温度。
Gas density monitor/remote gas density monitor shall be erected at a proper position to reflect the temperature of gas in relevant equipment.
用肥皂水浸湿的擦布清洁仪表,要清洁接线盒或插头时要先把电源断开,再接通电源前确保所有部件不潮湿。
Clean the instrument with a wiping cloth soaked in soap water. Cut off the power supply before cleaning the terminal box or plugs. Make sure that all components are dry before turning on the power again.
