HSM2000 Transformer Oil Dissolved Gas Monitoring System

System components HSM2000 dissolved gases in transformer oil transformer oil online monitoring system consists of gas line monitoring device and background monitoring and management software in two parts. Transformer Oil Gas Monitoring field device consists of oil and gas separation module, gas sensor module, acquisition module, communication module, display module composed of several parts and temperature control can be achieved in transformer oil gas collection, computing, display and fault diagnosis. Device monitoring and management software can be run from the back alone, but also matching background monitoring network management software on-line monitoring system. HSM2000 background monitoring and management software, according to the gas concentration, transformer operating conditions in real-time display and fault alarm. A background monitoring and management software can simultaneously monitor up to 255 HSM2000 line monitoring device operation. Works HSM2000 dissolved gases in the transformer oil online monitoring system to continuously monitor the operation of the transformer oil content of hydrogen, carbon monoxide, acetylene, ethylene and other mixed gas, in order to achieve the purpose of detecting latent faults. First, the gas separation module to separate the dissolved gases in transformer oil. Then, the gas flows into the separated detection module, implemented by chemical signals to electrical signal transformation. Gas signal collected by the data acquisition module automatically calculates the concentration of the mixed gas depending on the gas calibration data. When the detected gas concentration exceeds the predetermined value or growth rate, the device automatically prompts alarm, easy next step transformer repair work. Gas detection communication flexibility to support wired and wireless communications, enabling more than one transformer on-line monitoring network. Configuring GSM SMS function, the user can grasp the first time through a mobile phone site testing data to achieve true unattended. Data Acquisition and gas separation strong anti-interference, stable performance device can meet harsh outdoor operating environment requirements, and can resist all kinds of electromagnetic fields substations, radio wave interference, the product passed the national quality inspection center electromagnetic compatibility testing. Fault diagnosis of transformer oil, easy maintenance and on-line chromatography class instruments were without regular replacement of the carrier gas and other consumables, without periodic calibration of the instrument installation HSM2000 line monitoring device is small, mounting flange and transformer through direct docking valve installation, without laying pipe between the device and the transformer tank. Installation Recommended installation position in POST3, transformer radiator circuit, the circulating pump outlet end; or mounted on POST1, POST2 such as transformer, the inlet valve, the lower position, the valve oil purifier, oil drain valve, etc. Cable laying line monitoring device field work required 220V 50Hz AC power (2A above) a pair; means such as the selection and substations background monitoring software wired communications, computer field from the back to the on-line monitoring devices need to lay a 2-core shielded communication cables. Technical parameters Power: 220V 50Hz AC power (2A above) degassing mode: polymer membrane degassing membrane life: more than eight years Measurement category: H 2, CO, C 2H 2, a mixed gas concentration C 2H 4 gas relative sensitivity : H 2: 100%, CO: 0.8%, C 2H 2: 0.2%, C 2H 4: 14% measuring range: 0 ~ 2000ppm detection principle: Imported Fuel Cell Sensor life: more than eight years Accuracy: ± 10% display : LCD monitor transformer oil temperature range: 15 ℃ ~ 80 ℃ Operating ambient temperature range: -40 ℃ ~ + 70 ℃ Storage temperature: -30 ℃ ~ + 75 ℃ Pressure: 0 ~ .2MPa Relative humidity: 5% to 95% , non-condensing Alarm output: background computer audible alarm; alarm output contacts both on the hardware data communication device: RS-485 / Ethernet wired / wireless (GPRS / CDMA / 3G) Optional communication distance: RS485 2000 meters, the field device and background monitoring system from the device size: 300 (L) × 280 (width) × 230 (H) mm unit Weight: 10KG Housing: IP65 protection class above
