Current transformer; 8. Vibration sensor; 9. DC power supply; and 10. Host computer. Detailed Implementation
[0026] The following is in conjunction with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0027] Example 1
[0028] Reference Figure 1 A status monitoring system for station electromechanical equipment includes a controller 1, an analog input module 2, a temperature signal transmitter 3, a temperature sensor 4, a magnetic temperature sensor 5, a multi-function energy meter 6, and a current transformer 7.
[0029] Reference Figure 1 and 3 Temperature sensor 4 and magnetic temperature sensor 5 are connected to controller 1 via temperature signal transmitter 3 and analog input module 2, respectively; while current transformer 7 is connected to controller via multi-function energy meter 6.
[0030] Since most of the heavy-load electromechanical equipment in the station, such as central air conditioning fans, motors, and water pumps, are in a concealed or semi-concealed state, manual inspection cannot effectively detect abnormal conditions of the electromechanical equipment, nor can it easily detect the various operating parameters of the electromechanical equipment.
[0031] Therefore, in this embodiment, the temperature sensor 4 is installed on the cable on the power switch input / output side of the electromechanical equipment and fixed by binding. By acquiring the temperature of the cable, it is equivalent to acquiring the temperature data at the power switch of the electromechanical equipment. This setup allows the system to detect whether the power switch of the electromechanical equipment will overheat due to sudden changes in starting current or three-phase imbalance when the equipment is turned on, thereby detecting any abnormal conditions in the motor. The temperature sensor 4 is a PT100 type temperature sensor.
[0032] In this embodiment, a magnetic temperature sensor 5 is also attached to the bearing of the electromechanical equipment to obtain the bearing temperature. By using the magnetic temperature sensor 5, the sensor can be effectively fixed to the bearing of the electromechanical equipment, preventing it from falling off. Furthermore, based on the temperature data obtained by the magnetic temperature sensor 5, it is possible to promptly detect abnormal bearing heating caused by bearing aging, overdue operation, or other problems, and also to detect any abnormal conditions in the electromechanical equipment. The magnetic temperature sensor 5 is a PT100 type magnetic temperature sensor.
[0033] By adopting the above settings and combining different types of temperature sensors with the structural characteristics of the electromechanical equipment, temperature data at different locations of the electromechanical equipment can be effectively obtained. At the same time, the different types of temperature sensors used are also compatible with the environment in which the electromechanical equipment is located, thus facilitating the installation of various components.
[0034] The temperature sensor 4 and the magnetic temperature sensor 5 are connected to the controller 1 in sequence through the temperature signal transmitter 3 and the analog input module 2.
[0035] In this embodiment, the temperature signal transmitter 3 is a TS-TR-5P11 type temperature signal transmitter, used to convert the data acquired by the temperature sensor 4 and the magnetic temperature sensor 5 into a 4-20mA signal, which is then input into the controller 1 through the analog input module 2, thereby enabling the monitoring of the operating status information of the electromechanical equipment. The controller 1 is a DVP-12SE type controller, which is small in size and easy to install; while the analog input module 2 is a DVP-04AD type analog input module.
[0036] Reference Figure 1 The current transformer 7 is installed on the load cable of the electromechanical equipment by a snap-fit, and is used to obtain the operating current of the electromechanical equipment. At the same time, the current transformer 7 is connected to the controller 1 through the multi-function energy meter 6 and transmits the obtained data to the controller 1.
[0037] In this embodiment, the current transformer 7 is a ZDKCT36M / 100 / 5 type current transformer. By acquiring the operating current of the electromechanical equipment, it is possible to detect whether there is an abnormal operating state of the electromechanical equipment caused by a sudden increase in current draw due to high-order harmonics.
[0038] Meanwhile, the multi-functional energy meter 6 is a DTS / DDSV1.3 type energy meter, which can obtain the current and voltage data during the operation of electromechanical equipment based on the current data obtained by the current transformer 7. Based on the obtained voltage and current, it can detect whether the electromechanical equipment will have abnormal conditions such as phase loss, overcurrent and power supply voltage drop.
[0039] Reference Figure 1 The condition monitoring system also includes a vibration sensor 8.
[0040] The vibration sensor 8 is installed on the motor housing and base of the electromechanical equipment to obtain the vibration frequency of the electromechanical equipment.
[0041] In this embodiment, the vibration sensor 8 is a CRZ-401 type vibration sensor, which has strong magnetism and can be fixedly attached to the motor housing and base of the electromechanical equipment. By acquiring the vibration parameters of the motor housing and base of the electromechanical equipment, it is possible to detect whether the electromechanical equipment is damaged or the mechanical parts are faulty due to the loosening of the equipment base or mounting bolts.
[0042] Meanwhile, the vibration sensor 8 is connected to the controller 1 through the analog input module 2 and transmits the acquired monitoring data to the controller 1.
[0043] This embodiment utilizes various sensors and the acquired parameter data to detect potential safety hazards or malfunctions in electromechanical equipment in real time, thereby achieving real-time monitoring of the equipment in the station. Based on the monitored data, the equipment can be repaired in advance to ensure the normal operation of the station.
[0044] Reference Figure 1-2 The status monitoring system also includes a DC power supply 9 and a host computer 10.
[0045] Among them, the DC power supply 9 can be an EDR-75-24 type power supply, which provides power to the controller 1, analog input module 2, temperature signal transmitter 3 and various sensors, ensuring the normal operation of the devices; while the host computer 10 is connected to the controller 1.
[0046] In this embodiment, the host computer 10 has functions such as LCD display, wireless transmission and communication; the controller 1 transmits the acquired parameters to the host computer 10, the host computer 10 displays the monitoring data, and when an abnormal state of the electromechanical equipment is detected, it can remind the user through alarms and other means, so as to repair the abnormal electromechanical equipment.
[0047] The functions of the host computer 10 can be adaptively adjusted; meanwhile, various devices such as sensors, temperature signal transmitters 3, and multi-function energy meters 6 communicate with each other via ZR-KVVP. Multi-core shielded control cables are used for connection and data transmission; the number of each sensor is matched with the number of electromechanical equipment in the station.
[0048] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
