Description

Technical Field

[0001] This utility model relates to the field of circuit and motor fault monitoring technology, and in particular to a circuit and motor fault monitoring instrument. Background Technology

[0002] In mining production, circuits and equipment require regular maintenance after prolonged operation. Delayed or inaccurate maintenance can lead to equipment wear and tear, increase the probability of malfunctions, reduce lifespan, and even endanger the lives of underground workers. Typically, there are warning signs before equipment malfunctions, such as changes in operating parameters indicating that the equipment's condition is not ideal. Timely intervention and inspection at these points can detect problems early and reduce the risk of downtime.

[0003] However, currently, most mining monitoring relies on electrical indicators such as motor current and frequency to assess circuits and motors. But often, by the time these indicators change significantly, it's too late to take action, missing the optimal maintenance window. Furthermore, many faults may not occur with significant changes in electrical parameters, meaning maintenance personnel may only discover the problem after it has happened, by which time corrective action has already disrupted normal mining operations. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a circuit motor fault monitoring instrument, the purpose of which is to solve the problems mentioned in the background art.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A circuit motor fault monitoring instrument includes motor wires, motor, coupler, VTM3160 sensor, insulation monitor, LED touch screen, HZ-158 gateway, HZ193 meter and 4G antenna;

[0007] A coupler is installed between the insulation monitoring instrument and the motor wires;

[0008] The HZ193 instrument is connected to the motor wires;

[0009] The insulation monitoring instrument is interlocked with the auxiliary contacts of the motor circuit contactor or circuit breaker for control.

[0010] A VTM3160 sensor is fixedly mounted on the motor.

[0011] The insulation monitor is connected to the LED touch screen via an RS485 communication interface.

[0012] The LED touchscreen, VTM3160 sensor, and HZ193 instrument are connected to the HZ-158 gateway via RS485 communication interfaces.

[0013] Furthermore, the insulation monitoring instrument is used to disconnect from the power grid when the motor circuit is energized.

[0014] Furthermore, the coupler is used for the protection of the line and the main unit of the insulation monitoring instrument.

[0015] Furthermore, the HZ193 instrument is used for power quality monitoring, leakage current or zero-sequence current monitoring, temperature measurement, fault arc detection, fault early warning, fault recording, and monitoring of three-phase voltage, current, frequency, power, power factor, and electricity consumption of conventional power equipment.

[0016] Furthermore, the VTM3160 sensor is used to measure the vibration velocity and acceleration of an object in three mutually perpendicular axes, as well as its surface temperature, to monitor its vibration and temperature status.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model discloses a circuit motor fault monitoring instrument. By integrating a VTM3160 sensor, the insulation monitoring instrument can monitor the insulation status of the motor circuit in real time, ensuring safe operation of the equipment. When the insulation monitoring instrument detects an abnormality, it can issue an alarm in time to avoid accidents. The insulation monitoring instrument, VTM3160 sensor, and LED touch screen can exchange data with other devices through an RS485 communication interface, realizing the monitoring of multiple aspects such as power quality, leakage current, zero-sequence current, temperature, and fault arc, improving the safety and economy of equipment operation. Through the onboard monitoring module, the instrument has fault early warning and fault recording functions, which can monitor the operating status of the equipment in real time. The insulation monitoring instrument can exit monitoring and disconnect from the power grid when the motor circuit is energized, avoiding unnecessary human intervention and thus saving energy consumption. By protecting the circuit and the main unit of the insulation monitoring instrument, the risk of equipment damage is reduced and the equipment life is extended. The integration of multiple functional modules reduces equipment downtime and improves production efficiency. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the circuit motor fault monitoring instrument of this utility model; Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1As shown, a circuit motor fault monitoring instrument is disclosed. The insulation monitoring instrument uses the DC high voltage injection method to measure the insulation of cables or motor windings, etc. The test voltage is DC2500V. It includes motor wires, motor, coupler, VTM3160 sensor, insulation monitoring instrument, LED touch screen, HZ-158 gateway, HZ193 instrument and 4G antenna.

[0022] The insulation monitor is interlocked with the auxiliary contacts of the motor circuit contactor or circuit breaker to realize that the insulation monitor stops monitoring and is separated from the power grid when the motor circuit is energized, and automatically starts monitoring the insulation of the line when the line is de-energized. Although the insulation monitor only monitors after the bus is de-energized, it is also equipped with a coupler to protect the line and the main unit of the insulation monitor, considering that it is directly connected to the high-voltage bus.

[0023] The HZ193 device receives a 100V voltage input via a voltage transformer (PT) and, through its core algorithm, performs functions such as power quality monitoring, leakage current or zero-sequence current monitoring, temperature measurement, fault arc detection, fault early warning, and fault recording. It can also monitor the three-phase voltage, current, frequency, power, power factor, and electricity consumption of conventional power equipment.

[0024] The VTM3160 sensor analyzes the vibration and temperature state of an object by measuring its vibration velocity and acceleration along three mutually perpendicular axes, as well as its surface temperature.

[0025] Finally, the data is transmitted via RS485 communication interface to the monitoring system for overall analysis of each parameter.

[0026] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
