Description

Wiring device suitable for industrial application miniature motor Technical Field The utility model relates to the technical field of motor wiring, in particular to a wiring device suitable for industrial application of a small miniature motor. Background In industrial enterprises, small micro-motors of less than 2.2kW are widely used for transmission of various main operations or auxiliary equipment, such as small centrifugal pumps, metering pumps, dosing pumps, lubrication pumps, ventilation fans, etc. Because of the complex environment of the industrial production site, corrosive gas, corrosive dust, high temperature, high humidity, vibration during the running of equipment, vibration or resonance caused by the running of other equipment on the site, and the like, the method has higher requirements on the reliability and convenience of the wiring of the motor, and has great difficulty in the wiring of the equipment due to the small space of some parts. Moreover, because the power transformation and distribution facilities of some medium-sized and large-sized industrial enterprises are concentrated, the power supply distance of electric equipment is more than 100 meters, even more, the section of a power supply cable of a small miniature motor with the power supply of 2.2kW and below which needs to be independently supplied and controlled in a production field is generally not lower than ZA-YJV 22.6/1 kV 4×2.5mm 2, and the small miniature motor with the power level of 2.2kW and below is usually a traditional wiring mode of wiring terminals and through bolt crimping, the internal body winding of a motor junction box is led out to be a thinner annealed copper wire, and at present, the common wiring mode of the small miniature motor has a plurality of problems: 1. The traditional wiring mode is complex and inconvenient to install, in an industrial production field, the wiring of the small miniature motor is difficult to operate by fastening bolts, professional tools and skilled technicians are required to operate, and even the personnel may need to finish wiring operation in a narrow space, so that wiring cannot be performed or the time is long. 2. The connection reliability is poor, vibration and temperature change in industrial field environment and possible chemical corrosion are easy to cause loosening and oxidation of the connection part of the traditional bolt crimping connection mode, the conductivity is reduced, and even abnormal intermittent operation, phase failure operation and the like of the motor are caused. 3. The safety is insufficient, and the special nature of the industrial environment requires better insulation and protection performance of the motor wiring. After the traditional wiring mode is used for a long time, the on-site vibration easily causes loosening of the crimping bolts and loosening of the wiring, so that accidents such as ground faults and interphase short circuits are caused, and the safety and the production stability of personnel are threatened. 4. For motors with the power supply distance of more than 100 meters and needing to be powered by ZA-YJV 22.6/1 kV 4 multiplied by 2.5mm 2 cable lines, wiring modes of wiring terminals phi 6 and below bolt crimping adopted by small miniature motors with the power levels of 2.2kW and below are adopted, single-core hard wires are adopted in the cables, multi-core soft wires are adopted in motor winding outgoing lines, and virtual connection is easily caused by soft and hard wire crimping and connection during internal and external wiring. Therefore, a reliable wiring structure suitable for industrial applications, particularly for small micro motors of industrial enterprises of 2.2kW and below, is needed to realize rapid and convenient wiring operation, improve the reliability and safety of wiring, and is easy to overhaul, thereby meeting the use requirements under complex environments of industrial applications.
