Abstract
An intelligent motor protector comprises a motor body. The lower portion of the motor body is fixedly connected with a support, and the top end of the motor body is fixedly connected with a protector. The intelligent motor protector has the advantages that the top end of the motor body is connected with the protector, so that the protector can effectively protect a motor and prevent the motor from damaging.
Description
Technical field
The present invention relates to a kind of electric motor protective device, relate in particular to a kind of intelligent protector for motor.
Background technology
Low-tension motor size in my power plant's electricity generation system has more than 300 approximately, and former design all adopts old-fashioned thermal relay to protect.Because malfunction, tripping often appear in old-fashioned thermal relay, can't ascertain the reason again, bring great hidden danger for power plant safety stable operation.
Summary of the invention
The intelligent protector for motor that the purpose of this invention is to provide a kind of automatic protection motor.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of intelligent protector for motor, comprising: the motor main body, motor main body below is fixedly connected with support, and its characteristics are: the top of described motor main body is connected with protector.
Advantage of the present invention is: the top of motor main body of the present invention is connected with protector, and protector is effectively protected motor, prevents that motor from damaging.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the accompanying drawing
1, support; 2, motor main body; 3, protector.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
A kind of intelligent protector for motor, as shown in Figure 1, comprising: motor main body 2, motor main body 2 belows are fixedly connected with support 1, and the top of described motor main body 2 is connected with protector 3.
Beneficial effect of the present invention:
1, by the Real-Time Monitoring to the three-phase current of motor, three-phase voltage, leakage current, contactor state, realizes the perfect protection to motor.Various defencive functions are separate, and multi-protective function might trigger simultaneously, but only have the defencive function that reaches at first the dropout condition to send the order of threading off.
2, defencive function have thermal overload, mutually imbalance, phase shortage, under-voltage, underloading, stall, startup is overtime, rolling is electric (power-down rebooting).
3, all defencive functions all can arrange instrument by host computer or scene and arrange, start or close according to actual conditions, adjust the protection value.
4, control function: across-the-line starting, directly bypass starting, rotating-across-the-line starting, rotating-bypass starting, the starting of star triangle, Auto-start relief transformer, soft initiator control, in many ways starting control, process concatenation control, the input and output of programmable switch amount, 4~20mA analog output.
5, show monitoring: three-phase current, three-phase voltage, leakage current, apparent power, active power, power factor, electricity, thermal capacity, running status, fault message, the number of starts, running time.
6, fieldbus function: this motor protector has two RS-485 remote communication interface, supports MODBUS-RTU, PROFIBUS-DP agreement to be equipped with simultaneously 4~20mA analog output, easily with PLC, DCS and background computer network consisting system.
The top of motor main body of the present invention is connected with protector, and protector is effectively protected motor, prevents that motor from damaging.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and protection range are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
Claims (1)
1. intelligent protector for motor, comprising: motor main body (2), motor main body (2) below is fixedly connected with support (1), and it is characterized in that: the top of described motor main body (2) is connected with protector (3).
