Description
Technical field
The utility model relates to protective device field, particularly relates to a kind of motor protection control device.
Background technology
Motor protection control device is the failure diagnosis and the intelligent motor protective device developed that produce in various application scenario for low-tension motor.It is little that it has volume, and lightweight, powerful, reliability is high, flexible configuration, good looking appearance, the feature such as easy for installation.The high speed processor of high integrated system is adopted to carry out data sampling and processing; on the basis realizing traditional low-tension motor protection; incorporate observing and controlling, metering, log and communication function; really realize digitlization; intelligent; networking, accomplish protection and measurement and control and one, the management controlled for industrial processes brings great convenience.Existing motor protection control device can not well be protected the harm that the overload of motor, short circuit, ultra-long time startup, stall, imbalance, the fault such as under-voltage cause.
Utility model content
Problem to be solved in the utility model is: provide a kind of motor protection control device, and the harm that its overload to motor, short circuit, ultra-long time startup, stall, imbalance, the fault such as under-voltage cause is protected.
The utility model technical solution problem adopts following technical scheme:
A kind of motor protection control device; comprise protective device; described protective device is provided with one group of voltage input end, one group of leakage current, one group of analog output, a group communication interface, one group of control output end, one group of remote control terminal; described control output end comprises parking output protection and exports, starts output, overflow fault and warning output, and described voltage input end voltage is lower than 690V.
Preferably, described communication interface is the RS-485 communication interface of standard, and it adopts MODBUS-RTU communications protocol, and described communication interface easily can realize the distant place management of data.
The beneficial effects of the utility model are: the utility model compares traditional motor protection control device, can be good at being protected to the harm that the overload of motor, short circuit, ultra-long time startup, stall, imbalance, the fault such as under-voltage cause.
Accompanying drawing explanation
