Abstract
The utility model discloses an electric monitoring and protecting device, which comprises a motor digitization protector and a motor heat protector, wherein the motor digitization protector is mounted on a main power device, the motor heat protector is mounted on an auxiliary power device, the motor digitization protector is connected with a code converter through a wire, and the code converter is connected with a communication supervisor, and the communication supervisor is connected with a remote control device. The electric monitoring and protecting device has the advantages that the electric monitoring and protecting device can do remote monitor and protection to the power device, can reduce labor intensity, is convenient for finding hidden dangers in advance, and provides the reliability of power supply. The main power device remotely monitors, and the auxiliary power device controls on spot. The electric monitoring and protecting device reduces the operation, control and production cost of remote control, improves automatic level of monitor, has simple circuit allocation and sensitive protection, and can simultaneously monitor a great amount of power devices and the like.
Description
Technical field
The utility model relates to the electrical control field, specifically is a kind of electric monitoring protective device that can realize automatic remote monitoring.
Background technology
In process of production, for many years be the start and stop of field control power-equipment always, go from strength to strength that the distance of apparatus and operating room is more and more far away along with production-scale, simultaneously because the restriction of factors such as on-the-spot requirement of explosion proof, place restriction need be carried out remote monitoring to power-equipment.But existing long-distance monitorng device, its structure is often all very complicated, and circuit is loaded down with trivial details, is not suitable for large number quipments is monitored and remote monitor, and cost is high.
Summary of the invention
The utility model discloses a kind of electric monitoring protective device, it can solve the problem that exists in the known technology, and monitoring is monitored electric equipment automatically, and simple for structure, cost is low.
The utility model for achieving the above object; be achieved through the following technical solutions: a kind of electric monitoring protective device; comprise motor digital protection device and motor thermal protector; motor digital protection device is installed on the active force equipment; motor thermal protector is installed on the stand-by power equipment; motor digital protection device is connected with protocol converter by lead, and protocol converter is connected with communication manager, and communication manager is connected with remote control.
Advantage of the present utility model is: power-equipment is carried out the remote monitoring protection, can reduce labour intensity, be convenient to scent a hidden danger in advance, improve the reliability of power supply; The active force equipment remote monitoring, stand-by power equipment is controlled on the spot, has reduced the operation control and the cost of Long-distance Control, has improved the automatization level of monitoring; Line configuring is simple, and protection is sensitive, can monitor simultaneously a large amount of power-equipments etc.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is applicable to electric device is carried out the remote monitoring protection, is particularly useful for being equipped with the electric device of two cover power-equipments, comprises motor digital protection device 4 and motor thermal protector 6.Motor digital protection device 4 is installed on the active force equipment 5, and motor thermal protector 6 is installed on the stand-by power equipment 7.Motor digital protection device 4 described in the utility model, it is its low-voltage distribution control device based on arm processor hardware platform and embedded real-time operating system, can realize functions such as protection, control, communication, measurement, supervision, is furnished with data line ports, can realize transfer of data, be used for main power plant 5 is carried out monitoring and protection; Motor thermal protector 6 is not connected with remote control 1, directly realizes local control, is used for stand-by power unit 7 is carried out monitoring and protection, and its cost is low, and is simple for structure.Motor digital protection device 4 is connected with protocol converter 3 by lead.Protocol converter 3 is connected with communication manager 2, and communication manager 2 is connected with remote control 1.
In the utility model, when electric equipment is many, motor digital protection device 4 is installed on the active force equipment 5 of every electric equipment, motor thermal protector 6 is installed on the stand-by power equipment 7 of every electric equipment.Above motor digital protection device 4 is connected with protocol converter 3 by lead respectively, is connected with remote control 1 through communication manager 2 again.When motor thermal protector 6 numbers greater than 20 the time, in order to improve the transmission speed of signal, a plurality of protocol converters 3 of operated by rotary motion, each protocol converter 3 is connected with communication manager 2 by lead respectively.
Set up electromagnetic interference, the prolongation monitoring distance of bringing for reducing with power cable with crane span structure, 1 of communication manager 2 and remote control adopt the optical-fibre communications transmission.
When the utility model uses; motor digital protection device 4 is delivered to protocol converter 3 with monitored results; after 3 pairs of communications protocol of protocol converter are changed, import signal into communication manager 2 in the mode of Ethernet, finally be delivered on the remote control 1.
