Power distribution cabinet refers to the equipment of the distribution systems such as dynamic power distribution cabinet, light distribution cabinet and metering cabinet, in actual life, when power distribution cabinet ground connection is bad, Housing failure, electrical equipment make moist, aging circuit time, easy initiation leaky and short circuit phenomenon, not only can affect resident's normal electricity consumption, and hold the accident such as fire hazardous, human electric shock, cause a series of harm.In prior art; user power utilization safety can be improved to a certain extent by installing earth leakage protective device in power distribution cabinet; but the automaticity of fault centralized monitor is low; when there is the faults such as electric leakage or electric shock; administrative staff can not find the power distribution cabinet specifically broken down immediately; cause maintenance time delay, can not select selectively to have a power failure so that the region of maintenance, cause the inconvenience of residential electricity consumption.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of power distribution cabinet based on CAN formula electric leakage monitoring and guard system, can arrange identification code to the power distribution cabinet in region, the ruuning situation of convenient record and monitoring power distribution cabinet, once there is the situations such as electric leakage, can overhaul in time.
The technical solution adopted in the utility model is: a kind of electric leakage of the power distribution cabinet based on CAN formula monitoring and guard system, it is characterized in that: comprise and be somely arranged at the power distribution cabinet earth detector of single power distribution cabinet, the CAN be connected with power distribution cabinet earth detector and the center of the centralized monitor for remote monitoring respectively, each CAN is connected to center of the centralized monitor by CAN;
Wherein, described power distribution cabinet earth detector comprises circuit breaker, current transformer, temperature sensor, voltage detector, over-current detector, processor module, control relay and release, one end of described circuit breaker connects electrical network input, the other end is connected to user load end by current transformer, the output of current transformer connects voltage detector and over-current detector respectively, described voltage detector, over-current detector and temperature sensor are connected to processor module, the output connection control relay of processor module, control relay is through release connecting breaker,
Described center of the centralized monitor arranges display screen and alarm.Display screen can demonstrate the power distribution cabinet that the abnormal conditions such as electric leakage occur intuitively, and the leakage current of power distribution cabinet, voltage and ambient temperature value etc., and alarm plays the effect of prompting staff, avoids delaying repairing opportunity.
Particularly, described CAN comprises controller that model is MCP2515 and model is the transceiver of TJAI050.MCP2515 controller mainly completes the work such as sequential logic conversion, reliably easy to connect between itself and processor, TJAI050 transceiver is one can realize conversion chip, the electrical characteristic of signal can be made to meet CAN standard, in consolidated network, allow the multiple node of mounting, be convenient to the network management of system.
Operation principle of the present utility model is described below: in power distribution cabinet, and the input of electrical network flows into user load end through circuit breaker summation current transformer.When user load end occurs that abnormal conditions are got an electric shock as electric leakage or personnel, current transformer can detect the unsymmetrical current on the circuit that produces because of abnormal conditions, send after concrete abnormal voltage value and current value check processing into processor module through voltage detector and over-current detector simultaneously, temperature sensor detects the ambient temperature in power distribution cabinet and sends temperature value to processor module, processor module is to the magnitude of voltage received, current value and temperature value and the value preset compare, analyze, after determining that abnormal conditions exist, namely this processor module transmits control signal to control relay, and then drive release to open, circuit breaker disconnects, cut off the power supply of this supply line to user load.Processor module simultaneously by abnormal conditions signal transmission to CAN, CAN sends signal to centralized-control center through CAN, the staff of centralized-control center judges the power distribution cabinet of generation leaky according to the information received and takes solution, efficient quick.
Owing to have employed technique scheme, the utility model has following technique effect: the utility model adopts CAN formula to realize the transfer of data of multiple power distribution cabinet drain conditions, and CAN is the fieldbus having formed international standard, there is high, the easy realization of traffic rate, cost performance high.The electric leakage being convenient to centralized monitor power distribution cabinet is monitored and is protected, malfunction elimination efficiency is high, and can not affect the normal work of other power distribution cabinet.
