Description
Affiliated technical field
The utility model belongs to electric power identification and control field, especially has the pernicious load Intelligent Recognition device of resistive load, capacitive load, inductive load identification and automatic controlled function.
Background technology
At present, dormitory in most of institutional settings or factory of universities and colleges, generally be to adopt artificial or administrative means to using high-power electric appliance and easily ignitablely being resistive pernicious load and managing and forbid, but this management means efficient is too low, very limited to using high-power electric appliance and being the control and the management of resistive pernicious load, cause the significant wastage and the line security hidden danger of electric power.
Summary of the invention
Be conservation of power resource better, avoid the manpower waste, control high-power electric appliance more effectively and be the use of resistive pernicious load, realize whole day management automatically in 24 hours, the utility model provides a kind of pernicious load Intelligent Recognition device, this pernicious load Intelligent Recognition device is with being connected with electric line of wanting to control and after the limited power value is set, can be to the load gross power of using on the electric line be resistive pernicious bearing power and discern and control; When the user attempts to use the resistive load of the resistive limit value that surpasses setting, the pernicious load Intelligent Recognition device that connects disconnects the user power utilization circuit automatically, when its gross power of electrical equipment of user's use surpassed the gross power limit value of setting, the pernicious load Intelligent Recognition device that connects also disconnected the user power utilization circuit automatically; Pernicious load Intelligent Recognition device cuts off the power supply automatically can connect automatically in back 25 to 35 seconds and uses electric line, discern next time, pernicious load Intelligent Recognition device is provided with limit value outage automatically because of surpassing with electric line, every outage is automatically once counted once, to connecting subscribers participating electric line no longer automatically after adding up three times, use electric line and can only realize connecting by hand-reset, pernicious load Intelligent Recognition is thought highly of and is newly begun to count after the hand-reset.This pernicious load Intelligent Recognition device takes up room little, easy for installation, simple to operate, in universities and colleges and residential block or group company all can unify to install; Pernicious load Intelligent Recognition device be connected with electric line and be provided with after, only when being set, power limit cuts off the power supply surpassing, in being set, power limit make electrical appliance unaffected, the outage back can recover to send in 25 to 35 seconds automatically, need not staff on duty, the real whole day that realizes was discerned and control in 24 hours automatically, had saved the great amount of manpower resource; And surpass power limit and the accumulative total of cutting off the power supply must could be recovered user power utilization by manual reset after three times, make things convenient for the manager effectively to manage.
The technical scheme that its technical problem that solves the utility model adopts is:
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a theory diagram of the present utility model.
Be the coupling part, inside of pernicious load Intelligent Recognition device in the dashed rectangle among Fig. 1.
Embodiment
Described pernicious load Intelligent Recognition device is followed before dispatching from the factory according to needs and is carried out setting of gross power limit value and the setting of resistive load limit value.Described pernicious load Intelligent Recognition device is that its zero line side is connected on the zero line of 220 volts of AC network, and the live wire input is connected on the live wire of 220 volts of AC network, and the usefulness electric line live wire that will want again to control is serially connected on the live wire output.Described pernicious load Intelligent Recognition device is after 220 volts of grid ac voltages introducing power units are done step-down and voltage stabilizing processing, to be transported to inner each circuit part respectively; Described pernicious load Intelligent Recognition device and outside electric power network system connect the back operate as normal, and the operate as normal initial stage is carried out initial reset by reset circuit one time to counting circuit; Waveform shaping circuit inner after the operate as normal carries out the square wave shaping, again the square wave after the shaping is delivered to integrating circuit; The usefulness electric line live wire that will be connected automatically by control circuit after the described pernicious load identifier operate as normal is switched to the live wire of electrical network, by sample circuit the access bearing power with electric line is carried out real-time sampling after the operate as normal, the signal of sampling is delivered to amplifying circuit and is carried out the signal amplification, amplifying signal is delivered to integrating circuit after by the limit value regulating circuit, after the square wave that integrating circuit is sent amplifying signal and waveform shaping circuit here is discerned and is calculated, delivering to comparison circuit compares, result relatively is connected to circuits for triggering, circuits for triggering are followed according to comparative result and are removed trigger control circuit and counting circuit, select whether to disconnect the user power utilization circuit that is connected by counting circuit with control circuit.When the sample circuit of described pernicious load identifier sample with electric line on total load or when being resistive pernicious load and surpassing the power limit that is provided with, comparison circuit will be exported corresponding signal and remove trigger control circuit and counting circuit, by control circuit disconnect user circuit; Counting circuit is counted the triggering signal of open-circuit line behind described pernicious load Intelligent Recognition device disconnect user circuit, if this moment, counting circuit accumulative total did not reach 3 times, then counting circuit is not exported any signal, if counting accumulative total reaches 3 times, then counting circuit outputs signal to control circuit, makes no longer connecting subscribers participating circuit of control circuit; In the disconnect user circuit, its circuits for triggering are started the clock, when power-off time reaches about 30 seconds, send the triggering signal of connecting circuit to control circuit once more, and described pernicious load Intelligent Recognition device only when the counting circuit no signal is exported its control circuit could connect the subscriber's line of being controlled.Limit value regulating circuit among Fig. 1 can be regulated, and makes it reach automatic disconnection electric line when specifying the power limit that is provided with, and then reaches the automatic control that discern and control subscriber's line is switched on and off.Reset circuit among Fig. 1 once resets to counting circuit after energising automatically, thereby numerical value zero clearing with counting circuit, can only be in the energising course of work by the zero clearing that manually resets, reach 3 times, control circuit no longer during the connecting subscribers participating circuit in counting circuit counting accumulative total, the manager can carry out hand-reset by reset circuit.
