Abstract
The utility model relates to an automatic current control device which comprises an isolated fuse switch (RT), a leakage switch (K), an alternating current contactor (F) and a current relay (JL) which are connected in a main circuit transmission line in series in sequence. A plurality of electric loads connected in parallel are also included in a main circuit; the current relay (JL) comprises a JL normally closed contact and a JL normally opened contact; the current relay (JL) is connected with an electronic time relay (JS) in series; and the JL normally closed contact and the JL normally opened contact are respectively connected with the delayed actuation (JS1) of the electronic time relay (JS) and the delayed disconnection (JS2) of the electronic time relay (JS) in series. In the utility model, the power-on and the power-off of an electric line can be controlled according to the current intensity; and the circuit is power off by using the time relay to achieve the effect of automatically recovering power supply after the setting time is achieved. The utility model has the advantages of simple manufacturing process, low cost and large control capacity and can be used for current control in living quarters and dormitories in construction fields.
Description
Technical field
The utility model relates to circuit control field, relates in particular to a kind of automatic current control device.
Background technology
Because living area, construction site personnel live in concentrated communities more, and quality of workers is not high, high-power electrical equipment violating the regulations uses frequent, these high-power electric appliances are generally manufactured in a rough and slipshod way, potential safety hazard is more, increased hidden fire-fighting danger greatly on the one hand, also caused the waste of the energy on the other hand, disagreed with the theory of the current wound conservation-minded society that advocates.Though the current controller that uses on the current market also has the effect by the Current Control break-make, but its electric current all cannot be regulated recovery time, Control current is little simultaneously, and the control capacity is not suitable for the overall control of the more situations of personnel such as living area, building site at 300～500w.For this reason, invention design a kind of can regulate electric current automatic recovery time and control current controller capacious by the time relay necessitate.
The utility model content
The purpose of this utility model provides a kind of automatic current control device, and is unadjustable recovery time to overcome existing current controller electric current, the deficiency that Control current is little, the control capacity is little simultaneously.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of automatic current control device, comprise the isolated fuse cutout (RT) that is serially connected in successively in the main circuit transmission line, leakage switch (K), A.C. contactor (J), current relay (JL), the electric loading of using that also comprises some parallel connections in the main circuit, current relay (JL) comprises JL normally-closed contact and JL normally opened contact, current relay (JL) is connected in series with electronical time relay (JS), and wherein JL normally-closed contact and JL normally opened contact are connected in series with electronical time relay (JS) time-delay adhesive (JS1) and electronical time relay (JS) time-delay disconnection (JS2) respectively.
The beneficial effects of the utility model are: can be according to size of current control break-makes with electric line, and the use by the time relay simultaneously reaches circuit and disconnects the effect that reaches automatic recovery of power supply after the time of setting; Preparation technology is simple, and is with low cost; The control capacity is big, can be used for the Current Control in dormitories such as living area, construction site.
Description of drawings
Fig. 1 is the schematic diagram of the main circuit of the described automatic current control device of the utility model embodiment;
Fig. 2 is the automatic current control device automatic current control circuit schematic diagram of the utility model embodiment.
Among the figure:
1, isolated fuse cutout (RT); 2, leakage switch (K); 3, A.C. contactor (J); 4, current relay (JL); 5, with electric loading (socket); 6, JL normally-closed contact; 7, JL normally opened contact; 8, electronical time relay (JS) time-delay adhesive (JS1); 9, electronical time relay (JS) time-delay disconnects (JS2).
Embodiment
Shown in Fig. 1-2, the described a kind of automatic current control device of the utility model embodiment, comprise the isolated fuse cutout (RT) 1 that is serially connected in successively in the main circuit transmission line, leakage switch (K) 2, A.C. contactor (J) 3, current relay (JL) 4, the usefulness electric loading (socket) 5 that also comprises some parallel connections in the main circuit, current relay (JL) 4 comprises JL normally-closed contact 6 and JL normally opened contact 7, current relay (JL) 4 is connected in series with electronical time relay (JS), and wherein JL normally-closed contact 6 and JL normally opened contact 7 are connected in series with electronical time relay (JS) time-delay adhesive (JS1) 8 and electronical time relay (JS) time-delay disconnection (JS2) 9 respectively.
In the described automatic current control device of the utility model embodiment, electronical time relay is selected the DHC2-2 model for use; Current relay is selected JL15 series for use, selects according to the Control current needs; A.C. contactor is selected the JX2 serial model No. for use; Isolated fuse cutout is selected RT18 series for use; Leakage switch is selected DZ47L series for use.
The operating process of automatic current control device described in the utility model is as follows: when normally starting, JS1 energising back closure → J energising → J self-locking power supply → main circuit is connected, at this moment the circuit normal power supply.Under the overload situations, JL moves, the adhesive of JL normally opened contact, and JS2 disconnects (delaying time 15 seconds), causes the J outage, and main circuit disconnects.Simultaneously, the JL normally-closed contact disconnects, JS1 energising, and the adhesive in 30 minutes of delaying time (time is adjustable, 1 minute～30 minutes).This section is in off-position always in the period.When reaching delay time, the JS1 adhesive, after the J energising, main circuit will recover the self-locking power supply, and this moment, circuit recovered normally.Thereby reach the break-make by the size of current control loop and disconnect after restore electricity the voluntarily control of time.Many circuit control gets final product according to above circuit theory increase.According to circuit diagram shown in Figure 2 electronic time relay and current relay are assembled, be series in the main circuit, can reach the effectiveness of control circuit.
