Abstract

The utility model relates to a current controller, which comprises a casing, an electromagnetic inductor, a movable armature, a magnetic coil, a return spring, an adjusting tension spring, a time-delay power-off device, a main control spring plate contact terminal, an assistant spring plate contact terminal, an assistant spring plate contact terminal close spring and the like. The current controller is installed on a phase line, and the control circuit of the current controller adopts series connection. The current controller can be directly used by matching with a magnetic starting switch at small load, and can be used in conjunction with a current transformer and the magnetic starting switch at large load. The current controller can be used for high voltage, low voltage, alternating current, direct current, large load, small load and the like and also used for over current, fire touch, loss phase, loose contact, over-high voltage or over-low voltage and the like, can be cut off automatically, and has the advantages of complete functions, high sensitivity and low manufacturing cost.

Description

Current controller

Technical field

The utility model relates to a kind of Protector for using electricity, particularly a kind of current controller.

Background technology

Present current controller is a lot, but full complex structure, the cost height of function, and general controller is pressed with requirement to alternating current-direct current, height, the electricity consumption size can not regulated at will.

Summary of the invention

The purpose of this utility model provides a kind of current controller of scalable electricity consumption size.

The utility model is made up of shell and electromagnetic inductor, mobile armature, return spring, adjusting extension spring, delay cut-off device, master control shell fragment contact, auxiliary shell fragment contact, auxiliary shell fragment contact closure spring etc.Electromagnetic inductor is fixed on the shell, and mobile armature one end is hinged on the electromagnetic inductor, and tail end is connected with one and regulates extension spring, and the insulation board that is fixed on the tail end withstands on the auxiliary shell fragment, and the closure of auxiliary shell fragment contact is by closing spring and mobile armature control; On mobile armature flared end and master control shell fragment contact correspondence position, also be fixed with an insulation board, be used to back down master control shell fragment contact, have a lead to be connected between master control shell fragment contact and auxiliary shell fragment contact; Be connected with a delay cut-off device at auxiliary shell fragment contact two ends, this delay cut-off device is by thermistor, hot directional deformation paillon foil and decide contact blade and form.

Current controller of the present utility model is installed on the phase line, and its control circuit is connected.Little load is joined magnetic starting switch and is directly used, and big load needs distribution current transformer and magnetic starting switch to use together.It can be used for generation overcurrents such as high pressure, low pressure, interchange, direct current, size load, bump fire, fall phase, loose contact, overtension or low excessively etc., all can cut off the power supply automatically, and perfect in shape and function, highly sensitive, and cheap.

Specific embodiments

As shown in the figure, electromagnetic inductor (2) is fixed on the shell (1), mobile armature (3) one ends are hinged on the electromagnetic inductor (2), mobile armature (3) tail end is connected with one and regulates extension spring (5), the auxiliary shell fragment contact insulation board (14) that backs down that is fixed on mobile armature (3) tail end withstands on the auxiliary shell fragment (9), and the closure of auxiliary shell fragment contact (10) is by auxiliary shell fragment contact closure spring (11) and mobile armature (3) control; On mobile armature (3) flared end and master control shell fragment (7) correspondence position, be fixed with one and back down master control shell fragment contact insulation board (13), be used to back down master control shell fragment contact (8), have one to be connected lead (12) and to link to each other between master control shell fragment contact (8) and auxiliary shell fragment contact (10); Be connected with a delay cut-off device (6) at auxiliary shell fragment contact (10) two ends, this delay cut-off device (6) is by thermistor (15), hot directional deformation paillon foil (16) and decide contact blade (17) and form.

During use, press starting button, master control shell fragment contact (8) closure, electrical equipment or circuit are started working, but the high electric current of moment of starting can will assist shell fragment contact (10) to disconnect, at this moment just continue to power to electromagnetic inductor (2) by delay cut-off device (6), after moment, high electric current lowered, mobile armature (3) was conditioned extension spring (5) and return spring (4) top return, and auxiliary shell fragment contact (10) is return also, connect control circuit, electrical equipment or circuit just enter normal operation.When electrical equipment or circuit generation overcurrent, loose contact, overtension, brownout, the electric current of electrical equipment or circuit increases, the pulling force that has surpassed adjusting extension spring (5), mobile armature (3) will be inhaled by the magnetic force of electromagnetic inductor (2) and closely contact with return spring (4), the auxiliary shell fragment contact (10) of mobile armature (3) tail end disconnects, but at this moment delay cut-off device (6) continues to give electromagnetic inductor (2) power supply, behind the certain hour, delay cut-off device (6) outage, electrical equipment or circuit quit work.When electrical equipment or circuit bump fire, fall phase time; the current ratio starting current that it produced is a lot of greatly; mobile armature (3) is attracted by the powerful magnetic force of electromagnetic inductor (2); mobile armature (3) directly contacts with electromagnetic inductor (2); master control shell fragment contact (8) disconnects at once; electrical equipment or circuit quit work, and reach the purpose of protection electrical equipment or circuit.
