Abstract
A kind of output-controlling device of electron type motor protector; it comprises stop button SB1; one end and phase line L; collection draws equipment a end to be connected with fault detector H one end; the other end is connected with the contact of start button SB2 one end and contactor KM; another contact of the start button SB2 other end and contactor KM is connected with an end of relay J 1; the other end of relay J 1 is connected with an end of contactor KM coil; the other end of contactor KM coil is connected with collection control equipment b end with zero line N; the fault detector H other end is connected with an end of relay J 2, and the other end of relay J 2 is connected with collection control equipment b end with zero line N.The utility model is owing to adopt double relay independently to control motor action and the output of reporting to the police; solved the failure problems that occurs false alarm in the motor centralized control; guaranteed that the safety of motor protector normally uses, made motor protector safer, reliable the protection of motor.
Description
Technical field
The utility model relates to a kind of output-controlling device of motor protector, particularly a kind of output-controlling device of electron type motor protector.
Background technology
Motor protector mainly replaces thermal overload relay, provides protection to alternating current motor safe in utilization.In the existing electron type motor protector, the output-controlling device of protector generally only is provided with an actuating relay, is used for controlling the controller and the warning device of output signal, thereby realizes the purpose of control motor and external output alarm.But in actual use; motor protector generally all is contained in the power distribution cabinet; the Motor Control great majority are centralized control; the control power supply is independently-powered, in this case, and a, b termination collection control equipment; when central controlled arbitrary motor normally stopped using; protector is cut off the electricity supply, and contact 07,08 closure will be reported failure alarm signal by mistake.
Summary of the invention
It is central controlled that the purpose of this utility model provides a kind of motor that is applicable to, the output-controlling device of electron type motor protector that can false alarm.
The purpose of this utility model reaches like this; a kind of output-controlling device of electron type motor protector; it comprises stop button SB1; one end and phase line L; collection control equipment a end is connected with fault detector H one end; the other end is connected with the contact of start button SB2 one end and contactor KM; another contact of the start button SB2 other end and contactor KM is connected with an end of relay J 1; the other end of relay J 1 is connected with an end of contactor KM coil; the other end of contactor KM coil is connected with collection control equipment b end with zero line N; the fault detector H other end is connected with an end of relay J 2, and the other end of relay J 2 is connected with collection control equipment b end with zero line N.
The utility model is owing to adopt double relay independently to control motor action and the output of reporting to the police; the failure problems that occurs false alarm in having separated the motor centralized control inferior; guaranteed that the safety of motor protector normally uses, made motor protector safer, reliable the protection of motor.
Accompanying drawing and drawing explanation
Fig. 1 is the electrical schematic diagram of the output-controlling device of single relay.
Fig. 2 is an electrical schematic diagram of the present utility model.
Embodiment
SB1 is a stop button, presses SB1, cuts off the electricity supply, and this device quits work.SB2 is a start button, presses SB2, and contactor KM coil gets electric, contactor KM contacting, this device work.J1 is control motor action relay, and J2 is control motor output relay.The normal condition of regulation protector energising now is a reset condition; this moment, the contact 05,06 of relay J 1 was normally closed; all the other situations are off-state; the contact 05,06 of relay J 1 is serially connected in the major loop contactor KM coil; realize only ability actuating motor after the protector operate as normal like this, the loss of having avoided some improper factors to cause.The contact 07,08 of relay J 2 is the warning output contact, and contact 07,08 disconnects closure during motor fault when reset condition and protector outage.Therefore, when protector detects motor fault, two control relay J1, J2 move simultaneously, and open contact 05,06, cut off motor power, contact 07,08 closure, and output alarm signal is accomplished error protection and the output of reporting to the police.
