Description
Technical field
The present invention relates to power supply or the shell and field of components of distribution, more particularly to a kind of earth leakage protective distribution
Case.
Background technology
Electrical equipment has become essential part in the life of modern people, however when using electrical equipment it some times happens that
The phenomenon of electric leakage, the reason for producing this phenomenon for circuit board itself is problematic or circuit in element make moist, dust stratification causes
Leak electricity, electric current can be experienced in touch appliance shell after electrical leakage.Such as the antenna of old-fashioned colour TV connects with circuit board, makes
The sensation of hand fiber crops can be produced when touching antenna by obtaining people, but the resistance that this household electrical appliances need to only use resistance larger will can leak electricity
Current control in the range of human body can be born.
After the situation of this electric leakage occurs the (distribution in the present invention may be damaged to the personnel close to distribution box
Case refers in particular to low-voltage direct distribution box), for people when solving the problems, such as this electric leakage, the mode of generally use ground connection makes electric current at present
Flow to the lower the earth of impedance, so as to avoid injury to personnel, but the distribution box in living to be frequently present of ground connection nonstandard
Phenomenon, cause later stage electric leakage to cause fire, while the drain conditions of distribution box can not be clearly known after being grounded, to electric power resource
It also result in waste.
And produce pyrophoric distribution box after generation accident to be inherently fraught with risks, high-tension current will when people is close
Break up air to beat to close people, make one to be difficult to close cut off the electricity supply so that cause damage to personal property further expansion.
The content of the invention
The invention is intended to provide a kind of earth leakage protective distribution box, to solve distribution box of the prior art in electric leakage mistiming
The technical problem hurted sb.'s feelings.
Earth leakage protective distribution box in this programme, including electronic box shell, master on off, clamper and earth leakage protective device, its
Middle electronic box shell includes housing, cap, rotary shaft, and the rotary shaft is on housing, and the cap connects on the rotating shaft, cap energy
Cover on housing, master on off is in housing, and clamper is hinged on cap close to the side of master on off, and the clamper is standby
It is maintained at the same horizontal plane during state with master on off, earth leakage protective device is on the rotating shaft；
The earth leakage protective device includes：Motor, freewheel clutch and detection of electrical leakage module, motor connection is in overdrive clutch
On device, on the rotating shaft, detection of electrical leakage module is on cap, the electricity of the detection of electrical leakage module for the motor and freewheel clutch
Road is connected with diode, motor, clamper and switch.
When detection of electrical leakage module detects electric leakage, motor and clamper are powered and started, and motor driven freewheel clutch turns
Dynamic, freewheel clutch, which rotates, causes cap to be constantly turned out, and is gradually opened cap, and cap, which is opened, drives clamper movement,
The master on off that clamper is clasped when moving by clamper is closed, and reaches the purpose of power-off protection, while have already turned on cap side
Just staff overhauls, and electronic box shell is no longer powered after clamper leaves behind master on off, and motor is stopped, and clamper leaves total electricity
Lock.
Motor, which is set, can rotate on the rotating shaft motor rotational band turn moving axis, promote cap to open；By motor
It is connected with freewheel clutch and avoids cap from persistently being deformed by the power that motor provides；Clamper is hinged on one close to master on off
Side is left behind master on off when clamper is moved with the opening of cap.
After opening the switch on earth leakage protective device, when cap is powered, circuit communication, motor and controller start, control
Device processed sends closure signal to clamper, and clamper clamps master on off, while motor driven is arranged on the overdrive clutch on motor
Device rotates, the power being turned out to cap of freewheel clutch interruption, the electricity when cap opening drive clamper leaves behind master on off
Machine powers off so that freewheel clutch stops operating.
The cooperation of motor and the clamper that is arranged on cap on of this programme by setting on the rotating shaft, distribution box are leaking
When electric, housing is powered, the circuit communication of detection of electrical leakage module so that motor and clamper start, and clamper, which starts, clasps total electricity
Lock, electric motor starting drive freewheel clutch to rotate, and freewheel clutch interval applies the power being turned out to cap so that cap
To open, clamper moves out together with cap, so as to drive the master on off being fastened to close, distribution box power-off, wherein two
When what pole pipe make it that detection of electrical leakage module is connected to is alternating current electronic box shell will not be made powered, no longer powered on electronic box shell, motor
Powered off with clamper, motor stops that freewheel clutch is stopped operating, and clamper, which powers off, causes gripper return to unclamp total electricity
Lock, solves the technical problem that distribution box of the prior art is hurted sb.'s feelings in electric leakage mistiming.
Further, the clamper includes No.1 clamping pin, No. two clamping pin, No.1 torsion spring, actuating arm and No. two torsion springs,
No.1 torsion spring is provided between the No.1 clamping pin and No. two clamping pin, No.1 clamping pin and No. two clamping pin can make up one
The circle of closing, actuating arm connection No.1 clamping pin, No. two clamping pin and cap, the position that actuating arm connects with cap are provided with No. two
Torsion spring.When clamper is powered, actuating arm, which closes up, drives No.1 clamping pin and No. two clamping pin to close up the circle to form a closing,
So as to clamp master on off, when clamper no power, No.1 clamping pin and No. two clamping pin divide in the presence of No.1 torsion spring
Open so that clamper unclamps master on off, and when clamper is displaced outwardly with cap, clamper follows master on off to turn downwardly together
It is dynamic, lifted again in the presence of No. two torsion springs when clamper leaves master on off, sustained height when keeping opening with master on off.
Further, the material of the electronic box shell is energization material.It is electric compared to made of insulating materials when distribution box leaks electricity
The electronic box shell of case shell this programme, which is more prone to enough electric currents, makes motor and clamper powered.
Further, the detection of electrical leakage module is also in series with siren, and the siren is between diode and motor.If
Putting alarm can be such that people are ready before power-off afterwards, avoid electrical equipment from closing cause damage by force because of power-off.
Further, the detection of electrical leakage module is provided with time-delay mechanism between siren and motor.Compared to being not provided with prolonging
When the scheme alarmed again of device, this programme can give people more times.
Further, snap-in latch is provided between the housing and cap.Compared to hand knocker can more coordinate surmount from
Clutch opens cap.
