Description
Technical field
The utility model relates to a kind of earth leakage circuit breaker, makes it possible to whether external circuit opens circuit when abnormal current occurring, so that inform line broken circuit clearly.
Background technology
Usually, the earth leakage circuit breaker is a kind of equipment that is used for protecting by open circuit when abnormal current or overcurrent such as leakage current, when causing the generations such as earth fault current of electric shock electric appliance load device and personal safety.
Most of industrial earth leakage circuit breakers have the disconnection of disconnection electric leakage and detection of excessive current or short circuit to prevent the function of accident.The parts that the realization electric leakage shows separate with the parts that produce overcurrent/short circuit current, and therefore industrial earth leakage circuit breaker needs display unit.
For this reason, the earth leakage circuit breaker is provided with the electric leakage display unit of informing whether the user has abnormal current to produce.
Fig. 1 is the viewgraph of cross-section of a kind of earth leakage circuit breaker of prior art, Fig. 2 is the perspective view of indicating mechanism of a kind of earth leakage circuit breaker of prior art, Fig. 3 is the plan view of indicating mechanism of a kind of earth leakage circuit breaker of prior art, Fig. 4 is according to the indicating mechanism of the prior art viewgraph of cross-section along the intercepting of the line A-A among Fig. 3, clearly show that the major part of indicating mechanism like this.
Referring to attached Fig. 1 and 2, comprise according to a kind of earth leakage circuit breaker of prior art: be used for the excessive current detection unit 102 of detection of excessive current, wherein the grade of this overcurrent has surpassed the current class of power terminal 100 inputs of predetermined permission; Abnormal current detecting unit 104 is used to detect the abnormal current (leakage current, earth fault current or the like) of the electric current of power terminal 100 inputs; Switching mechanism 108, this switching mechanism 108 can be switched to and conducts on the position, so that electric connection of power supply terminal and load terminal or open position, so that when overcurrent or abnormal current are detected by excessive current detection unit 102 or abnormal current detecting unit 104, to avoid being sent to load terminal from the electric current of power terminal 100; Indicating mechanism 110, when when abnormal current detecting unit 104 transmits the signal of telecommunication, indicating mechanism's 110 start switching mechanisms 108 and externally the display abnormality electric current whether occur; And handle 112, this handle returns to normal condition to the earth leakage circuit breaker from off-state after the reason that produces abnormal current is eliminated.
Shown in Fig. 2 to 4, indicating mechanism comprises: bar 120, its both sides are opening and inner space that have predetermined volume; Be arranged on the driver element 121 in the bar 120, this driver element 121 is sent to signal of telecommunication start on it by abnormal current detecting unit 104; Action bars 122, it is arranged on the middle part of bar 120, but straight line move, it is according to the operation of driver element 121 and moving linearly; Be arranged on the trip rod 126 of action bars 122 1 ends, it rotates according to moving of action bars 122, thereby the cross bar 124 of impact switch mechanism 108 disconnects switching mechanism 108; With the electric leakage indicating device 131 that is arranged on action bars 122 other ends, it externally shows the electric leakage state according to moving of action bars 122.
Returning spring 138 is arranged on the end of action bars 122, so that after operating operation bar 122 action bars 22 is returned to initial position.
One end of trip rod 126 connects with jointed shaft 141, and trip rod keeps contacting with an end of action bars 122.Arm spring 140 is arranged on the jointed shaft 141, is used in one direction rotatory force being applied to trip rod 126.
Electric leakage indicating device 131 comprises: rotate to discharge the lock pin 142 of locking by moving of action bars 122; The electric leakage instruction button of when the rotation by lock pin 142 discharges locking, outwards protruding 144; Indicating arm 146, it is connected into one so that move with the lower end of electric leakage instruction button 144, and has hooked projection 151 in the one side, and this hooked projection 151 is by stretching out on the bottom that is hooked in lock pin 142; With spring 148, this spring is assemblied in a side of electric leakage instruction button 144 and provides elastic force to make that electric leakage instruction button 144 rises when locking is released.
When the indicating mechanism of above-mentioned structure during by normal start, removable core 134 is defined by the magnetized fixedly core 132 of magnetic force by permanent magnet 130.When the generation owing to abnormal current makes the signal of telecommunication with supply voltage be applied on the trip coil 128, the suffered qualification of removable core 134 by trip coil 128 and fixedly the magnetization between the core 132 offset and be released.Therefore, trip rod 126 rotates so that realize opening operation.
In other words, when leakage current produced, as shown in Figure 5, abnormal current detecting unit 104 detected the generation of leakage current, so that the signal of telecommunication is sent in the indicating mechanism 110.The signal of telecommunication with supply voltage imposes on trip coil 116 subsequently, so that the magnetization of trip coil 116 is offset by the magnetization by permanent magnet 130 magnetized fixedly cores 132.Therefore, removable core 134 suffered qualifications are released.
When removable core 134 suffered qualifications were released, trip rod 126 rotated by the elastic force of arm spring 140, so that promoted the cross bar 124 of action bars 122 and impact switch mechanism 108.In this case, the opening operation of switching mechanism 108 is realized by the rotation of cross bar 124, is cut off by the electric current of power supply to load.
In addition, action bars 122 moving linearlies make electric leakage instruction button 144 rise, and inform that thus the user has electric leakage to produce.
In other words, action bars 122 moves on the left direction of figure, lock pin 142 is rotated consequently discharge from hook-shaped projection 151.Like this, locking is released.Housing from the earth leakage circuit breaker stretches out electric leakage instruction button 144 by the elastic force of spring 148 subsequently, informs that thus the user has electric leakage, earth fault current, or human body electric shock phenomenon takes place.
After abnormal current reason in the load was got rid of, handle 112 was pushed closing direction to so that when reusing the earth leakage circuit breaker, and trip rod 126 overcomes the elastic force of spring 140 and rotates, and the electric power of supplying with trip coil 128 is cut off.Fixedly core 132 is magnetized again, so that movable core 134 closely is attached to fixedly core 132.
In addition, indicating arm 146 is pulled to the bottom direction by driving handle 112, so that make electric leakage instruction button 144 turn back to initial condition.And lock pin 142 is rotated by the elastic force of lock pin spring 160, so that hook by hooked projection 151.
Yet, in said structure and aforesaid operations according to the earth leakage circuit breaker of prior art, the electric leakage indicating mechanism that is used to indicate electric leakage to produce comprises many parts, lock pin for example, lock pin spring, electric leakage instruction button, spring, indicating arm or the like has increased manufacturing cost and has reduced efficiency of assembling owing to labyrinth thus.
In addition, electric leakage indicating mechanism according to prior art comprises a plurality of parts, these parts are mutually related and operate the generation of indicating electric leakage, its mode of operation is: lock pin rotates, so that discharge from hook-shaped lock pin, and the electric leakage instruction button is outwards outstanding by the elastic force of spring, has increased the possibility that operating trouble or operating mistake occur thus.
In addition, beyond the outwards outstanding earth leakage Shell of circuit breaker of electric leakage instruction button, occur with the expression leaky, so the user can not discern the appearance of leaky at an easy rate.
