For this reason, as shown in Figure 4, the withstand voltage test of above-mentioned manual operation formula is located at the side of operating handle 4 side by side with switch 21, is installed on the top position of the cross bar 20 that opens circuit of switching mechanism.In addition, on the case lid 11b of the top of main body case shell, be provided with the tegillum 11b-1 of slidingtype, so as can be from the outside to this withstand voltage test with switch 21 connect, opening operation.
Fig. 5 (a) and (b) are represented the concrete assembly structure of this withstand voltage test with switch 21.That is, this withstand voltage test forms with the assembly of switch 21 by following assembly parts, and these assembly parts comprise several slide switches 24, and the quantity of this slide switch 24 is corresponding with number of contacts; The switch-box shell 25 of vessel shape, this switch-box shell about 25 holds this slide switch 24 abreast; The switch cover 26 of slidingtype, this switch cover 26 is covered on the switch-box shell 25, engage with the operating knob 24a of slide switch 24, with each slide switch 24 connect, opening operation, and on switch cover 26, the actuator 26a of the integrally formed leg shape that extends downwards.In addition, in illustrated example, be provided with 2 slide switches 24 that the residual current circuit breaker of 3 phases is used, still,, adopt 1 slide switch 24 for single-phase residual current circuit breaker.
In addition, if this withstand voltage test is assemblied in position shown in Figure 4 with switch 21, then in this position, the front end of above-mentioned actuator 26a is in the state relative with the cross bar that opens circuit of switching mechanism, as shown in Fig. 6 (a) and (b), make actuator 26a and open circuit interlocking between the cross bar 20.
The normal main circuit "on" position that Fig. 6 (a) is expressed as follows: at withstand voltage test shown in Figure 5 switch 21, carry out operation that this switch cover 26 is slided to the right, slide switch 24 is remained on on-position, and make operating handle 4 be set in connection (ON) position, movable contact 15 is connected, it is corresponding with following state, at this state, the withstand voltage test of Fig. 1 by power line 9, is powered to electric-leakage detection circuit 7 from main circuit 1 with the closing of contact of switch 21.In addition, at this state, as Fig. 6 (a), the cross bar 20 that opens circuit is not retrained by actuator 26a, keeps the latch 18 of switching mechanism 3 in the engaging mode.
From this state,, withstand voltage test is slided into disconnection (OFF) position with the switch cover 26 of switch 21, so that carry out withstand voltage test by operation from the outside.Thus, the contact of slide switch 24 disconnects, the power circuit of electric-leakage detection circuit shown in Figure 17 is disconnected, itself and main circuit 1 are disconnected, simultaneously as shown in Fig. 6 (b), be arranged on the switch cover 26 actuator 26a from behind, push the cross bar 20 that opens circuit, make this cross bar 20 that opens circuit around bolster 20a, in the counterclockwise direction rotation.Thus, the latch 18 that remains on this cross bar 20 that opens circuit in the engaging mode is up till now discharged, open-close mechanism section 3 action of tripping, movable contact 15 is realized opening circuit, main contacts 2 disconnections.Then,, carry out withstand voltage test, then electric-leakage detection circuit 7 and main circuit 1 are disconnected, can make this electric-leakage detection circuit not be subjected to putting on the influence of the alternate higher test voltage of main circuit 1 safely if at this state.
In addition, withstand voltage test is being slided into the state of Fig. 6 (b) of the operation of open position with switch 21, remaining on the off-position of latch 18 being pressed against the cross bar 20 that opens circuit on the actuator 26a of this switch.So, after withstand voltage test finishes, short of withstand voltage test is turned back to original on-position with switch 21, even then operating handle 4 is being moved under the situation of (RESET) position that resets from trip position, still bolt lock mechanism portion is not resetted, thus, can't connect main contacts 1 once more.Thus, can prevent following situation from now on, that is, owing to forget connection withstand voltage test switch 21, Earth Fault Detection, the creepage protection function of residual current circuit breaker do not work.
In addition, open-close mechanism section 3 open circuit cross bar 20 under the elastic force effect of more weak back-moving spring (not shown), towards afterburning along clockwise direction with the clamped position (reset position) of latch 18.So, if set the connection of slide switch shown in Figure 4 24, the mechanical retention of open position bigger than the reseting elasticity of this cross bar 20 that opens circuit, then at the state that carries out withstand voltage test is slided into switch 21 operation that resembles the open position Fig. 6 (b), these cross bar 20 opposing back-moving springs that open circuit remain on the latch off-position.So, after withstand voltage test finishes, only otherwise withstand voltage test is turned back to on-position with switch 21 from disconnection, the cross bar 20 that then opens circuit does not reset, thus, even operating handle 4 is being carried out still latch 18 not being resetted under the situation of reset operation from tripping operation (TRIP) position, thus, can not connect the main circuit contact.Like this, after withstand voltage test finishes, when residual current circuit breaker is turned back to "on" position, can prevent to forget the mistake that withstand voltage test is resetted with switch 21.
Also have,,, also can implement by following such interlocking device except setting than the big mode of the reseting elasticity of the cross bar 20 that opens circuit with connection, the disconnection confining force of switch 21 withstand voltage test as the foregoing description.Promptly, if carry out withstand voltage test is moved to switch 21 operation of open position, then this switch constraint is remained on open position, after withstand voltage test finishes, carry out operating handle 4 is moved to from tripping operation (TRIP) position the operation of (RESET) position that resets, at this moment, follow this action, the cross bar 20 that will open circuit returns to reset position, simultaneously, the reseting elasticity by the cross bar 20 that opens circuit returns to on-position with withstand voltage test with switch 21, realize interlocking, in this occasion, same as the previously described embodiments, after withstand voltage test finishes, when residual current circuit breaker is returned to "on" position, can prevent to forget the mistake of connection withstand voltage test with switch 21.
Have again, in illustrated embodiment, with adopting slide switch 24 in the switch 21, still, be not limited to this in withstand voltage test, such as, also can implement according to the mode that adopts toggle switch.
