The working principle and the beneficial effects of the technical scheme are as follows: the locking plate 10 and the protection lock 9 are respectively located on two doors of the shielding door 7, taking fig. 6 as an example, the locking plate 10 is installed on the left door of the shielding door 7, the protection lock 9 is installed on the right door, when the distribution box leaks electricity, if the voltage is too large, the shielding door 7 is electrified, at this time, after the current passes through the trigger 91, the trigger 91 is started to drive the trigger rod 92 to move rightwards, the linkage member 96 at the left end of the trigger rod 92 drives the right end of the lock head 97 to move relatively, so that the left end of the lock head 97 located in the locking plate 10 moves relatively, so that the lock head 97 and the locking plate 10 are clamped, locking of the shielding door 7 is realized, at this time, the second elastic member 98 is in a stretching stress state, the ejector rod 93 located at the right end of the trigger rod 92 moves rightwards under the driving of the trigger rod 92, under the pulling force of the third elastic member 942, the rotating block 941 rotates, and keeps the right end abutting against the ejector rod 93, the left end of the rotating block 941 is separated from the chuck 954, then the display bar 952 moves leftwards along the sliding groove 951 and is inserted into the left door of the shield door 7 under the action of the elastic force of the fourth elastic member 953, the end of the display bar 952 is coated with corrosion-resistant pigment, because the shield door 7 is of a fine mesh structure, after the end of the display bar 952 is inserted into the left door, the color of the end of the display bar 952 can be seen from the mesh of the shield door 7, so as to remind an operator that the shield door 7 is in a locked state at present, and the distribution box leaks electricity, the operator can select to power off the distribution box or forcibly open the shield door 7 according to actual needs, if the operator needs to forcibly open the shield door 7, the lock head 97 can be pinched by a tool to unlock the lock head 97 from the lock plate 10, if the operator adopts a power-off mode, the trigger lever 92 resets, thereby make linkage 96 reset, and the tip of tapered end 97 separates with the locking plate 10 under the effect of second elastic component 98, in order to relieve the locking of shield door 7, ejector pin 93 resets and extrudes turning block 941 and makes it rotate, the left end of turning block 941 then can block into in dop 954, and take dop 954 translation, and then make the translation of display strip 952 withdraw along spout 951, display strip 952 takes in back shield door 7's right side door in with colored tip this moment, through the design of above-mentioned structure, when the block terminal leaks electricity, protection lock 9 can be automatic to lock with locking plate 10 in order to avoid operating personnel to open shield door 7 and destroy the inside electric potential balance and cause the electric shock, still can carry out the suggestion of leaking electricity to operating personnel through display strip 952 simultaneously, so that operating personnel knows the reason of shield door 7 locking.
In one embodiment, since the distribution box may generate voltage and current due to mutual inductance between the distribution box and the anti-electric shock component after being powered on, and thus may cause the trigger 91 to trigger erroneously, the mutual inductance voltage M should be calculated according to the following formula when the trigger 91 detects the voltage
M is mutual induction voltage between the distribution box and the electric shock prevention assembly after being electrified; i.e. i 1 Self-induced current of the anti-electric shock component; r s The internal resistance of the electric shock prevention component; l is s The self-inductance of the electric shock prevention assembly is achieved; u. of 0 The inductance voltage of the anti-electric shock component; i.e. i 2 Is a mutual inductance current; t is a unit time;
wherein,
wherein, C s Is a stray capacitance; r L Is the resistance of the distribution box; the above formula can be integrated into
Can calculate through above-mentioned formula under the circumstances of block terminal normal circular telegram, the mutual inductance voltage value that protection against electric shock subassembly can produce, trigger 91 can compare the mutual inductance voltage who calculates gained and the safe voltage (generally not higher than 36V) that trigger 91 set for, if mutual inductance voltage is higher than safe voltage, then trigger 91 starts in order to lock shield door 7, when mutual inductance voltage is less than safe voltage, trigger 91 does not start, through above-mentioned formula, can adjust the sensitivity of trigger 91, thereby avoid trigger 91 false triggering, lead to shield door 7 to lock often, and then make this protection canopy more intelligent, can be suitable for more occasions, and avoid trigger 91 false triggering to lead to electrician's ineffective maintenance often, detect, thereby reduce the artifical maintenance cost of protection canopy.
