Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, this high-voltage board comprises the lever lock 4 be arranged on the cabinet door 6 of high-voltage switch cabinet body 1;
Described lever lock 4 is made up of electromagnetism rotating shaft 5, lower locking bolt 2, upper locking bolt 7 and lever lock cross bar 11;
Described electromagnetism rotating shaft 5 and the circuit breaker in high-voltage switch cabinet body 1 connect and compose the lock core of lever lock 4;
Described lower locking bolt 2 connects by lever lock cross bar 11 the lever lock body structure that upper locking bolt 7 forms lever lock 4;
Described electromagnetism rotating shaft 5 is made up of the electromagnet of switch-on coil 10;
Be provided with below described lever lock cross bar 11 and be mated travel switch 3.
Unlatching and the locking principle of this high-voltage board are as follows:
As shown in Figure 3, now high-voltage switch cabinet body 1 is not charged, and maintenance personal can open the door and enter;
When needs locking cabinet door 6, namely when high-voltage switch cabinet body 1 is energized and runs, as depicted in figs. 1 and 2, electromagnetism rotating shaft 5 obtains electric by the circuit breaker in high-voltage switch cabinet body 1, and under magnetic fields, electromagnetism rotating shaft 5 is rotated, and drive lower locking bolt 2 and upper locking bolt 7 relative motion by lever lock cross bar 11 and insert in the keeper channel 8 on high-voltage switch cabinet body 1, lower locking bolt 2 and upper locking bolt 7 are by keeper channel 8 impede motion, and now electromagnetism rotating shaft 5 stops operating, and complete the locking action of cabinet door 6;
When cabinet door 6 opened by needs, need to ensure the circuit breaker power-off in high-voltage switch cabinet body 1, namely electromagnetism rotating shaft 5 dead electricity, can open cabinet door 6;
When high-voltage switch cabinet body 1 is charged, cabinet door 6 is opened, lower locking bolt 2 and upper locking bolt 7 can not by keeper channel 8 impede motions, when lower locking bolt 2 and upper locking bolt 7 are by continuation campaign, the lever lock cross bar 11 of electromagnetism rotating shaft 5 is rotated further, now by travel switch 3, the lever lock cross bar 11 be rotated further is hindered, when lever lock cross bar 11 touches travel switch 3, electromagnetism rotating shaft 5 will stop operating, electric shock is compressed by travel switch 3 simultaneously, and send alarm signal by the alarm device in high-voltage switch cabinet body 1, send warning to maintenance personal.
Further, as shown in Figure 4, in described electromagnetism rotating shaft 5, the coil 10 of access is connected with heat sink resistance 9.Electric current in the electromagnetism rotating shaft 5 stopped operating when cabinet door 6 locking, can be shunted by heat sink resistance 9, is that heat energy dissipates by heat sink resistance 9 by this part electric energy conversion, thus realizes the effect of protection coil 10.
In sum, this high-voltage board adopts the mode of electromagnetism rotating shaft lock, and structure is simple, safe and reliable, effectively reduces the possibility of the misoperation of attendant.Improve the coefficient of safety of high-voltage board and attendant.
