Detailed Description
The following detailed description is provided with the accompanying drawings, as shown in the figure, the box comprises a box body 8 and a box door 1, an electromagnetic lock 5 and a charged display 6 are installed on the box door 1, and an air switch 7 is installed on an installation beam in the box 8. The wiring terminals 1 and 3 of the air switch 7 are respectively connected with an indoor alternating current live wire and a zero line or a direct current positive control bus (+ KM) and a negative control bus (-KM), the outgoing wiring terminal 2 of the air switch 7 is connected with an auxiliary point K1 of the electric display 6, the auxiliary point K2 of the electric display 6 is connected with the wiring terminal 1 of a coil of the electromagnetic lock 5, the wiring terminal 2 of the coil of the electromagnetic lock 5 is connected with the outgoing line terminal 4 of the air switch 7, the three phases A, B and C of the electric display 6 are correspondingly connected with the three phases A, B and C of the bus 4, the bus 4 is connected with the sensor 2 and the high-voltage insulator 3, the sensor 2 and the high-voltage insulator 3 are fixed in the box body 8 through supports, the side part of the box body 8 is provided with heat dissipation holes 9, and the heat dissipation holes are used for protection, so that sundries such as small animals and leaves are prevented from entering the box.
The utility model discloses a support electrified female arranging through the sensor, whether electrified display monitoring return circuit is electrified, then control the electromagnetic lock coil through the auxiliary point of electrified display and realize that the chamber door can not open under the electrified circumstances, guarantee the safety problem that the indoor cable distribution box person electrocuted. The specific working principle is as follows: the electromagnetic lock adopts a DSN3-SMY indoor electromagnetic lock, the sensor adopts BST610-003, the electrified display adopts a forced electrified display, the DZ47-6/2P for air mining and an indoor alternating current screen or a direct current screen of a power supply. When female arranging 4 is electrified, electrified display 6 senses the return circuit through sensor 2 and is electrified, and the pilot lamp of electrified display 6 will light, and the auxiliary point K1 of electrified display 6, K2 just can break off simultaneously, and the coil of electromagnetic lock 5 loses the electricity, and the electromagnetic lock handle lock dies, and chamber door 1 can not be opened. When the main loop is not electrified, the auxiliary points K1 and K2 of the electrified display 6 are closed, the coil of the electromagnetic lock 5 is electrified, and the box door 1 can be opened at will.
