Description

Drawer type switch cabinet capable of realizing automatic switching on and off

Technical Field

The utility model relates to an electrical control field especially relates to a drawer type switch cabinet that can realize automatic divide-shut brake.

Background

The drawer type switch cabinet is a closed shell made of steel plates, a switching-on and switching-off mechanism and a locking mechanism are arranged in the closed shell, and electrical components of a wire inlet and outlet loop are all installed in an extractable drawer to form a functional unit capable of completing a certain type of power supply task. The existing drawer type switch cabinet has the following problems: 1. the switching-on and switching-off mechanism is easy to age and wear because the transmission mechanism is made of plastic, casting parts and springs in multiple choices. Operator information cannot be recorded. 2. The locking device adopts a mechanical lock, the locking plate is in a sheet shape, the drawer is easily pulled out by an operator by mistake, and the safety accident of the electrical safety accident is easily caused by violating the principle that the isolating switch is closed first and then separated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the above-mentioned problem that prior art exists, provide a drawer type switch cabinet that can realize automatic divide-shut brake.

The utility model discloses a technical solution is that a drawer type switch cabinet capable of realizing automatic opening and closing comprises an AC220V power input end, a DC12V power supply, and is characterized by further comprising a relay KA1, a relay KA2 and a relay KA3, a first control circuit and a second control circuit are respectively connected between the DC12V power supply and the system ground through a fingerprint switch and/or a code switch with a recording function, a third control circuit, an electronic lock control circuit and an illumination indicating circuit are respectively connected between the DC12V power supply and the system ground, the first control circuit comprises a normally closed contact KA3-1 of the relay KA3, a normally closed contact KA2 and 2-1 of the relay KA 3653 in series connection, and a normally open contact 1-2 of the relay KA1 and a normally open contact 1-1 in parallel connection with the normally closed contact KA 72-1 of the relay KA1, the normally open contact and the normally open contact 1-1 of the relay KA1 and a normally open contact 1-1 and a normally open contact of the relay KA1-1 and a normally open circuit of the switch 72-1 and a normally open circuit of the switch system, the normally open circuit and a normally open switch and a normally open circuit of the switch 72-1 and a normally open circuit of the normally open switch system, wherein the normally open circuit and the normally open switch and the normally open relay are connected in series connection of the normally open relay KA-1, the normally open circuit and the normally open relay.

The utility model has the advantages that: the control mode of the opening and closing transmission mechanism is changed into fingerprint or password, and the information of the operator can be accurately recorded and stored. The electromagnetic automatic opening and closing switch is adopted, so that the problem that the normal power supply of the switch is influenced due to the aging and damage of an original mechanical opening and closing mechanism is solved. The locking device is changed into an electronic lock, when the switch is in a switch-on position, the electronic lock automatically locks the drawer cabinet, and the switch cannot be pulled out when in a power-on state; when the switch is in the opening position, the electronic lock is automatically opened, so that the safety of operators and equipment is ensured.

Detailed Description

As shown in figure 1, the drawer type switch cabinet capable of realizing automatic opening and closing comprises an AC220 power input end, a DC12 power supply, a relay KA and a relay KA which are led in through a power line, N and a power switch, a first control circuit and a second control circuit are respectively connected between the DC12 power supply and a system ground through a fingerprint switch K and a password switch (the password switch adopts a matrix key or can be a fingerprint switch or a password switch singly), the fingerprint switch K and the password switch with recording functions comprise a fingerprint switch module (model TFS-T), a single chip microcomputer, a memory, a clock chip, a display panel, a memory and a buzzer, the models of all units are shown in figure 2, the first control circuit comprises a normally closed contact KA-1 of the relay KA connected in series, the normally closed contact KA-1 of the relay KA and a normally open contact-2 of the relay KA-and a normally open contact KA-normally open relay KA-contact connected in parallel with the normally closed relay KA-1, the normally open contact KA-1 and the normally open contact KA-2 of the relay KA-5, the normally open contact KA-2-normally open contact and the normally open contact of the relay KA-relay are connected in series between the normally closed relay KA-contact KA-1 and the normally open contact KA-normally open contact of the relay KA-contact KA-5-relay, the normally open relay and the normally open relay system, the normally open contact of the normally open relay is connected in series, the normally open contact.

The working principle of the utility model is as follows:

1. and (5) power supply, namely, pushing the switch cabinet into the running position, lighting a power indicator L2 (red light), and outputting 12V voltage as a control loop power supply by a DC12V power supply.

When a fingerprint switch K1 is pressed or a password is input (if the password is input and identity information is input at the same time), a coil of a relay KA1 is electrified, attracted and self-protected, a coil of a relay KA3 is electrified, attracted and self-protected, a closing coil YC is electrified and automatically closed, a coil S of an electronic lock is electrified and locks the switch to be locked and cannot be pulled out, an operation indicator light L1 (green light) is turned on to start operation, a power indicator light L2 is turned off, and the opening time and the information of an operator are recorded at the same time.

2. Power failure: when the fingerprint switch K1 is pressed again or a password is input, the coil of the electrical appliance KA1 loses power, the coil of the relay KA2 is electrified and attracted, the normally closed contacts KA2-1 and KA 2-3 of the relay KA2 are disconnected, and the coil of the relay KA3, the closing coil YC and the electronic lock S are simultaneously powered off. The opening coil YT is electrified and automatically switched off, the green light is turned off, the running is withdrawn, the red light is turned on, and meanwhile, the stop time and the operator are recorded.
