Abstract
The invention discloses an electrified display access control device applied to a 35KV electric switch cabinet, and relates to a high-voltage switch cabinet assisting device. The electrified display access control device comprises a signal collecting device (1), an electrified display control device (2), an access control device (3) and a power supply (4), wherein the signal collecting device (1) is connected with a bus, a guided-out signal line is connected with the electrified display control device (2), and the electrified display control device (2) is respectively connected with the access control device (3) and the power supply (4). According to the electrified display access control device applied to the 35KV electric switch cabinet, an access control system with the electrified display control device and an electromagnetic locking circuit are designed, the signal collecting device which is arranged in the electric switch cabinet is used for sensing an electrification signal of the bus to control the electrified display device to display that the switch cabinet is electrified and also control the power supply of the access control device to be switched off, so that a cabinet door is closed and cannot be opened till the bus is not electrified; therefore, the display is intuitive, and the personal safety accident caused by the fact that an operator carelessly enters the electric switch cabinet is prevented; the structure is simple, and the use is convenient.
Description
Technical field
The present invention relates to high-tension switch cabinet utility appliance, specifically a kind of charged demonstration entrance guard device for 35KV cabinet.
Background technology
For personal safety consider, relevant specification of country strict regulations in the charged situation of high-tension switch cabinet, forbid to open cabinet door.For this specification, power industry has been formulated strict operating duty.But the report that still has personal accident to occur, charged demonstration entrance guard device is exactly to take precautions against in charged situation people for opening by mistake cabinet door from technological means.Charged demonstration entrance guard device has two major functions, and the one, in the time of switch cabinet electrified, corresponding pilot lamp is lighted, and represents that this cabinet equipment is charged, reminds operator not open the door; Another function is automatic blocking cabinet door electromagnetic lock in the situation that of equipment live, even if occur that people operates by force, can not open cabinet door.Thereby increase again technically twice safety practice.
The bus of electrical equipment or wire, the equipment such as special high voltage, because of overtension, even still have within a certain period of time certain " residual voltage " after having a power failure, although this voltage does not have the voltage when charged so high, also there are hundreds of volts to the numerical value of several kilovolts, equally the person is had to serious danger, therefore, also have electric in the situation that on bus, charged demonstration entrance guard device can effectively avoid people to open at this moment cabinet door.
Summary of the invention
For solving the technical matters of above-mentioned existence, the invention provides a kind of charged demonstration entrance guard device for 35KV cabinet, can show that whether high-voltage board is in electriferous state, and judge that according to electriferous state whether cabinet door can be opened, and avoids causing security incident.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of charged demonstration entrance guard device for 35KV cabinet, comprise signal pickup assembly, charged display control unit, entrance guard device and power supply, the signal wire that described signal pickup assembly is connected, draws with bus is connected with charged display control unit, and described charged display control unit is connected with entrance guard device, power supply respectively.
Described signal pickup assembly is set to three groups of touch sensors, and the signal wire of described three groups of touch sensors is connected with the three-phase input contact of charged display control unit respectively.
Two output contacts of described charged display control unit are connected with the power supply of entrance guard device.
Described entrance guard device is by electric-magnetic lock the electric circuit constitute.
The present invention has designed the gate control system with charged display control unit and electric-magnetic lock circuit, by being positioned over the signal pickup assembly induction bus belt electric signal in cabinet, control charged display device display switch cabinet charged, and the disconnection of the power supply of access control device, cabinet door is closed and cannot be opened, until bus is not charged, cabinet door can be opened, and intuitive display is avoided operator to be strayed into cabinet and caused personal safety accident, simple in structure, easy to use.
Brief description of the drawings
Fig. 1 is electrical schematic diagram of the present invention;
Fig. 2 is entrance guard device of the present invention and signal pickup assembly circuit connection sketch.
Embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, this is used for the charged demonstration entrance guard device of 35KV cabinet, comprise signal pickup assembly 1, charged display control unit 2, entrance guard device 3 and power supply 4, the signal wire that described signal pickup assembly 1 is connected, draws with bus is connected with charged display control unit 2, and described charged display control unit 2 is connected with entrance guard device 3, power supply 4 respectively.
As shown in Figure 2, as preferred mode, described signal pickup assembly 1 is set to three groups of touch sensors 11, and the signal wire of described three groups of touch sensors 11 is connected with three-phase input contact A, B, the C of charged display control unit 2 respectively.Described entrance guard device 3 is made up of electric-magnetic lock circuit 31.Described electric-magnetic lock circuit 31 in the situation that of dead electricity, by electric cubicle switchboard cupboard door closure, electric in the situation that, the cabinet door electromagnetic lock of cabinet is opened, and can arbitrarily open cabinet door, enters the interval of cabinet.Two output contact K1, K2 of described charged display control unit 2 are connected with the power supply of the electric-magnetic lock circuit 31 of entrance guard device 3, control electric-magnetic lock circuit 31 power supply disconnection be connected, thereby the locking that realizes gauge tap cabinet door whether.
Three groups of touch sensor 11 one end connection line busbars, one end ground connection, draws signal wire and accesses the A of charged display control unit 2, B, tri-input contacts of C, the output contact K1 of charged display control unit 2, K2 is connected with electric-magnetic lock circuit 31.When in the charged situation of circuit busbar, three groups of touch sensors 11 can sense charged signal, and input charged display control unit 2, charged display control unit 2 carries out logic judgement according to signal, and pilot lamp lights, represent that cabinet is charged, charged display control unit 2 disconnects K1 simultaneously, K2 contact, and the power supply of entrance guard device 3 disconnects, electric-magnetic lock circuit 31 dead electricity, cabinet door cannot be opened; When after the power-off of circuit busbar, charged display control unit 2 judges according to input signal logic, closed K1, and K2 contact, the power connection of entrance guard device 3, electric-magnetic lock circuit 31 obtains electric, and cabinet door can be opened, and now can enter safely interval.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present invention, also should belong to protection scope of the present invention.
