Abstract
A ground wire cabinet comprises a cabinet body, a power source, an indicator lamp and a switch. The cabinet body is provided with a ground wire, the power source, the indicator lamp and the switch are arranged on the cabinet body, an anode or a cathode of the power source is sequentially connected with the indicator lamp, the switch and the cathode or the anode of the power source by conducting wires, and the switch is positioned below the ground wire. When the ground wire cabinet is not grounded, the ground wire is coiled in the cabinet body and presses the switch, so that the switch is in an open circuit state, and the indictor lamp is turned off; and when the ground wire cabinet is grounded, the ground wire is guided out of the cabinet body to be connected with the ground, the switch is in a closed circuit state under the action of a spring, and the indicator lamp is turned on to remind staff that the ground wire cabinet is grounded. The staff can clearly know whether the ground wire cabinet is grounded or not by observing whether the indicator lamp is turned on or not, and potential safety hazards are eliminated.
Description
Technical field
The utility model relates to a kind of operation power safety means, particularly a kind of earth connection cabinet.
Background technology
Existing earth connection cabinet is used for depositing the voltage levels earth connection, and high-voltage grounding wire is for circuit and Substation construction, guarantees the usefulness of safety when preventing that closing on electrified body produces electrostatic induction electric shock or false switching.Existing earth connection cabinet has the electric property of the effect protective earthing lines such as protection against the tide, sun-proof, constant temperature, but whether not prompting in cabinet of earth wire.When the earth connection of removing in using is forgotten in operating personnel error, do not have any obvious signal and remind rising, in case send the electricity may be to causing electric power accident to this circuit.
The utility model content
The purpose of this utility model just provides a kind of earth connection cabinet, and it can show whether ground connection of earth connection cabinet by indicator light, eliminates safe hidden trouble.
The purpose of this utility model is to realize by such technical scheme, it includes cabinet with earth connection, is arranged on power supply, indicator light and switch on the cabinet, the negative or positive electrode of power supply is connected with indicator light, switch and power supply negative pole or anodal the connection successively by wire, and switch is positioned at the below, position of earth connection.
Further, described switch is sensitive switch.
Further, described indicator light is installed on the side outer wall of cabinet.
Further, described switch is installed on the cabinet floor inwall.
Owing to having adopted technique scheme, having the utlity model has following advantage:
The earth connection cabinet is under earth-free state, and the ground connection drum is pressed on the switch in cabinet, makes switch be in off state, and indicator light is for extinguishing state; The earth connection cabinet is under the state of ground connection, and earth connection is drawn cabinet, is connected with ground, and switch is in channel status under the effect of spring, and indicator light lights, and reminds ground connection of staff's earth connection cabinet.Whether the staff lights by indicator light just can be known and know whether ground connection of earth connection cabinet, eliminates safe hidden trouble.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
Description of drawings
Description of drawings of the present utility model is as follows.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. cabinet; 2. earth connection; 3. power supply; 4. indicator light; 5. switch.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The earth connection cabinet, include the cabinet 1 with earth connection 2, also include the power supply 3, indicator light 4 and the switch 5 that are arranged on the cabinet 1, the negative or positive electrode of power supply 3 is connected with negative pole or the positive pole that indicator light 4, switch 5 are connected with power supply successively by wire, and switch 5 is positioned at the below, position of earth connection 2.
The earth connection cabinet is under earth-free state, and earth connection 2 dishes are pressed on the switch 5 in cabinet 1, make switch 5 be in off state, and indicator light 4 is for extinguishing state; The earth connection cabinet is under the state of ground connection, and earth connection 2 is drawn cabinet 1, is connected with ground, and switch 5 is in channel status under the effect of spring, and indicator light 4 lights, and reminds ground connection of staff's earth connection cabinet.Whether the staff lights by indicator light 4 just can be known and know whether ground connection of earth connection cabinet, eliminates safe hidden trouble.
Described switch 5 is sensitive switch.The contact spacing of sensitive switch is little, actuating length is short, press that power is little, break-make is rapid, can improve the reaction time of indicator light.
Described indicator light 4 is installed on the side outer wall of cabinet 1.
Described switch 5 is installed on the cabinet 1 bottom surface inwall.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (4)
1. earth connection cabinet, include the cabinet with earth connection, it is characterized in that: also include the power supply, indicator light and the switch that are arranged on the cabinet, the negative or positive electrode of power supply is connected with indicator light, switch and power supply negative pole or anodal the connection successively by wire, and switch is positioned at the below, position of earth connection.
