Abstract
The utility model provides a lighting device mounted in a switch cabinet instrument chamber, which comprises lighting fixture, a control switch, connecting wires, a power supply and a fuse protector, wherein the lighting fixture is mounted at the upper part on one side of a hinge of the instrument chamber, and is provided with a translucent protecting hood, an electric light source is mounted in the lighting fixture, and the live wire of the power supply is connected to the lighting fixture after passing through the fuse protector and the control switch in sequence, and is returned to the neutral wire of the power supply through the other end of the lighting fixture. The device solves the inconvenience due to lack of illumination in the switch cabinet instrument chamber, thereby being favorable for the safety during overhaul, and the visual fatigue of operating and maintenance staff is alleviated.
Description
Technical field
The utility model relates to a kind of power supply or panel switches cabinet, is specifically related to the lighting device in a kind of high-tension switch cabinet.
Background technology
Existing high-tension switch cabinet only is equipped with lighting apparatus in the cable vault, any lighting apparatus is not then installed by the control room, and this makes troubles for inspection and the indoor equipment of maintenance instrument, and is particularly under the situation of switch cubicle extraneous light deficiency, all the more so.
Summary of the invention
The purpose of this utility model is to provide a kind of lighting device that is installed in the switch cabinet instrument room, solves in inspection, the inconvenience of checking meter and bringing because of insufficient light when overhauling the indoor equipment of instrument.
The technical solution of the utility model is: the lighting device in a kind of switch cabinet instrument room, comprise light fixture, gauge tap, connection lead, power supply and fuse, described lamp installation is at hinge one upper lateral part of control room, light fixture has the printing opacity guard shield, in establish electric light source, the live wire of power supply through fuse and gauge tap, is connected to light fixture successively, gets back to the zero line of power supply again through the other end of light fixture.
Described gauge tap can be rotary switch or limit switch.When being used for metering cabinet, because on the instrument door glass window is arranged, do not need to open the instrument door, gauge tap should be the rotary switch that is contained on the instrument door, connects switch when needing illumination, and the time spent does not close; Other cupboard gauge taps should be selected limit switch for use, are installed on the instrument doorframe, and lamp is just bright when turning on the instrument door.
Described electric light source can be incandescent lamp or miniature energy-saving fluorescent lamp.The power supply of illumination can be to exchange, and also can be direct current, and when mains lighting supply was direct current, electric light source should adopt incandescent lamp.
The beneficial effects of the utility model are: the utility model has solved the inconvenience that does not have illumination to bring in the switch cabinet instrument room, and the safety when helping overhauling has alleviated operation and maintainer's visual fatigue.
Description of drawings
Fig. 1 is for adopting switch cubicle schematic side view of the present utility model;
Fig. 2 is the front schematic view of Fig. 1;
Fig. 3 is an illuminated circuit diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in Fig. 1,2 and 3, lighting device in a kind of switch cabinet instrument room, comprise light fixture 4, gauge tap, connection lead, power supply 8 and fuse 7, described lamp installation is 3 hinge one upper lateral part in the control room, light fixture has the printing opacity guard shield, in establish electric light source, the live wire of power supply 8 is successively through fuse 7 and gauge tap, be connected to electric light source 4, get back to the zero line of power supply 8 again through the other end of electric light source 4.
Described gauge tap can be rotary switch 6 or limit switch 1.When being used for metering cabinet, because on the instrument door glass window is arranged, do not need not allow to open the instrument door yet, gauge tap should be the rotary switch 6 that is contained on the instrument door 2, connects switch when needing illumination, and the time spent does not close; Other cupboard gauge taps should be selected limit switch 1 for use, are installed on instrument door 2 frames, and lamp is just bright when turning on instrument door 2.
Described electric light source can be incandescent lamp or miniature energy-saving fluorescent lamp.The power supply 8 of illumination can be to exchange, and also can be direct current, and when mains lighting supply was direct current, electric light source should adopt incandescent lamp.
Switch cabinet instrument room 3 is located in the cabinet 5, and light fixture 4 is installed in the top of control room's 3 left plates, can not cover light when operating with the right hand.
