Abstract
The invention provides a lighting device mounted in a switch cabinet instrument room, which comprises a lamp, a control switch, a connecting conducting wire, a power supply and a fuse, wherein the lamp is mounted at the upper part on the side of a hinge of the instrument room, the lamp comprises a light transparent protective cover, an electric light source is arranged in the lamp, and a live wire of a power supply sequentially passes through the fuse and the control switch, is connected to the lamp and further returns to a neutral wire of the power supply via the other end of the lamp. The lighting device can solve the inconvenience caused by no lighting in the switch cabinet instrument room, be conductive to the safety during the overhaul and reducing the visual fatigue of operation and overhaul staff.
Description
Technical field
The present invention relates to a kind of power supply or panel switches cabinet, be 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 object of the present invention is to provide a kind of lighting device that is installed in the switch cabinet instrument room, solve in inspection, the inconvenience of checking meter and bringing because of insufficient light when overhauling the indoor equipment of instrument.
Technical scheme of the present invention 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 invention has the beneficial effects as follows: the invention solves the inconvenience that does not have illumination to bring in the switch cabinet instrument room, 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 invention;
Fig. 2 is the front schematic view of Fig. 1;
Fig. 3 is an illuminated circuit diagram of the present invention.
The specific embodiment
The invention will be further described 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.
