Abstract
The utility model is additionally provided with a circuit for displaying blown fuse on a porcelain plug under the condition of unchanging a primary circuit and a fuse holder, so that the function of displaying a blown fuse by light can be realized, and a primary fuse plug can be directly replaced. When the malfunction of power cut is caused by a blown fuse due to circuit overload, distant surveillance can be realized, so that the fuse can be replaced conveniently and accurately even by people who know nothing about the knowledge of electrical engineering, and the time for seeking the malfunction can be saved.
Description
The present invention is a kind of over current protection electrotechnical apparatus that is applied in the low voltage electric network, is mainly used in the low-voltage electrical apparatus field.
The present Safety box of electric power supply that uses because fuse is hidden in box, when circuit breaks down when pulling out its safety plug and checking whether fuse fuses, has following inconvenience:
(1) general power safety device is installed in higher position, checks inconvenience;
(2) under the situation of many group insurances, cause easily by mistake and pull out other safety plug, thereby influence the operate as normal of other circuit;
(3) be ignorant of the personnel of electrician's knowledge, even the situation of blown fuse is not known failure cause and incured loss through delay the repairing time.
For addressing the above problem, the objective of the invention is on the basis that keeps former safety box modular construction, only its plug to be carried out a bit little improvement, tangible fusing Presentation Function can be arranged.
The present invention mainly is made of the illuminating circuit that the porcelain after improving is inserted, former inserted sheet and neon bulb and resistance are formed, and the electrical equipment in family and public place of suiting very much insures in the facility and uses.
Below in conjunction with accompanying drawing the present invention is elaborated:
Accompanying drawing 1 is the Visual of bowing figure of the present invention.
Accompanying drawing 2 is that A-A of the present invention cuts open Visual figure.
(1) uses neon bulb for showing in the accompanying drawing; (2) be-1/8 watt 50～200 kilo-ohms dropping resistor; (3), (4) are the holding screw of inserted sheet and assembly; (5) be the display circuit cover glass; (6) insert for the porcelain after changing; (7), (8) are former inserted sheet.Its design principle is: when the insurance operate as normal, the fuse at cross-over connection insurance inserted sheet (7) (8) two ends is not worked the display circuit short circuit; When blown fuse, electrical appliance forms the loop in display circuit and the load circuit, and at this moment neon bulb (1) is luminous, the purpose that has light to show when promptly having reached blown fuse.
The present invention is not changing original power safety system line and is not changing former Insurance Block and keep under the situation of all performances of former safety plug the function that can show automatically when increasing by a blown fuse.Be applicable to the user of family and all trades and professions use civil power, can convenient, accurately, promptly supervise the operating state of showing fuse, the trouble-shooting time is saved in realization distant surveillance.
Cost of the present invention is low, makes simply, only needs that porcelain is inserted (6) and stay a cavity that can hold display element when making, and the display circuit two ends is anchored on the holding screw (3) (4) of former inserted sheet (7) (8), covers cover glass sheet (5) and gets final product.
Claims (1)
- A kind of have fusing show can merit safety plug it is characterized in that porcelain is plugged a neon bulb (1) and resistance (2) be housed.
