Definitions
- the present invention relates to a fire protection and protection system according to the misuse of the fuse, more specifically, when the user does not know the electric circuit and connects an excessive electric load and uses a high capacity fuse, the wiring exceeds the allowable capacity.
- a slow blow fuse (out of the normal fuse) is installed at the rear of the fuse. And fire protection and protection systems resulting from fuse misuse.
- the present invention was developed to solve the above problems, to protect the equipment from the risk of fire damage and wiring caused by electrical overload due to fuse misuse and incorrect circuit change, fire prevention and protection system according to fuse misuse
- the purpose is to provide.
- the load is any one of a lamp, a wiper motor, a fan motor, and an equipment controller installed in the boom or the cap.
- the slow blow fuse includes an element made of metal so that electricity can flow, a housing for fixing the element, a cover made of a transparent material to check the state of the fuse, and an inside of the housing in the element. Located and not in contact with the housing and the cover, it characterized in that it comprises a blown portion that is caused to rise and melt (or melt) when the overcurrent flows.
- the present invention protects the equipment from fire damage and wiring damage caused by electric overload due to fuse misuse and incorrect circuit change.
- FIG. 1 is a system diagram showing a fuse system of a typical vehicle
- Figure 2 is a system diagram showing a fire protection and protection system according to the fuse misuse according to the present invention
- FIG. 3 is a perspective view showing an example of a slow blow fuse usable in the present invention.
- the system exceeds the wiring allowance when the user does not know the electric circuit and connects an excessive electric load to use a high-capacity fuse.
- a slow blow fuse at the rear of the fuse is prevented.
- (Slow Blow fuse) (out of the normal fuse) 103 is provided to protect the equipment from fire damage and wiring damage caused by electric overload due to fuse misuse and incorrect circuit change.
- the slow blow fuse 103 is, for example, when using a high-capacity fuse having a rated capacity of 20A instead of a normal fuse having a rated capacity of 15A to a load, when the overcurrent flows to the load, The fuse exceeds the allowable range of wire thickness designed for the normal fuse 15A and the load, and the fuse burns without the fuse.
- the present invention provides a slow blow fuse 103 at a rear end of the fuse so that an overcurrent exceeding the maximum designed capacity flows through the slow blow fuse 103. It is a system to prevent dangers such as fire that can occur additionally by letting out.
- the concrete structure is installed between the high capacity fuse 101 and the load 102 having a rated capacity higher than that of the normal fuse installed according to the capacity of the load, and the temperature rises upon input of the overcurrent passing through the high capacity fuse 101.
- the melted portion is melted off (or melted) to block overcurrent flowing to the load.
- the slow blow fuse 103 is an element made of metal so that electricity can flow, a housing for fixing the element, a cover made of a transparent material to check the state of the fuse, the element In the case of the inside of the housing and without contacting the housing and the cover, it may be composed of a blown portion that is caused to rise and melt (or melt) when the temperature rises when an overcurrent flows.
- the load 102 that is, the load 102 connected to the rear end of the slow blow fuse 103 according to the present invention, may be any one of a lamp installed in a boom or a cap, a wiper motor, a fan motor, and an equipment controller. Can be.
- a slow blow fuse 103 is provided between a high capacity fuse 101 and a load 102 having a rated capacity higher than the rated capacity of a normal fuse installed according to the load capacity.
- the present invention provides a slow blow fuse 103 at a rear end of the fuse so that an overcurrent exceeding the maximum designed capacity flows through the slow blow fuse 103. It is a system to prevent dangers such as fire that can occur additionally by letting out.
- the slow blow fuse 103 may include, for example, an element made of metal so that electricity may flow, a housing for fixing the element, a cover made of a transparent material to check the state of the fuse, and the element.
- an element made of metal so that electricity may flow
- a housing for fixing the element a cover made of a transparent material to check the state of the fuse
- the element In the case of the inside of the housing and without contacting the housing and the cover, it may be composed of a blown portion that is caused to rise and melt (or melt) when the temperature rises when an overcurrent flows.
- FIG 3 is a view illustrating a slow blow fuse as an example of the present invention.
- the slow blow fuse (Slow blow fuse) usable in the present invention is a small fuse developed in the glass tube or chip type in the form that can be mounted on the PCB can not be easily changed by the user, not a professional It can be misused if the user changes it easily.
- the slow blow fuse usable in the present invention is installed in an electric circuit such as an automobile or an industrial machine to prevent damage and fire of equipment due to overcurrent.
- the slow blow fuse should not be melted at an overcurrent of about 110% or less with respect to the rated current, and if more overcurrent is applied, it should be safely melted within a time that meets the criteria according to the ratio of the overcurrent and at the same time, there should be no risk of fire.
- the slow blow fuse according to the present invention (going out later than the normal fuse) is installed between the fuse and the load, and from the risk of damage to the wiring and the risk of fire caused by electrical overload due to fuse misuse and incorrect circuit change. Protect the equipment.
