Description
Technical field
The utility model relates to a kind of protector that is used for the overvoltage protection on the main frame.
Background technology
Protector must meet the barrier propterty index in the industry standard.Again the overvoltage and the over-current protection criterion of acceptability of protector have been stipulated recently in the new industry standard of issue, wherein require protector when power line touches that load is 40 Ω and 10 Ω in the test, the outside line input of protector should be opened a way and sent lasting visible alarm signal in 3 minutes.In existing protector, the failure protection device of a lot of protectors generally adopts low-melting alloy as the inefficacy material, utilize the low-melting alloy melted by heat to make the slide mechanism action, though they all can send lasting alarm signal when load is 40 Ω and 10 Ω, can not open a way the outside line input.In addition; some protector utilizes fuse-wires structure to accomplish 40 Ω and 10 Ω outside line input open circuit, but does not accomplish to continue alarm when 10 Ω, and; utilize fuse-wires structure usually can exist when fuse failure abating protection device also to have little time action, can not send the situation of alarm signal.
At present, employing thermal deformation metal material (thrermostatic bimetal-plate or memorial alloy) or the thermosensitive magnetism material self-resetting type protector as the inefficacy material is also arranged, they utilize thrermostatic bimetal-plate temperature distortion or thermosensitive magnetism material reduced by thermomagnetion and form the action of threading off, allow d/d slide block back down the inlet wire shell fragment and do not contact, thereby make outside line input open circuit with the inlet wire stator.Though having overcome above-mentioned protector, they can not exist the deficiency of outside line input open circuit higher cost increase, thermal deformation metal material and the temperature-sensitive magnet profile of making of price of thermal deformation metal material and temperature-sensitive magnet need do to such an extent that the problem that takes up room and increase is installed than ambassador.
The utility model content
The purpose of this utility model provides a kind of protector that is used for the overvoltage protection of main frame; low-melting alloy piece that its employing price is lower or the less sliding shoe of volume of low melting point plastic piece control move, use the sliding reed that is contained on the sliding shoe to control the folding of service entrance switch, and the existing protector of solution can not make the outside line input open a way, open a way but can not continue to alarm, lost efficacy the higher problem that makes cost increase, inefficacy material profile take up room and increase than ambassador's installation of material price.
In order to achieve the above object, the utility model is achieved in that a kind of protector that is used for the main frame overvoltage protection, comprise the rectangle box body, cover, light cover, be embedded in the contact chip of box body bottom, the left inlet wire that is installed in the box connects reed, right inlet wire connects reed, by sliding reed, slide block, the service entrance switch that the slide block assembly that the alarm reed is formed constitutes, discharge tube is installed in a left side, right inlet wire connects between reed and the heat conduction grounding reed, reed is drawn in alarm, and to be connected reed with signal by light-emitting diode continuous, and the heat conduction grounding reed is exerted pressure by spring with ground strip and is connected; Its architectural feature is: be provided with the service entrance switch that five groups of slide block assemblies of being made up of sliding reed, slide block, alarm reed constitute in the protector side by side; In each assembly, low-melting alloy piece or low melting point plastic piece are set between slip front and the heat conduction grounding reed, the alarm reed is installed in the slide block rear end; Sliding reed is installed in the bottom surface of slide block or/and the side.
Described slip front has square groove, and low-melting alloy piece or low melting point plastic piece are set in the groove; Have rectangular slot in the middle of the slide block, the alarm reed can be connected with the walking and the heat conduction grounding reed of slide block; The slide block left and right sides has the dovetail groove that communicates with the bottom, and sliding reed embeds in the dovetail groove.Described length of spring compressed connects between the reed at alarm reed and alarm.The rear end of described slide block has dovetail groove, and an end of alarm reed and spring is arranged in the dovetail groove.Described light-emitting diode is independent one or five and is installed on the box body in groups.
The utility model advantage compared with prior art is: because the left and right sides and the bottom of slide block are equipped with sliding reed, can low-melting alloy piece or low melting point plastic piece melted by heat, slide block during to front slide the original input open circuit of connecting, alarm reed simultaneously and connect with the heat conduction grounding reed in the rectangular slot in the middle of the slide block with the walking of slide block, the input open circuit also can send lasting alarm signal during the protector protection.Simultaneously, be the inefficacy material owing to adopt lower low-melting alloy piece or the low melting point plastic piece of price, reduced cost; Because low-melting alloy piece or the low melting point plastic piece can be done lessly, the slide block structure compact volume is less can reduce the installing space that takies.
