Description
Technical field
The present invention relates to a kind of protector for electric prospection, more particularly to a kind of current temperature double acting Thermal protection
Device.
Background technology
Protector is widely used in temperature control and the protection of the home electrical heaters such as transformer, motor and similar electrical equipment, it
It can experience and follow the change of environment temperature, and in the cut-out of default temperature spot execution circuit, play control and defencive function.
A kind of existing protector, contains shell, bimetal leaf, stationary contact, bottom plate and junction block one and junction block two.Bottom plate and shell it
Between be provided with insulating paper, junction block one is connected with bottom plate, and stationary contact is arranged on bottom plate, and one end of bimetal leaf is set by rivet
In shell, the other end of double golden shoe is provided with movable contact, and the movable contact that double golden shoe other ends are provided with contradicts and is arranged on bottom
Stationary contact closure on plate, shell and bottom plate are arranged in insulating boot body.During work, when electrical equipment because of heating rises to temperature
During the operating temperature of protector, shell is heated and is conducted to bimetal leaf, and bimetal leaf is heated to be produced internal stress and act rapidly,
Push movable contact open and leave stationary contact and disconnecting circuit, played a protective role so as to cut off appliances power source.When protected electrical equipment temperature
When degree drops to the specified reset temperature value of protector, bimetal leaf returns to the dynamic and static closing of contact of original state, and electrical equipment recovers
Normal work.In above-mentioned protector, the heat in double golden shoe is conducted by shell, because by shell product, heat conduction system
The influence of number and environment, often leads to the slow movement or inconsistency of the heated power-off of bimetal leaf, so as to reduce to electrical equipment
Protecting effect.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of current temperature double acting thermal protector, and the current temperature is double
Effect thermal protector can improve the agility and stability of the heated de-energizing actions of bimetal leaf, electrical equipment is more effectively protected
Shield.
In order to solve the above-mentioned technical problem, a kind of current temperature double acting thermal protector of the invention, contains shell, bimetallic
Piece, stationary contact, bottom plate, junction block one and junction block two, are provided with insulating paper, one end of bimetal leaf passes through between bottom plate and shell
Rivet is arranged in shell, and the other end of double golden shoe is provided with movable contact, movable contact and setting that double golden shoe other ends are provided with
Stationary contact closure on bottom plate, junction block one is connected with shell, and shell and bottom plate are arranged in insulating boot body, also bridge-type electricity
Backing, the bottom plate is Split type structure, and bottom plate includes left plate and right panel, spacing, the junction block are left between left plate and right panel
Two are connected with the left plate of bottom plate, and stationary contact is arranged on the right panel of the bottom plate, and the two ends of bridge-type electric heating piece are separately positioned on institute
State in the left plate and right panel of bottom plate.
The bridge-type electric heating piece is inverted U-shaped, and the top of the bridge-type electric heating piece is relative with the middle part of double golden shoe
Should.
The movable contact and stationary contact are packet structure.
In above-mentioned current temperature double acting thermal protector, due to being connected with bridge-type electric heating on the bottom plate of Split type structure
Piece, therefore during work, the heat that bridge-type electric heating piece is sent directly is radiated on bimetal leaf, is heated so as to improve bimetal leaf
The agility and stability of de-energizing actions, are effectively protected electrical equipment.
