Description
Technical Field
The utility model relates to an arc protector, especially an electric arc testing arrangement of area demonstration.
Background
After the lead is used for a long time, the insulation performance of the lead is reduced due to aging, so that an arc fault is generated during use, and potential safety hazards such as electric leakage or fire hazard exist. In order to realize the detection and protection of the arc problem, a corresponding arc fault detection module is arranged in the circuit breaker at present; when the arc fault detection module detects an arc signal, the circuit board controls the indicator lamp to flash to give an alarm, and when the arc signal reaches a threshold value, the circuit board controls the circuit breaker to trip and protect, so that an electrical fire caused by the arc fault is effectively prevented. On the other hand, still need set up the test button among this arc protector, trigger the circuit board through pressing the button promptly and simulate out the arc signal to whether test arc protector can in time trip and reach the protection effect. Due to the functions, the arc protector needs to be provided with a test button and an indicator light structure on the surface, so that the occupied space on the surface of the protector shell is increased. Therefore, the existing arc testing device for the arc protector has the problem of large occupied space.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electric arc testing arrangement of area demonstration. It can effectively reduce the space occupation of the arc protector.
The technical scheme of the utility model: take electric arc testing arrangement who shows, including the circuit board, be equipped with electric arc fault detection module on the circuit board, the outside of circuit board is connected with contact spring and button spring respectively, and one side of button spring is equipped with transparent material's test button, and one side of test button is equipped with indicating module, and indicating module's illumination direction is towards test button.
In the arc testing device with display, the indicating module is an LED emitter, and the outer side of the LED emitter is connected to a circuit board.
In the foregoing arc testing device with display, a driving groove is provided in the middle of the test button, and one end of the button spring passes through the driving groove and extends to above the contact spring.
Among the aforementioned electric arc testing arrangement of area demonstration, still include the protector casing, test button sliding connection is on the protector casing, and test button's one end extends to the protector casing outside and forms the display part, the indication module lock is connected on the protector casing of test button one side.
In the arc testing device with display, the protector shell is provided with an upper limit part matched with the test button.
Compared with the prior art, the utility model has the advantages that the testing button made of transparent material is matched with the indicating module, so that when the arc protector gives an alarm, the indicating module can reflect the light source to the outside of the protector shell through the testing button, thereby achieving the display effect; under the structure, the test button can play the functions of alarm display and test at the same time, and the occupation of the indicator lamp on the surface space of the protector shell is effectively saved compared with the existing arc protector; through the configuration optimization to the protector casing, then can improve test button's action stability to guarantee the display effect of indicating module to test button. Therefore, the utility model discloses can effectively reduce and occupy arc protector's space.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an exploded view of the present invention;
fig. 3 is a view showing the structure of the connection of the test button and the indication module to the protector case.
The labels in the figures are: 1-circuit board, 2-arc fault detection module, 3-contact spring, 4-button spring, 5-test button, 6-indication module, 7-protector shell, 501-driving groove, 502-display part and 701-upper limit part.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The arc testing arrangement who shows in area constitutes as shown in fig. 1, including circuit board 1, is equipped with arc fault detection module 2 on the circuit board 1, and the outside of circuit board 1 is connected with contact spring 3 and button spring 4 respectively, and one side of button spring 4 is equipped with transparent material's test button 5, and one side of test button 5 is equipped with indicating module 6, and indicating module 6's illumination direction is towards test button 5.
The indicating module 6 is an LED emitter, and the outer side of the LED emitter is connected with the circuit board 1.
The middle part of the test button 5 is provided with a driving groove 501, and one end of the button spring 4 passes through the driving groove 501 and extends to the upper part of the contact spring 3.
Still include protector casing 7, test button 5 sliding connection is on protector casing 7, and test button 5's one end extends to the protector casing 7 outside and forms display portion 502, indicating module 6 lock is connected on the protector casing 7 of test button 5 one side.
The protector shell 7 is provided with an upper limit part 701 matched with the test button 5.
The utility model discloses a theory of operation: when arc fault detection module 2 detects that the circuit has an arc fault, arc fault detection module 2 transmits the signal to circuit board 1, and by circuit board 1 control indicating module 6 scintillation, the light that indicating module 6 scintillation produced is conducted to the display part 502 that is located the protector casing 7 outside through test button 5, makes it can replace original pilot lamp to realize display effect. When testing the arc protector, the operating personnel press the test button 5 first, the test button 5 drives the button spring 4 to press down and make it contact the contact spring 3 through the driving groove 501 after pressing down to realize the circuit intercommunication, and the circuit board 1 triggers and simulates an arc signal after the circuit intercommunication, and then drives the trip of the arc protector, realizes the test effect. Through the cooperation, the test button 5 can realize alarm display and test functions at the same time, so that an original indicator lamp arranged on the protector shell 7 is effectively omitted, and the functionality of the test button 5 and the space utilization rate of the arc protector are improved.
