TECHNICAL FIELD

[0001] The utility model relates to a kind of power supply tool of circuit breaker connection condition can be quickly identified. BACKGROUND

[0002] Circuit breaker power supply tool is a device that can quickly establish power supply connection with circuit breaker, which is usually combined with circuit breaker testing device for testing functions such as remote opening and closing control of circuit breaker. Circuit breaker power supply tool usually includes multiple conductive plugs that are connected and matched with the wiring ports of circuit breaker.

[0003] The existing circuit breaker power supply tool, when in use, the test personnel need to operate the testing device according to the connection condition of the conductive plug of the circuit breaker and the power supply device and the specific type of the circuit breaker to control the circuit on-off and circuit configuration of the conductive plug. For example, when connected with 1P+N or 2P circuit breaker, two conductive plugs connected with the circuit breaker need to be controlled to be powered on in the testing device, and the circuit configuration needs to be adjusted to L and N phase; when connected with 3P circuit breaker, three plugs need to be controlled to be powered on and the circuit configuration needs to be adjusted to A, B, C phase; and when connected with 4P circuit breaker, four plugs need to be powered on and the circuit configuration needs to be adjusted to A, B, C and N phase. This manual adjustment method is tedious and prone to errors, which affects the efficiency and accuracy of the test. SUMMARY

The conductive plugs include a first conductive plug and a second conductive plug distributed in sequence along the arrangement direction. The base is provided with a first press switch, which is triggered by the circuit breaker when the conductive plug and the circuit breaker wiring port are plugged.

[0006] Based on the above scheme, the power supply tool can be adapted to the power supply connection of 1P+N and 2P circuit breaker. When the wiring port of the circuit breaker and the conductive plug of the power supply tool are plugged, the first press switch is triggered when the circuit breaker moves towards the direction of plugging with the conductive plug of the power supply tool. By identifying the power-on state of the first press switch, it can be identified whether the conductive plug of the power supply tool is connected with the wiring port of the circuit breaker. It can be combined to realize self-identification of the testing device, reducing the operation of the operator.

[0007] Further, the first press switch is arranged at a position corresponding to the first conductive plug, so that when circuit breakers of different sizes are connected, the first press switch cannot be normally pressed and triggered.

[0010] The arrangement of the third conductive plug enables the power supply tool to be adapted to connection of a 3P circuit breaker, and when the wiring ports of A, B and C phases of the 3P circuit breaker are connected to the first, second and third conductive plugs, the second press switch is triggered. By identifying the energized state of the first and second press switches, in addition to identifying whether the power supply tool is connected to the circuit breaker, it can also be distinguished whether the power supply tool is currently connected to a 1P+N or 2P circuit breaker or a 3P circuit breaker, so as to be matched with the corresponding switching circuit configuration of the testing device.

[0011] Further, the conductive plugs further include a fourth conductive plug arranged in sequence along the arrangement direction, one end of the fourth conductive plug is arranged at one side of the base, and the other end of the fourth conductive plug extends away from the base.

[0012] The arrangement of the fourth conductive plug enables the power supply tool to be adapted to connection of a 4P circuit breaker, and when the wiring ports of A, B, C and N phases of the 4P circuit breaker are respectively connected to the first, second, third and fourth conductive plugs, the second press switch is triggered. By identifying the energized state of the first and second press switches, in addition to identifying whether the power supply tool is connected to the circuit breaker, it can also be distinguished whether the power supply tool is currently connected to a 1P+N or 2P circuit breaker or a 3P or 4P circuit breaker, so as to be matched with the corresponding switching circuit configuration of the testing device.

DETAILED DESCRIPTION

[0021] The utility model discloses a power supply tool capable of quickly identifying the connection state of a circuit breaker.Figures 1 to 5 As shown, the base 1 is provided with four conductive plugs arranged at intervals, including a first conductive plug 41, a second conductive plug 42, a third conductive plug 43 and a fourth conductive plug 44 arranged in sequence along the arrangement direction.

[0022] One end of the first conductive plug 41, the second conductive plug 42, the third conductive plug 43 and the fourth conductive plug 44 is arranged at one side of the base 1, and the other end of the first conductive plug 41, the second conductive plug 42, the third conductive plug 43 and the fourth conductive plug 44 extends away from the base 1, for cooperating with the wiring port of the circuit breaker.

[0023] The base 1 is provided with a first press switch 51 and a second press switch 52, the first press switch 51 is arranged at a position corresponding to the first conductive plug 41, and the second press switch 52 is arranged at a position corresponding to the third conductive plug 43.

[0024] In the embodiment, the first press switch 51 and the second press switch 52 are both micro switches as shown, and include a main body 501 and a press end 502. Figure 5 The main body 501 of the first press switch 51 and the second press switch 52 is arranged at the other side of the base 1, the main body of the first press switch 51 is located at a position corresponding to the first conductive plug 41, and the main body of the second press switch 52 is located at a position corresponding to the third conductive plug 43, the press end of the first press switch 51 and the second press switch 52 extends away from the base 1 and is close to the other end of the first conductive plug 41 and the third conductive plug 43 respectively, avoiding mutual interference between the conductive plug and the press switch, and improving the adaptability to circuit breakers of different sizes.

[0025] When the circuit breaker is a 1P+N or 2P circuit breaker, the two wiring ports thereof are connected with the first conductive plug 41 and the second conductive plug 42 respectively, and the first press switch 51 can be pressed and triggered, and the second press switch 52 cannot be pressed and triggered; when the circuit breaker is a 3P or 4P circuit breaker, the second press switch 52 will be pressed and triggered when the power tool is connected with the circuit breaker in addition to the first press switch 51; when the power tool is not connected with the circuit breaker, neither the first press switch 51 nor the second press switch 52 is pressed and triggered. Thus, by identifying the energization state of the first press switch 51 and the second press switch 52, it can be distinguished whether the circuit breaker is connected or not, and whether the connected circuit breaker is a 1P+N or 2P circuit breaker, or a 3P or 4P circuit breaker, so as to cooperate with the test device to turn on or off the power or configure the circuit with corresponding switch as LN or ABCN, and the self-identification of the test device can be realized, reducing the operation of the operator.

[0026] In the embodiment, the four conductive plugs are adopted, so that the power supply tool can be adapted to the connection of 1P+N, 2P, 3P and 4P circuit breakers. In other embodiments, only two conductive plugs and the first press switch 51 can be included, so that the power supply tool can be adapted to the connection of 1P+N and 2P circuit breakers, and the detection of whether the power supply tool is connected to the circuit breaker can be realized. Or only three conductive plugs and the first press switch 51 and the second press switch 52 can be included, so that the power supply tool can be adapted to the connection of 1P+N, 2P and 3P circuit breakers. In addition, the second press switch 52 can further distinguish whether the circuit breaker is a 1P+N or 2P circuit breaker or a 3P circuit breaker.

[0027] In the embodiment, the base 1 is provided with a positioning groove 15 for embedding the conductive plug. After the conductive plug is embedded in the positioning groove 15, the conductive plug is fixedly connected through a screw. The side wall of the positioning groove 15 can prevent the conductive plug from shaking. One end of the positioning groove 15 is provided with a through hole for penetrating the wire, so as to facilitate the wiring of the conductive plug.

[0028] As shown in the Figures 3 to 4 The conductive plug is composed of two parts and is formed by bending a metal sheet. The two parts of the conductive plug each include a support plate 401, a positioning hole 402 arranged at one end of the support plate 401, a conductive contact plate 403 connected to the other end of the support plate 401 and extending in a direction inclined to the one end of the support plate 401, and an arc-shaped plate 404 connected to the end of the conductive contact plate 403 and extending in a direction close to the support plate 401. The positioning hole 402 is fixedly connected to the screw. The support plates 401 of the two parts of the conductive plug are aligned and spliced together. The conductive contact plate 403 extending in an inclined manner makes the front end of the conductive plug present a structure of being narrow at the front and wide at the back. The elastic deformation capability of the conductive contact plate 403 can facilitate the insertion of the conductive plug into the wiring port of the circuit breaker, realize stable and reliable conductive contact, and provide a certain positioning effect, so that the conductive plug is not easy to be pulled out of the wiring port. The arc-shaped plate 404 can prevent the conductive plug from being stuck in the wiring port and facilitate the pulling out of the conductive plug. The conductive plug composed of two parts has a simpler structure, which facilitates the production, processing and assembly.

[0029] The support plates 401 of the two parts of the conductive plug are embedded in the positioning groove 15 and aligned with the positioning holes 402. The two parts are fixedly connected through the screw penetrating the positioning holes 402. The screw can also be used for wiring.

[0030] The above embodiment is only one of the preferred embodiments of the utility model. The usual changes and replacements made by those skilled in the art within the technical scheme of the utility model are included in the protection scope of the utility model.
