Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of test equipment, in particular to a switch electrical appliance testing device. Background Art
[0002] Switching devices are usually used to control the connection and disconnection of electric current. Such devices usually have one or more switches that can turn the current on or off through manual operation or automatic control. Switching devices play a very important role in power systems. They can control the direction and size of the current, thereby controlling the start and stop of electrical appliances and protecting electrical appliances from faults such as overload and short circuit.
[0003] Common switching devices include circuit breakers, disconnectors, load switches, contactors, etc. These devices are usually used in power distribution systems, motor control, lighting systems, etc. Circuit breakers are switching devices that can automatically cut off the circuit. They are usually used in power distribution systems to protect the circuit from overloads and short circuits. Figure 8 As shown, the circuit breaker 7 is generally provided with a handle 71 and a plurality of buttons 72. The handle 71 is a device for opening or closing the circuit breaker. By moving the handle up and down, the circuit breaker can be switched between the open state and the closed state. The button 72 can be divided into a test button and a reset button according to different functions. When the test button is pressed, a leakage current is generated in the circuit to test whether the circuit breaker can be disconnected normally. After the circuit breaker is automatically disconnected due to the leakage current, the reset button needs to be pressed so that the circuit breaker can be closed normally again.
[0004] In order to ensure the performance and safety of circuit breakers, national standards GB 10963.1, GB 16916.1, GB16917.1 and other documents stipulate various technical requirements and tests, including "mechanical and electrical life test verification", which requires thousands or tens of thousands of cycles of on-off operation of the handle and button of the test product. Circuit breakers need to be verified and tested during the R&D stage, type test, and delivery acceptance to ensure that they meet the standard requirements.
[0005] Among them, for the mechanical and electrical life tests of circuit breakers without overcurrent protection, the circuit breaker is required to be able to perform a sufficient number of operation cycles (including a closing operation and a subsequent opening operation) at the rated current. For example, for circuit breakers with a rated current greater than 32A, the operating frequency should be 120 cycles per hour. In each operation cycle, the circuit breaker should remain in the disconnected position for at least 28s.
[0006] If it is related to manual operation, the circuit breaker should be operated at an operating speed of (0.1±0.025)m / s during the driving process; For the mechanical and electrical life test of the residual current operated circuit breaker (RCBO) with overcurrent protection, the circuit breaker is required to perform sufficient operation cycles under specified conditions. For RCBO with leakage current I>0.010A, the first 1000 operation cycles are manually disconnected, followed by 500 operation cycles using the test device for disconnection, and the last 500 cycles are disconnected with a residual operating current of IΔn at one pole.
[0007] In addition, the RCBO needs to be operated without load. When conducting short-circuit tests on circuit breakers, the circuit breaker is required to be able to perform the specified number of short-circuit operations without endangering the operator or causing flashover between live conductive parts or between live conductive parts and the ground.
[0008] The test equipment used in the prior art for mechanical and electrical life operation tests on circuit breakers and other switching electrical appliances has some technical defects. First, when the handle is opened and closed, its closing path is a single "straight up and straight down", which does not conform to the actual working conditions of circuit breakers and other switching electrical appliances. Secondly, when the handle is opened and closed, there is an impact on the handle, which is easy to damage the handle of the circuit breaker and other switching electrical appliances. Finally, the versatility and functional integration of the test equipment are poor, and different tests require different test equipment, which causes inconvenience in testing.
