Problems solved by technology
[0002] In the process of substation protection transformation, due to the tight load and short power outage time, it is often required to debug the newly modified protection device before the power outage. Static debugging is no problem, but it involves the inspection of the operation box device, because it cannot actually carry the switch. Therefore, it cannot be inspected. After the actual power outage, check the operation circuit of the protection device. Once there is a problem with the device, it will affect the entire power outage plan.

Embodiment Construction
[0052] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0053] The portable three-phase circuit breaker simulation box of the present invention includes a simulation box control panel 10, a tripping and closing working circuit, a circuit breaker signal circuit, and an operation mode switching circuit. The control panel of the simulation box is used for integrated installation of wiring sockets, control buttons, and status indicators that are convenient for operators to operate and manage. In order to provide an empty contact for the protection device to measure the return time, etc., the operation mode switching module realizes the corresponding function by switching the handle to switch to different operation modes.
[0054] Such as figure 1 Shown is the schematic diagram of the control panel of the present invention, the control...

The invention discloses a portable three-phase circuit breaker simulation box, which comprises a simulation box control panel, a tripping and closing working circuit, a circuit breaker signal circuit, and an operation mode switching circuit. The control panel of the simulation box is used for integrated installation of wiring sockets, control buttons, and status indicators that are convenient for operators to operate and manage. In order to provide empty contacts for the protection device to measure the return time, etc., the operation mode switching module realizes the corresponding function by switching the handle to switch to different operation modes. Its main function is to cooperate with the protection device to do the export test and simulate the three-phase disconnection The device operating mechanism is used to test and protect the correctness of the operation box device. At the same time, this device simplifies the operation preparation and steps, does not need to connect the power line, and is suitable for carrying when going out for debugging due to its portable size.
Description
technical field [0001] The invention belongs to the field of electric equipment and relates to a portable three-phase circuit breaker simulation box. Background technique [0002] In the process of substation protection transformation, due to the tight load and short power outage time, it is often required to debug the newly modified protection device before the power outage. Static debugging is no problem, but it involves the inspection of the operation box device, because it cannot actually carry the switch. Therefore, it cannot be inspected. After the actual power outage, check the operation circuit of the protection device. Once there is a problem with the device, it will affect the entire power outage plan. According to the principle of circuit breaker switch, a simple and portable circuit breaker simulation box is made. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simulated three-phase circuit breaker...
