Abstract

The invention discloses a voltage control box used for a breaker puncture test. The voltage control box comprises a voltage regulation circuit, a boosting circuit, a near-end sound and light circuit, a far-end sound and light circuit and a voltage regulation control circuit. The voltage regulation circuit is connected with the boosting circuit and the near-end sound and light circuit respectively. The voltage regulation circuit is connected with the voltage regulation control circuit through an external voltage regulation and limiting motor. Communication between the near-end sound and light circuit and the far-end sound and light circuit is carried out through a Bluetooth device. The near-end sound and light circuit is connected with the input end of the voltage regulation circuit in parallel. The voltage control box can effectively avoid potential safety hazards and personal risks of people, especially other workers not within electric connection ranges not capable of being seen by operators, surrounding the spot due to shouting negligence and lack of monitoring before manual operation. Meanwhile, the voltage control box can carry out constant-speed boosting and constant-speed step-down, thereby eliminating the limitation that operators rich in experience are needed to carry out manual operation and control in the traditional voltage control box boosting process and reducing test difficulty.

Description

technical field [0001] The invention relates to an electrical test equipment, in particular to a voltage control box used for a circuit breaker withstand voltage test. Background technique [0002] The power system includes a large number of electrical equipment, and the failure of some electrical equipment may even threaten the safe power supply of the entire system. The practice of electric power production has proved that testing and testing electrical equipment according to regulations is one of the important measures to prevent problems before they happen and ensure the safe and economical operation of the power system. The so-called "preventive test" is named after this. The test for newly installed and overhauled electrical equipment is called the handover acceptance test. Its purpose is to assess the quality of the electrical equipment itself and its installation and overhaul. The purpose of handover acceptance test and preventive test is the same. According to th...
