Problems solved by technology
The circuit breaker body and wires in the related art are usually fixed with multiple screws. When the inspector needs to disassemble the circuit breaker body, he needs to loosen or tighten the multiple screws separately, which makes the operation more convenient. Poor shortcomings, room for improvement

The invention relates to a voltage and current digital sensor, and relates to the technical field of electrical facilities. The digital sensor comprises a main detector, a lead and an auxiliary detector which are connected in sequence, the main detector is provided with a voltage transformer and a current transformer, and the main detector and the auxiliary detector are respectively provided with a C-shaped mounting frame. Abutting blocks are vertically arranged on the mounting frames in a sliding mode, the abutting blocks and the inner walls of the upper ends of the corresponding mounting frames can jointly clamp an electric wire, and driving mechanisms used for driving the corresponding abutting blocks to move are arranged on the mounting frames. The mounting frames are pushed to move, an electric wire is clamped between each abutting block and the inner wall of the upper end of the corresponding mounting frame, the driving mechanisms drive the corresponding abutting blocks to move upwards, the abutting blocks and the inner walls of the upper ends of the corresponding mounting frames jointly clamp the electric wires, and then the electric wires can be connected with the main detector or the auxiliary detector. According to the design, independent screwing operation does not need to be conducted on the screws, so operation convenience is improved.
Description
technical field [0001] The application relates to the field of electrical facilities, in particular to a voltage and current digital sensor. Background technique [0002] The pole-mounted circuit breaker refers to the circuit breaker installed and operated on the pole. The pole-mounted circuit breaker can change high voltage into low voltage and large current into small current for measurement or protection system. At the same time, wireless signal transmission facilities can also be installed on the existing pole-mounted circuit breaker, so as to convert the electrical signal into a digital signal and transmit it to the control terminal (computer, mobile phone, etc.), so as to realize the digital function of the pole-mounted circuit breaker. [0003] The pole-mounted circuit breaker in the related art needs to be fixedly connected to the electric wire, and the voltage and current in the electric wire are detected by the voltage transformer and the current transformer inside...
