Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a high-voltage PT cabinet. Background Art

[0002] In our daily life, we cannot do without the use of electric energy. Electric energy needs to be transmitted by the power system. In the power system, a high-voltage PT cabinet is generally used, in which a voltage transformer is installed. It is generally directly connected to the busbar to detect the busbar voltage and realize the protection function. In the existing high-voltage PT cabinet, the voltage transformer is generally directly installed on the bottom wall of the cabinet by bolts. Due to the small space inside the cabinet and the inability to change the installation position of the voltage transformer, the maintenance and installation of the voltage transformer are difficult, which affects the convenience of use;

[0003] The existing Chinese patent CN218997359U discloses a high-voltage PT cabinet, in which a handle is pulled forward, and the handle drives the voltage transformer mounting seat to move forward a certain distance, thereby facilitating maintenance and installation;

[0004] The voltage transformer needs to be connected to the circuit before it can be used. Therefore, the voltage transformer installed in the high-voltage PT cabinet needs to be connected to the circuit using wires or cables. The above-mentioned high-voltage PT cabinet only pulls the voltage transformer and does not process the wires connected to the voltage transformer. In this way, when pulling and pushing the voltage transformer, it is easy to cause the wires connected to the voltage transformer to be pulled and entangled with each other, which in turn causes the voltage transformer to be disconnected from the circuit due to loose wires.
