[0002] A low-voltage reactive power compensation cabinet is a device that regulates power through capacitive and inductive loads. Due to the phase difference between voltage and load current, it will cause embedded power consumption, greatly reduce power efficiency, cause waste, cause large voltage fluctuations, and make it difficult to maintain the stability of the power grid.

[0003] In the past, low-voltage reactive compensation cabinets did not have an insulating structure inside to isolate adjacent accessories and electrical components. If external vibrations caused different parts to come into contact with each other, the stable circuit would become disordered, making it very inconvenient and dangerous for electricians to operate.

[0004] Now, a new type of low-voltage reactive power compensation cabinet with good insulation is proposed to solve the above problems. Utility Model Content

[0013] Preferably, the connecting block and the dustproof plate are in the same horizontal plane, and the vertical rod can move up and down along the inner walls on both sides of the vertical groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the low-voltage reactive power compensation cabinet with good insulation not only avoids the parts from contacting each other, realizes the separate operation of the cabinet, but also ensures the ventilation of the cabinet;

[0015] (1) By assembling three sets of mounting plates at the rear of the metal cabinet, the switch is mounted on the first rod, and the top of the rod is provided with a corresponding second rod. The fuse on the surface of the second rod is electrically connected to the switch. When adjusting and connecting the wiring harness, the electrician first lifts the cover and turns the rotary blocks connected at the bottom of both sides for support. After the adjustment, the rotary blocks are removed to close the hinged cover. When closing the lower door panel on the left, the card frame cover coated with an insulating coating can also be connected in front of each mounting plate and accessory to achieve multi-layer insulation protection, which can prevent different accessories from interfering with electrical components.

After locking the lower door panel with a door lock, only the upper door panel can be opened to use the screen and the keypad;

[0017] (3) By staggeredly arranging ventilation grooves on both sides of the lower door panel, the vertical rod is moved in a small range along the vertical groove at the center of the lower door panel. The connecting blocks fixed on both sides of the vertical rod can guide the dustproof plate in the hidden chamber to move, so that the dustproof plate moves upward into the ventilation groove for covering. If ventilation is necessary, the dustproof plate is guided downward to leave the ventilation groove, and the exposed ventilation groove can be used for heat dissipation of the metal cabinet. If it is not necessary, the dustproof cloth is closed to prevent rain and dust from the outside from entering the metal cabinet through the ventilation groove. BRIEF DESCRIPTION OF THE DRAWINGS
