Its structure consists of cabinet body, circuit breaker, disconnector, grounding switch, lightning arrester, voltage transformer, current transformer, instrument, relay protection device and other components. The cabinet body has good mechanical strength and insulation performance. The interior is divided into high-voltage chamber and low-voltage chamber, which are used to separate high-voltage equipment and low-voltage equipment. The circuit breaker is used to control and cut off the circuit to protect electrical equipment and lines from overload, short circuit and other faults. The disconnector is used to isolate and cut off the circuit, the grounding switch is used to perform grounding operations, and the lightning arrester is used to protect the circuit from overvoltage. The voltage transformer and current transformer are used to measure the voltage and current values in the circuit to provide accurate electrical parameter data for the relay protection device. At the same time, it is equipped with various instruments to display the voltage, current, power and other parameters of the circuit. The relay protection device is used to monitor the operating status of the circuit. Once a fault occurs, it can cut off the circuit in time to protect the equipment and lines from damage.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-6The utility model provides an embodiment: an improved high-voltage outlet cabinet, comprising a high-voltage outlet cabinet body 1 and a U-shaped vertical rail 2 with a folded edge installed at the corner position of the bottom wall of the high-voltage outlet cabinet body 1, the top ends of the four U-shaped vertical rails 2 are fixedly connected to the top wall of the high-voltage outlet cabinet body 1, and at least one bearing platform 4 is slidably installed on the four U-shaped vertical rails 2. Positioning ribs 3 are fixed on the surfaces of the two U-shaped vertical rails 2 in the same X-axis direction, and a plurality of equally spaced limiting holes 301 are provided on the outer walls on the opposite sides of the two positioning ribs 3. A screw rod bidirectional sliding mechanism 5 is installed at the bottom end of the bearing platform 4, and the two movable ends of the screw rod bidirectional sliding mechanism 5 are installed with anti-drop pins 6 that are plugged into the limiting holes 301;

[0021] At least two longitudinal beams are installed between the two U-shaped vertical rails 2 in the same Y-axis direction. By adding longitudinal beams between the U-shaped vertical rails 2, the weight on the load-bearing platform 4 can be effectively dispersed, thereby reducing the load on each support point;

[0022] The left and right outer walls of the carrying platform 4 are both provided with grooves 401 that slide with the U-shaped vertical rail 2. When the carrying platform 4 slides with the U-shaped vertical rail 2, the grooves 401 ensure that the carrying platform 4 and the U-shaped vertical rail 2 slide stably, preventing the carrying platform 4 from slipping off the U-shaped vertical rail 2.

[0023] The screw bidirectional pushing mechanism 5 includes a hollow frame housing 501 fixed to the bottom end of the supporting platform 4, a bidirectional screw rotatably mounted inside the hollow frame housing 501, a rotary driving member provided at the bottom end of the hollow frame housing 501 for driving the bidirectional screw to rotate, and a nut pair installed at the threads at both ends of the surface of the bidirectional screw, a C-shaped slider 503 being installed on the surface of the nut pair, and an anti-drop pin 6 being installed on the C-shaped slider 503;

[0024] The rotary drive member is a knob 502 rotatably mounted on the bottom end of the hollow frame shell 501 and a right-angle bevel gear transmission structure mounted on the top end of the knob 502 for driving the bidirectional screw to rotate;

[0025] In the process of adjusting the height of the supporting platform 4, the user only needs to perform a twisting action by utilizing the knob 502, the hollow frame housing 501, and the right-angle bevel gear transmission structure and the bidirectional screw rod inside the hollow frame housing 501, so that the installation and maintenance personnel can more easily perform the inspection and maintenance work of the equipment.

[0026] The anti-slip pin 6 includes a convex plate 601 fixed on the surface of the C-shaped slider 503 and a pin rod 602 fixed on the outer wall of one side of the convex plate 601. The outer diameter of the pin rod 602 is equal to the diameter of the limiting hole 301. When the staff manually turns the knob 502, the rotational power of the knob 502 is transmitted to the bidirectional screw rod through the right-angle bevel gear transmission structure inside the hollow frame shell 501, and the bidirectional screw rod drives the nut pair and the C-shaped slider 503 to slide, so that the C-shaped slider 503 drives the convex plate 601, the pin rod 602 and the limiting hole 301 to be plugged in, thereby ensuring that the support platform 4 remains stable at the required height position, avoiding accidental slippage or falling off, and improving the working safety and stability of the equipment inside the cabinet.

[0027] When the embodiment of the present application is in use, the staff first manually slides the supporting platform 4 up and down. During this process, the supporting platform 4 slides relative to the four U-shaped vertical rails 2 until the supporting platform 4 slides to the required height position. At this time, the staff manually operates the screw rod bidirectional sliding mechanism 5, and the two movable ends of the screw rod bidirectional sliding mechanism 5 both drive an anti-slip pin 6 to slide in the X-axis direction, and then the two anti-slip pins 6 move away from each other until the end of the anti-slip pin 6 is inserted into the limiting hole 301 of the positioning rib 3, and then the supporting platform 4 is locked and suspended, and the internal area of the high-voltage outlet cabinet body 1 above the supporting platform 4 can be powered. The gas equipment is arranged, and then another bearing platform 4 is slid and adjusted until the upper and lower spacing between the two bearing platforms 4 can be used for the installation and arrangement of the electrical equipment, and locked according to the same steps. By adjusting the height position of the bearing platform 4 inside the outlet cabinet, it can be adjusted according to the size of the specific equipment to ensure that the equipment is installed firmly and the layout is reasonable, so as to flexibly adapt to the installation needs of electrical equipment of different sizes and shapes, and by flexibly adjusting the spacing between the bearing platforms, the space inside the outlet cabinet can be maximized, so that more electrical equipment can be arranged inside the high-voltage outlet cabinet body 1 for expanded use.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
