The invention discloses a novel wiring board for a power distribution cabinet. The novel wiring board comprises a first part and a second part, wherein two connecting plates are symmetrically welded to two sides of each of the first part and the second part and are fixedly connected through a connecting bolt; two alignment rods are symmetrically welded to the upper surface of the second part, three mounting pieces are welded to lower part of the second part in an equal interval manner, and mounting through holes are formed in the surfaces of the mounting pieces; and a plurality of wire clamping slots are formed in one surface, opposite to the second part, of the first part in an equal interval manner, wire clamping boards are connected in the wire clamping slots through clamping springs, the surfaces of the wire clamping boards are arc-shaped structures, and limiting sliding plates are symmetrically welded to two sides of the wire clamping boards. According to the novel wiring board, the wire clamping boards are connected in the wire clamping slots through the clamping springs, so that electric wires in the power distribution cabinet can be stably clamped by virtue of the novel wiring board, and the safety of the novel wiring board is higher.

The invention provides a comprehensive power supply system with a remote monitoring function. The comprehensive power supply system comprises a box, wherein the box comprises a base plate, wall bodies and a top cover, and a high-voltage room, a transformer room, a low-voltage room and an industrial personal computer are arranged in the box; in a box-type substation, the high-voltage room, the transformer room and the low-voltage room are provided with doors and windows, and exhaust fans are arranged on the windows, so that natural ventilation and mechanical ventilation are combined, and maintenance is convenient; the wall bodies and clapboards on the circumference of the substation are respectively provided with inner-layer steel plates and outer-layer steel plates, a cavity is formed between each inner-layer steel plate and outer-layer steel plate, and fireproof sound-insulation cotton is arranged in each cavity; and radiation heat-dissipation cooling coating coats the surface of each outer-layer steel plate. The radiation heat-dissipation cooling coating can radiate object heat and achieve heat-dissipation waterproof functions; and the radiation heat-dissipation cooling coating can automatic radiate the heat of the coated object to an atmospheric space, reduces surface and interior temperature of the box-type substation and also achieves a soundproof function.

An enclosure for electrical equipment is provided. The enclosure includes a frame, a first plate, and a first member coupled to the frame and configured to receive the first plate. The first plate is configured to receive a transformer, movable between a first position and a second position, at least partially supported by the first member when the first plate is in the first position, and offset from the first member when the first plate is in the second position.

A motor control center system is provided. The system includes an electrical enclosure configured to house one or more compartments. The electrical enclosure includes a vertical ground bus adjacent to the one or more compartments. The component unit is removably disposed within a compartment of the electrical enclosure. The system also includes a ground stab system disposed on an exterior surface of the component unit. The ground stab system is configured to operatively couple with the vertical ground bus when the component unit is inserted into the compartment of the electrical enclosure, and the ground stab system includes an alignment bracket configured to align the ground stab system with the vertical ground bus.

The invention relates to the field of temporary grounding, in particular to a temporary grounding device of a distribution box substation and a grounding method. The temporary grounding device of the distribution box substation is characterized in that when discharging is carried out on a phase A, a phase B and a phase C, a discharging caution link is added. The grounding method comprises the following specific steps of (1) carrying out a check to ensure that conductor hanging parts and a wire clamp are reliably connected with a soft copper wire, and insulating rods meet the requirement for insulation; (2) carrying out a check on a live wire according to the requirements of site rules before operation; (3) hanging the first conductor hanging part on a bus of the phase A after the wire clamp is grounded, wherein when a reliable connecting loop is formed by a bus of the distribution box substation and a ground wire, a discharging indication alarm device on the first conductor hanging part can give out sounds with high decibel to low decibel, when sounds are not given out, or the given sounds are intermittent, a hanging point is in poor contact, and discharging of the phase B or the phase C is carried out after discharging of the bus of the phase A is accomplished. Compared with the prior art, the temporary grounding device of the distribution box substation and the grounding method have the advantages that convenience of operation of temporary grounding and reliability of grounding are ensured, and the installing efficiency of the ground wire is improved when an electric power circuit is in outage operation.
