Embodiment Construction
[0023] An uninterruptible power supply wiring system for negative control equipment, which is used to automatically switch between the main power supply and the backup power supply to realize uninterrupted power supply during equipment maintenance, user power down, and equipment trip recovery operations, including the junction box, in the junction box There is a switching circuit inside.
[0024] Such as figure 1 As shown, the housing of the junction box is a square three-dimensional structure, matrix-type terminal posts 2 are evenly arranged on the upper and lower sides of one side of the housing, and a groove 4 is arranged in the middle of one side, and in the groove 4 The shorting piece 3 and the binding post 2 are evenly arranged, and in order to prevent accidental electric shock, a protective cover 5 is arranged on the groove 4, because the shorting piece and the energizing spring will generate heat when energized. Such as figure 2 As shown, in order to facilitate heat...

The invention provides an uninterruptible power connection system of load control equipment. The uninterruptible power connection system comprises a junction box, wherein a switching circuit is arranged in the junction box; a shell of the junction box is of a square three-dimensional structure; matrix-type binding posts are uniformly arranged at the upper side and the lower side of one side surface of the shell and grooves are arranged in the middle part of one side surface; shorting sheets and binding posts are uniformly arranged in each groove; one side of each shorting sheet is fixed to the corresponding binding post through a bolt and the other side is movably connected with the corresponding binding post; an electrifying spring is arranged at the outer side of each shorting sheet, one end of each electrifying spring is connected with a box body of the junction box at the upper part of the corresponding groove and the other end of each electrifying spring is connected with a free end of the corresponding shorting sheet; a reset spring is arranged at the inner side of each shorting sheet, one end of each reset spring is connected with the free end of the corresponding shorting sheet and the other end of each reset spring is connected with the binding post connected with the free end of the corresponding shorting sheet; and a protective cover is arranged on the grooves. According to the uninterruptible power connection system of the load control equipment, uninterruptible power supply to a user is achieved under the conditions of electrical equipment maintenance and the like.
Description
technical field [0001] The invention relates to the technical field of negative control equipment wiring, in particular to a negative control equipment uninterruptible power wiring system. Background technique [0002] The power load management terminal and the master station system can automatically collect, store, and remotely transmit electricity meter data such as electricity, demand, voltage, current, power, power factor, and voltage qualification rate of large users, so as to realize the power consumption of large users. Statistics, providing all kinds of electricity settlement data for the power marketing system, controlling and managing the load of large users, realizing the orderly consumption of electricity by "cutting peaks and adding valleys", monitoring the operation status of electric energy meters of large users in real time, and detecting abnormal power consumption, Real-time monitoring; combined with the gateway metering automation system and distribution mo...
