Abstract
The utility model relates to a threephase load balanced control switch cabinet which is realized by a phase control switch (2) of a user having unbalanced electricity consumption to adjust the power supply phase of the lead wire of the user when the throughphase power supply load is not balanced in a threephase AC power supply system. The unbalanced load of the user transfers to other phase wires of the power supply system, thereby reaching the aim of the balance control of the threephase load of the power supply system.
Description
Technical field
The utility model relates to a kind of three-phrase burden balance control switch cabinet of energy Balance Control three-phase load output in three-phase AC electrical supply system.
Background technology
At present, in three-phase AC electrical supply system, as long as equipment and line construction install, after system puts into operation; The supply power mode of this electric power system is just fixing.But along with time, changes of seasons and user's needs, the uneven power supply of three-phase load phenomenon can occur thereupon.Can influence the safe operation of electric power system when serious.The first method that addresses this problem is to improve the design capacity of electric power supply system equipment facility and circuit, but this method can strengthen the construction investment of electric power system, and uneconomical, the wasting of resources phenomenon of system's operation can occur.The second method that addresses this problem is in time to adjust electric power supply system equipment facility and circuit, but this method can cause long power failure and increase a large amount of workloads; After the adjustment also the uneven power supply of new three-phase load phenomenon can appear along with time, changes of seasons and user's needs; So in time adjust also very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of in three-phase AC electrical supply system, when three-phase load uneven power supply occurs and surpasses the phenomenon of allowed band, can in time adjust three-phase power line quickly, make the three-phrase burden balance control switch cabinet of three-phase load population equilibrium output.
The purpose of this utility model is achieved in that the phase place adjustment switch of setting up an energy adjustment change mode of connection but do not change phase sequence on the part or all of circuit of regular tap cabinet.Adjust the phase place that switch can change user's three-phase firewire by phase place, a phase firewire of this user's peak load is received on the phase firewire of supply load minimum in the electric power system.Thereby reach a maximum phase load in the electric power system is shifted the purpose that realizes the output of control three-phase load population equilibrium to a minimum phase load.
The utility model can supply load occur when uneven in electric power system, adjusts switch by phase place quickly and changes user's power supply phase place but do not change the power supply phase sequence; Maximum one phase load that prevents the uneven electricity consumption user of multichannel inserts on the same phase firewire of electric power system simultaneously.Can more reasonable, scientifically utilize the limited resources of electric power system, improve the operational efficiency of electric power system, guarantee the safe operation of electric power system.

Fig. 1 is a front elevation of the present utility model.
Fig. 2 is a phase place of the present utility model circuit diagram when adjusting switch operating mechanism and placing 2 grades.
Fig. 3 is a phase place of the present utility model circuit diagram when adjusting switch operating mechanism and placing 1 grade.
Fig. 4 is a phase place of the present utility model circuit diagram when adjusting switch operating mechanism and placing 3 grades.
Among the figure 1, switch cubicle 2, phase place adjust switch 3, phase place is adjusted switch operating mechanism.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed description.
The utility model is to have set up phase place to adjust switch (2) and phase place adjustment switch operating mechanism (3) on switch cubicle (1).When electric power system three-phase load power supply imbalance occurs and surpasses the phenomenon of allowed band, can adjust switch operating mechanism (3) to the phase place that occurs uneven electricity consumption user in the electric power system and adjust to 1 grade or 3 grades from 2 grades, promptly adjust this user's phase place and adjust the mode of connection of switch (2), make user's the lead mode of connection adjust to Fig. 3 or Fig. 4 state from Fig. 2 state; Thereby realize maximum one phase load minimum phase load in electric power system of uneven electricity consumption user is shifted, finally reach the purpose of Balance Control three-phase load output.
Claims (3)
1. a three-phrase burden balance control switch cabinet is characterized in that having set up phase place and adjusts switch (2) and phase place adjustment switch operating mechanism (3) on switch cubicle (1); Can adjust the mode of connection of switch (2) by the operation change phase place of phase place being adjusted switch operating mechanism (3).
2. three-phrase burden balance control switch cabinet according to claim 1 is characterized in that having set up phase place and adjusts switch (2) and phase place adjustment switch operating mechanism (3) on switch cubicle (1).
