Description

Power supply wiring module and automatic transfer switch electric appliance with same

Technical Field

The utility model relates to an automatic change over switch technical field, concretely relates to power connection module and have its automatic change over switch electrical apparatus.

Background

An automatic Transfer Switching apparatus, namely atse (automatic Transfer Switching equipment), is mainly suitable for an emergency power supply system with rated voltage of no more than 1000V of alternating current or no more than 1500V of direct current. In the GB/T14048.11 standard, a transfer switch is defined as: an appliance for switching one or more load circuits from one power source to another; the Automatic Transfer Switching Equipment (ATSE) is as follows: an appliance consisting of a transfer switch appliance (or appliances) and other necessary appliances for monitoring the power circuit and automatically transferring one or more load circuits from one power source to another. That is, between two power supplies, one power supply meeting the standard is selected to continuously supply power to the load, which is the most basic function of the ATSE.

The types of automatic transfer switching devices (hereinafter referred to as "switches") on the market at present are classified into the following two types according to the distribution of a power connection terminal I and a power connection terminal II:

1. the automatic transfer switching device with the structure is called a two-side automatic transfer switching device (for short, a two-side switch), namely the power connection terminal I is placed on one side, and the power connection terminal II and the load connection terminal II are placed on the same side (as shown in figure 1), namely the power connection terminal I and the power connection terminal II are arranged on two sides of the automatic transfer switching device. The main defects of the two-side switches are mainly concentrated on that the space occupied by one-time wiring of the power supply II is large, the consumption of cables or copper bars is large, the processing time of the copper bars is long, the size requirement of the copper bars is strict, the waste of the copper bars is large when the copper bars are scrapped and the user performs one-time wiring once the size of the copper bars is deviated during the wiring, the sizes of the one-time wiring rows between the poles of the two-side switches I and II and between the poles of the load end are different, the wiring time is consumed during the; the installation space occupied by the primary wiring of the different-side switch is large, and the waste caused by the installation of the electric elements of the complete cabinet body is caused. The two-side switch has the advantages of reliable operation, high use category and high technical index of main circuit contact parameters.

2. The power connection terminal I and the power connection terminal II are arranged on the same side of the automatic transfer switching device, the load connection terminal is arranged on the other side (as shown in figure 2), and the automatic transfer switching device with the structure is called as a same-side automatic transfer switching device (hereinafter referred to as a same-side switch). The power supply contact system I and the power supply contact system II of the same-side switch are generally combined together as a whole, and the structures of the power supply contact system I and the power supply contact system II are related to each other, restricted with each other and compact. The use category and the technical index of the contact parameter are not as good as those of the automatic transfer switching equipment at two sides.

In summary, the automatic transfer switching devices with the two structures do not belong to the same type of switch, that is, the switches on the same side and the switches on two sides are relatively independent, and a user can only select one type of the automatic transfer switching devices when selecting or using the automatic transfer switching devices. The two distribution structures cannot be simultaneously realized on the same switch for the user to select. If a user installs the switches on the two sides and finds that the switch selection is improper or the space of one-time wiring is not enough, one-time wiring on the two sides needs to be changed into one-time wiring on the same side temporarily. At present, the automatic transfer switch electric appliance on the market causes the following confusion for users, the installed switches on two sides are disassembled and returned to a manufacturing factory, corresponding cost is borne, and the manufactured wiring copper bar or cable is scrapped. The new ipsilateral switch is re-ordered, again consuming the ordering cycle, time cost and labor cost of one line production. In view of the situation, it is worth to search and explore whether two-in one-out (i.e. two wiring modes of the same product) can be realized on the basis of not changing or damaging the structure of the automatic change-over switch electric appliance on two sides.
