| 发明名称 | Compact switchgear for an electrical consumer | ||
| 摘要 | A switchgear includes a power supply built into a common housing, and at least two drives. The power supply can be fed by an external supply voltage and an external consumer can be connected to the two drives. In at least one embodiment, the switchgear includes, in the same housing, a built-in overload detection for the two drives and/or a built-in circuit breaker function for the two drives, and/or a built-in control circuit for the common control of the two drives. The switchgear can optionally be completed by a transformer providing an additional function of the targeted charging of a buffer capacitor and/or by an energy accumulator providing an additional function of the targeted discharge thereof by temporarily switching on a connected consumer. | ||

| 主权项 | 1. Switchgear, comprising: a power supply integrated into a shared housing; a capacitor configured to store electrical energy; at least two drives, the power supply being suppliable with an external supply voltage and an external consumer being connectable to the at least two drives, at least one of the at least two drives being configured to drive the external consumer in a first operation mode and at least one other of the at least two drives being configured to drive the external consumer in a second operation mode, the first operation mode having a different effect on the external consumer compared to the second operation mode; and at least one switch configured to, when the external consumer is switched off, cause the capacitor to supply the stored electrical energy to the power supply, wherein one of the at least two drives is configured to be activated by a control circuit connected downstream from the power supply by a supply voltage being fed over supply voltage lines in operation to the external consumer, andat least one of the supply voltage lines and each of the supply voltage lines is assigned a transformer which is effective in operation for charging the capacitor connected downstream from the control circuit. | ||
