Problems solved by technology

Although this application scheme can meet the requirements of high working voltage, often the wiring at the terminal in engineering applications will not follow the length of 2m specified in 8.3.3.3.4 of GB 14048.2, which will increase the heat accumulation here, and the heat After the heat is transferred to the inside of the circuit breaker, it directly affects the long-delay action characteristics of the long-delay release using bimetallic strips

Abstract

The invention provides a multi-break circuit breaker. A preset connecting mode is adopted. In an insulating shell, every two adjacent groups of movable contacts are connected by a conductor, or a group of movable contacts and static contacts corresponding to the adjacent group of movable contacts are connected by another conductor; after connection in any mode, poles which are provided with at least two breaks connected in series and are homopolar and cophasal are formed; and two groups of movable contacts can rotate independently relative to an insulating rotary shaft. A plurality of breakpoints are connected in series in the circuit breaker shell, and a user does not need to connect wires at wiring terminals independently in order to connect the breaks in series. The long time-delay characteristic also is set under the mode of preset connecting wires, and the acting characteristic of the multi-break circuit breaker is not influenced when the multi-break circuit breaker is used by the user.

Description

technical field [0001] The invention relates to a molded case circuit breaker, which belongs to the field of low-voltage electrical appliances. Background technique [0002] With the development of new energy technology, higher requirements are put forward for low-voltage electrical components. Especially with the continuous development of photovoltaic power plants, the performance indicators of the protection components required by the power plant have higher requirements. For example, in the photovoltaic power DC system, the rated operating voltage of low-voltage electrical appliances has reached DC1500V. Using the method of breaking points in series can improve the breaking performance of the circuit breaker. In this regard, many manufacturers at home and abroad have also introduced various circuit breaker wiring application schemes. Wiring is performed at the external terminal of the circuit breaker, so that two or more poles of the circuit breaker are connected in seri...
