The traditional circuit breaker has two operation modes, one is a split-phase operation mode of one operation mechanism in each phase and a three-phase electric appliance linkage mode, and the other is a three-phase mechanical linkage mode of one operation mechanism in three phases. The operating mechanism of the circuit breaker is divided into a hydraulic spring mechanism and a spring operating mechanism. Taking the spring operating mechanism as an example, the secondary control part of the spring operating mechanism consists of a motor energy storage control loop, a heater control loop, a switching-on and switching-off control loop, a standby switching-off control loop, a non-full-phase operation protection control loop, an output signal node and the like.
The secondary control part of the existing circuit breaker operating mechanism mainly has the following problems:
the number of terminals is large: along with the improvement of the performance requirements of users on products, the number of the terminal blocks of the circuit breaker is increased more. For example: the user requires that each terminal can only be connected with one wire, the normally open points and the normally closed points of the auxiliary switches are all connected to the terminals, and the cables are arranged in an alternating current-direct current partition mode. These requirements add nearly 20% to the terminals. The conventional secondary terminal is more than 670, which causes the wiring scheme to be too complex and increases the difficulty of construction and inspection. The wiring terminals of the centralized control part reach 310 pieces, the wiring of each terminal needs to be numbered, and if wiring errors occur or a mechanism is replaced, the workload is high, and errors are easy to occur. And when the problems of loose wiring, virtual connection, aging of components and parts and the like occur, the reason can be difficult to analyze and search, the maintenance and the replacement are not facilitated, and the stability is poor.

Detailed Description
The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
The embodiments of the present disclosure are described below with specific examples, and other advantages and effects of the present disclosure will be readily apparent to those skilled in the art from the disclosure in the specification. It is to be understood that the described embodiments are merely illustrative of some, and not restrictive, of the embodiments of the disclosure. The disclosure may be embodied or carried out in various other specific embodiments, and various modifications and changes may be made in the details within the description without departing from the spirit of the disclosure. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The control cabinet of the high-voltage circuit breaker operating mechanism comprises a plurality of functional modules and bases corresponding to the functional modules. The relay and the contactor in the prior art are eliminated, and only nodes of the travel switch and the auxiliary switch are reserved. The base is installed in the switch board. The functional module is provided with a terminal, a terminal socket is arranged on the base, the terminal is inserted into the terminal socket of the corresponding base, and the functional module is fixed on the base through a screw, so that the functional module is electrically and mechanically connected with the control cabinet.
The functional modules include but are not limited to an energy storage control module, a temperature and humidity control module, a switching-on/off operation module and a non-full-phase protection module.
The wiring encapsulation of each functional module is inside functional module, and functional module pegs graft on the base, realizes being connected with the switch board. The control cabinet is connected with the operating mechanism through the aviation plug, wiring of the control cabinet is directly completed before the control cabinet leaves a factory, only the control modules are required to be plugged when the operating mechanism is replaced on site, and then the control cabinet is connected with a new operating mechanism through the aviation plug without disconnecting and wiring, so that the circuit structure is simplified, the wiring quantity is reduced, the wiring workload is reduced, and the failure rate of an electric appliance is reduced. The control cabinet has higher reliability and can normally work under the conditions of high temperature and high humidity.
Further, when the functional module is replaced, in order to prevent the functional module from being inserted in a wrong direction, the following scheme can be implemented, as shown in fig. 2:
one is that on the functional module and the base shell, a mark with an arrow is designed, which is convenient for the operator to visually confirm the direction when installing. As shown in fig. 2, a mark with an arrow is arranged at the bottom of the functional module, and a mark with an arrow is also arranged on the upper surface of the base corresponding to the functional module, so that when an operator installs the functional module, the operator can prevent the wrong insertion direction as long as the directions of the two arrows are consistent. The specific form of the mark is not limited, and the mark can be relief or a label attached with the mark.
The other is that more than two terminals of the functional module are designed to be different in size, and more than two terminal sockets of the base corresponding to the functional module correspond to the terminals of the functional module. As shown in fig. 2, the two terminals a and b of the functional module are different in size or length. The base corresponding to the functional module is provided with two terminal sockets c and d, wherein the terminal a corresponds to the terminal socket c, and the terminal b corresponds to the terminal socket d. When inserting conversely in the use, the structure hinders and leads to unable normal the inserting, avoids inserting conversely and brings the risk.
Furthermore, in order to prevent the functional module from being plugged into the base which does not correspond to the functional module, a plurality of holes are formed in the bottom of the functional module, a plurality of holes are also formed in the top of the base which corresponds to the functional module, and the holes in the bottom of the functional module correspond to the holes in the base in position. The anti-misplug pins which can be freely matched with the holes are respectively installed in the holes at the bottom of the functional module and the holes on the base in a staggered mode. The only matching of the functional module and the base is realized through different combinations of the error-proof pin positions.
The staggered installation means that the number of the anti-misplug pins less than or equal to the number of the holes are randomly installed in the holes at the bottom of the functional module, the anti-misplug pins are not installed in the holes on the base corresponding to the holes at the bottom of the functional module with the anti-misplug pins installed, and the anti-misplug pins are installed in other holes on the base.
Examples are as follows:
the holes at the bottom of the functional module are numbered as 1, 2, 3 and 4, and are respectively corresponding to the holes 1 ', 2', 3 'and 4' on the base, and 4 misplug prevention pins are arranged. If a misplug prevention pin is installed in the hole 1, the corresponding hole 1 'is not installed, and one misplug prevention pin is installed in each of the holes 2', 3 'and 4'. If one anti-misplugging pin is installed in each of the holes 1 and 2, the corresponding hole 1 ', 2' is not installed, and one anti-misplugging pin is installed in each of the holes 3 'and 4'. The installation positions of the misplug prevention pins of different functional modules are different, so that the misplug prevention pins of the functional modules can be prevented from being positioned in a misplug manner.
