Description

Economic fixed partition unit Technical Field The utility model relates to the technical field of power transmission and distribution in the power industry, in particular to an economical fixed separation unit. Background Low voltage fixed-divider switchgear is an important component of power systems and is very widely used. The common low-voltage fixed separation switch equipment in the market is suitable for a power system with more loops, the internal structure of the low-voltage fixed separation switch equipment is relatively fixed in a standard fixed interval, a plug-in circuit breaker and a matched plug-in base are installed on a back plate, the low-voltage fixed separation switch equipment is connected with a bus bar behind a cabinet through a primary bus bar, and once the installation is completed, the position and the configuration of each functional unit are difficult to adjust. If the loop configuration needs to be adjusted, the whole cabinet body is often changed greatly, which is time-consuming and labor-consuming. The breaker is installed by matching the plug-in base and the secondary control element, and compared with some low-voltage power distribution cabinets with simple structures, more materials and more complex processes are used, and the cost is high. The Chinese patent with the bulletin number of CN203103790U discloses a feeder cabinet, which comprises a cabinet body, wherein a pluggable switch is arranged in the cabinet body, and a functional unit installation chamber, a vertical bus chamber and a cable outlet chamber are arranged in the cabinet body. The cabinet body forms a functional unit installation chamber, a vertical bus chamber and an outgoing cable chamber which are sequentially arranged from front to back through the functional unit installation plate and the vertical bus partition plate. The two sides of the functional unit installation chamber are correspondingly provided with a functional upright post respectively, and the functional unit installation plate is connected with the functional upright post. The utility model selects the plug-in type switch for fixed installation, has simple structure, fixed wiring, reliable electrical connection quality, effectively realizes the separation of the cabinet bodies, has good separation form, can effectively prevent the expansion of accidents, and achieves the purposes of miniaturization of the cabinet bodies and effective cost reduction. The utility model has the characteristics of compactness, economy, modularization, high protection and high reliability, and is particularly suitable for customers with smaller power distribution room area and upgrading and reforming power distribution rooms. However, the disclosed scheme has the defects that the scheme is supported and connected through the functional upright post when in use, but the device is difficult to install and complex to operate when in actual use, so that the installation efficiency of the electrical equipment is reduced. Disclosure of utility model This section is intended to outline some aspects of embodiments of the utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section as well as in the description of the utility model and in the title of the utility model, which may not be used to limit the scope of the utility model. The utility model aims at solving the technical problems in the background technology, and provides an economic fixed separation unit, which cancels the plug-in base of a circuit breaker by the device, changes the plug-in type circuit breaker body into a standard fixed board front wiring, the circuit breaker mounting holes with different capacities are reserved on the mounting plates with the same height interval, so that complex holes of the plug-in base can be omitted, the constraint of the plug-in base on the configuration of the circuit breaker can be solved, the flexibility of changing the configuration is improved, and the production cost of the plug-in base and the plug-in circuit breaker is reduced. Through canceling the supporting plug-in base of circuit breaker, change the mounting means of circuit breaker, optimize the structure of mounting panel, improved the flexibility that the distribution circuit interval was disposed, reduced the brand dependence of later maintenance transformation, make the installation simple and convenient, reduce cost.
