Abstract
The present invention relates to a fixing structure of a shunt breaker for a switchboard. In the fixing structure of the shunt breaker for the switchboard provided with a guide rail which is fixed to the switchboard, a main breaker which is arranged on the guide rail, and a shunt breaker, one side of the guide rail installing and fixing part of the shunt breaker is fixed to the guide rail, the primary side of the shunt breaker is inserted into a main bus to be fixed by screws, the main bus is fixed to a shield, and the shield is positioned on and fixed to the switchboard.
Description
Technical field
The present invention relates to a kind of distribution board, particularly relate to and a kind ofly comprise dish, be fixed on the guide rail on this dish and be installed in main road circuit breaker on the guide rail and the distribution board of shunt circuitbreaker.
Background technology
Fig. 3 represents the fixture construction of existing shunt circuitbreaker.The fixture construction of existing shunt circuitbreaker as shown in Figure 3, guide rail 12 is fixed on the dish 11, main road circuit breaker 13 and shunt circuitbreaker 14 are installed on the guide rail 12.The primary side terminal carries out with electric wire or copper bar the connection of shunt circuitbreaker 14.
But, if adopt as above-mentioned prior art shown in Figure 3, then must carry out distribution after main road circuit breaker and shunt circuitbreaker are installed, ifs circuit quantity increases then weight increase, if because the existence of circuit breaker causes losing the line space then the operability variation.In addition, behind line, dismounting need be unscrewed 1 side terminal of shunt circuitbreaker during shunt circuitbreaker, extracts from the terminal part and carries out after connecting electric wire, if line is too much, then is not easy operation.Under the situation of copper bar distribution, must pull down the copper bar of whole circuit.
Summary of the invention
The present invention proposes in order to solve the prior art problem, and its purpose is to provide a kind of distribution board, as long as by tightening or unscrew 1 side splicing ear of the shunt circuitbreaker of this distribution board, just can easily carry out installation and removal.
To achieve these goals, distribution board of the present invention comprises: dish; Be fixed on the guide rail on the above-mentioned dish; With the main road circuit breaker and the shunt circuitbreaker that are installed on the guide rail;
The one side that the guide rail of above-mentioned shunt circuitbreaker is installed and fixed part is fixed on the above-mentioned guide rail, insert 1 side of above-mentioned shunt circuitbreaker among the main road row and be screwed, above-mentioned main road row is fixed on blocks, above-mentioned block to be positioned be fixed on the above-mentioned dish.
If adopt the fixture construction of shunt circuitbreaker of the present invention, then be screwed because of 1 side of shunt circuitbreaker being inserted among the main row, so only, just can easily carry out installation and removal by fastening or unclamp 1 side splicing ear of shunt circuitbreaker.In view of the above, the operating characteristics of assembling improves.Even the capacity of shunt circuitbreaker increases, row's basal area increases along separate routes, also still can easily carry out installation and removal.And, no longer need to pull down whole circuit copper bars.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the fixture construction of expression shunt circuitbreaker of the present invention.
Fig. 2 (a) and Fig. 2 (b) are the figure of the fixture construction of expression shunt circuitbreaker of the present invention.
Fig. 3 is the figure of the fixture construction of the existing shunt circuitbreaker of expression.
Embodiment
Below, the embodiment of the fixture construction of shunt circuitbreaker of the present invention is described with reference to Fig. 1-Fig. 2.And, in Fig. 1-Fig. 2, annotating duplicate numbers, and omitting repeat specification with a part of subscript.
Fig. 1 is the three-dimensional exploded view of the fixture construction of expression shunt circuitbreaker of the present invention.Fig. 2 is the figure of the fixture construction of expression shunt circuitbreaker of the present invention.Fig. 2 (a) is a front elevation, and Fig. 2 (b) is a side view.
The fixture construction of shunt circuitbreaker of the present invention, shown in Fig. 1-2, the one side that the DIN guide rail of circuit breaker is installed and fixed part 6 is fixed on the guide rail, 1 side of shunt circuitbreaker 4 is inserted among the main circuit row 5 used screw-driving.Main circuit row 5 is fixed on blocks on 7, blocks 7 and is positioned and is fixed on the dish 1.In view of the above, circuit breaker 4 is fixed on the guide rail.
As long as the dismounting of circuit breaker by tightening or unscrew 1 side splicing ear screw of shunt circuitbreaker 4, is slided circuit breaker and just can be pulled down.
If adopt the fixture construction of shunt circuitbreaker of the present invention, use screw-driving because be arranged to that 1 side of shunt circuitbreaker 4 is inserted into main road row 5, so only tighten or unscrew 1 side splicing ear of shunt circuitbreaker 4, just dismounting easily.In view of the above, the good operability of assembling.Even the capacity of shunt circuitbreaker is big, row's basal area increases along separate routes, also still can easily carry out installation and removal.And, do not need to pull down whole circuit copper bars.
Claims (1)
1, a kind of distribution board comprises: dish; Be fixed on the guide rail on the above-mentioned dish; With the main road circuit breaker and the shunt circuitbreaker that are installed on the guide rail; It is characterized in that:
The one side that the guide rail of above-mentioned shunt circuitbreaker is installed and fixed part is fixed on the above-mentioned guide rail, insert 1 side of above-mentioned shunt circuitbreaker among the main road row and be screwed, above-mentioned main road row is fixed on blocks, above-mentioned block to be positioned be fixed on the above-mentioned dish.
