Abstract
The utility model relates to a residual current circuit breaker which comprises the following components: a cover, a base, an explosion chamber which is provided on the base, an operation mechanism, a handle, an electrical release apparatus, a zero sequence current transformer, a junction block and a protective cover, wherein the handle is composed of a gripping part and a sliding part. The handle is provided below the cover. The cover is provided with a through groove for exposing the gripping part of the handle. The operation mechanism is provided below the handle and form a linking connection. The cross section of the sliding part of the handle is arc. The cover is made to a transparent housing and has uniform wall thickness. An arc guiding surface is formed at the inner wall of the cover at a position which is corresponding with the sliding part of the handle. The sliding of the sliding part of the handle is guided through the guiding surface. The cover of the utility model is manufactured to the transparent housing. The intuitive mastering of a user or an electrician to the operation state in the residual current circuit breaker is facilitated. Furthermore the arc guiding surface on the cover guides the sliding of the sliding part of the handle. More reliable sliding of the handle is ensured when the circuit breaker is switched off.
Description
Technical field
The utility model relates to a kind of residual current circuit breaker.
Background technology
The lid of existing residual current circuit breaker is not a transparent shell, so user or electrician can't grasp the working condition of residual current circuit breaker inside intuitively, and whether for example having closes a floodgate puts in place or tripping operation is not arranged.The slipping part of the handle in the residual current circuit breaker is arranged on the below of lid and is connected with operating mechanism, but there is not guiding mechanism in the slipping part of lid and handle, and when closing a floodgate, the slippage of handle is not very reliable.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of residual current circuit breaker of better reliability is provided.
For achieving the above object, the utility model adopts a kind of residual current circuit breaker, comprise lid, base and be arranged on arc control device, operating mechanism, handle, release, zero sequence current mutual inductor, junction block, protective cover on the base, wherein handle is made up of grip part and slipping part, handle places the below of lid, offer the groove that exposes for the grip part of handle on the lid, operating mechanism is arranged on the handle below and constitutes and is connected, and the cross section of the slipping part of handle is circular arc; Lid adopts transparent shell, and the wall thickness of lid is even, forms the spigot surface of circular arc in the slipping part position of the corresponding handle of inwall of lid, and the slippage that forms the slipping part of handle by this spigot surface constitutes guiding.
Lid of the present utility model adopts transparent shell, is convenient to the working condition that user or electrician grasp residual current circuit breaker inside more intuitively.And the slippage that the spigot surface of the circular arc on the lid forms the slipping part of handle constitutes guiding, and when guaranteeing to close a floodgate, the slippage of handle is more reliable.
Description of drawings
Fig. 1 is the utility model embodiment front view.
Embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of residual current circuit breaker, comprise lid 1, base 2 and be arranged on parts such as arc control device on the base 2, operating mechanism, handle 3, release, zero sequence current mutual inductor, junction block, protective cover, wherein lid 1 adopts transparent shell, the wall thickness of lid 1 is even, offer the groove that exposes for the grip part 31 of handle 3 on the lid 1, handle 3 is made up of grip part 31 and slipping part 32, and the cross section of the slipping part 32 of handle 3 is circular arc; Handle 3 places the groove below of lid 1, forms the spigot surface 11 of circular arc in slipping part 32 positions of the corresponding handle 3 of inwall of lid 1, and the slippage that forms the slipping part 32 of handle 3 by this spigot surface 11 constitutes guiding.Operating mechanism is arranged on handle 3 belows and constitutes and is connected.
