Description
Technical Field
The utility model relates to a leakage protector, in particular to a double-arc-extinguishing cover type leakage protector.
Background
In the traditional leakage protector, a circuit board is directly connected with a wire inlet end through a wire, and when the circuit board detects the leakage problem, an electromagnetic mechanism is driven to drive a release to act so as to mutually disconnect a movable contact and a fixed contact, thereby realizing the leakage protection of the leakage protector; meanwhile, when the leakage protector trips, the power supply of the circuit board is cut off, so that the release is cut off. However, when wiring, an installer often connects the wire inlet and outlet ends in a reverse manner, namely, an external line is connected from the wire outlet end, and an internal line is connected from the wire inlet end, so that when the tripper is opened by leakage current through the circuit board, the tripper cannot be disconnected along with the tripping of the leakage protector, but is continuously electrified to work until the tripper is burnt out, and the service life of the tripper is greatly shortened; meanwhile, the circuit board is in a continuous power-on state, so that large loss is caused.
In order to solve the problem, the current leakage protector is additionally provided with a power taking mechanism between an L pole wire inlet end and a circuit board, so that the power taking mechanism can be driven to be disconnected together by the disconnection action of the leakage protector, and the circuit board is powered off. For example, in patent 202021880008.9, "electricity taking mechanism for circuit breaker", an electricity taking mechanism is provided between two actuators, so that the actuators can operate to separate the moving contact spring and the electricity taking spring from each other, thereby disconnecting the circuit board. Although the structure can realize the disconnection action of the circuit board, in the actual use process, because two contacts can instantly release a large amount of electric arcs and generate sparks when the circuit is disconnected, the contact position can reach 6000 ℃ in a short time. The defects cause that the contact position of the electricity taking mechanism generates high-temperature carbonization due to multiple breakouts of the leakage protector, thereby influencing the electricity connection stability and the leakage protection effect of the circuit board. On the other hand, get electric mechanism and still need connect L utmost point wiring board and circuit board respectively through solitary wire when the installation to the setting of this structure can further increase the complexity of circuit and operating personnel's the wiring degree of difficulty on current earth-leakage protector's basis.
In addition, still need set up test button among the earth-leakage protector, test button can drive the test spring contact and trigger the circuit board and simulate out the electric leakage effect after pressing to whether the earth-leakage switch action of measuring earth-leakage protector is normal. However, the existing test spring is respectively connected with the L pole and the circuit board through two independent wires, so that the circuit complexity of the leakage protector is further increased, more workload needs to be consumed when an operator manually performs wiring, and the assembly efficiency of the leakage protector is reduced.
In order to realize the installation of the structure and complete corresponding wiring, the residual space in the leakage protector can be occupied; the internal space of the earth leakage protector is relatively narrow, so that the structure can further extrude the space of other functional parts and an actuating mechanism after being additionally arranged, and only one arc extinguishing cover can be put down in the existing bipolar earth leakage protector, so that the problem of poor arc extinguishing effect of the earth leakage protector is caused.

The working principle of the utility model is as follows: in the assembly process, the electricity taking part 8 is buckled on the protector shell 1 through the elastic pressing sheet 801 at one end, and then the L-pole electromagnetic system 4 is inserted into the protector shell 1 from one side of the electricity taking part 8, so that the elastic pressing sheet 801 is extruded and deformed after the electromagnetic system is inserted, and the two parts are tightly attached and electrically connected. The handle spring 7 and the button spring 14 are welded with each other and then are installed together with the handle 3, so that the handle spring 7 and the button spring 14 are kept in an electrically connected state when the earth leakage protector is switched on and switched off. When the utility model is electrified, the second electrifying contact 12 of the electricity taking part 8 is mutually attached to the first electrifying contact 10 of the handle spring 7 under the closing state of the handle 3, so that current sequentially flows through the L-pole wiring board, the L-pole electromagnetic system 4, the electricity taking part 8 and the handle spring 7 and then enters the circuit board 6, and the electricity taking effect is achieved.

When the circuit board 6 detects an electric leakage state, the trigger release is ejected out to separate the moving contact and the static contact at two sides from each other and release electric arcs, and meanwhile, the moving contact triggers the actuating mechanism 2 to act after being ejected out, so that the handle 3 rotates from a closing state to an opening state.

Because the linkage action of the actuating mechanism 2 and the opening action of the handle 3 need to consume a certain time, the arc releasing time of the rotating part 9 and the electricity taking part 8 is later than the separating time of the movable contact and the static contact, and then the movable contact and the static contact can release most of arcs before the electricity taking structure is disconnected, namely the arc releasing amount of the rotating part 9 and the electricity taking part 8 is reduced when the rotating part and the electricity taking part are separated, and the problem of high-temperature carbonization of the position of a disconnected contact is solved.
