Abstract
The utility model discloses a kind of circuit board of plastic casing formula earth leakage circuit breaker, it relates to breaker technical field.Chip (1) distinguishes early-warning lamp (7), display unit (6) sets up an organization with safety electric flow, and (2) are connected, safety electric flow set up an organization (2) be connected with one end of dropout drive system (3), the other end of dropout drive system (3) is connected with one end of dropout driving element (4), and the other end of dropout driving element (4) is connected with tripping actuating mechanism (5).Circuit board is arranged early-warning lamp and display unit; the current signal of instrument transformer collection in earth leakage circuit breaker directly can be shown by display unit; there is warning light to warn simultaneously; even the situation of electric leakage also can be detected when safety electric flow sets up an organization in the normal range (NR) that arranges like this, be convenient to the timely eliminating of equipment fault.
Description
Technical field:
The utility model relates to a kind of circuit board of plastic casing formula earth leakage circuit breaker, belongs to breaker technical field.
Background technology:
Residual current operated protective device is called for short earth leakage protective device, is earth leakage circuit-breaker again, is mainly used for protecting when equipment generation leak current fault and to there being the person of fatal risk to get an electric shock.At present, plastic casing formula earth leakage circuit breaker on market, comprise pedestal, operating mechanism, thermal element, instrument transformer, circuit board, hot terminal, zero line binding post, arc-extinguish chamber, live wire moving contact, zero line moving contact and stationary contact first-class, there is certain defect in this plastic casing formula earth leakage circuit breaker: circuit board only by the electric leakage signal of instrument transformer collection to realize the power-off protection of equipment, but be not provided with display unit and prior-warning device, and the concrete magnitude of current of instrument transformer collection can not reflect intuitively, can not give the alarm simultaneously and remind people to note, existing earth leakage circuit breaker can not detect the situation of electric leakage in safety electric flow sets up an organization the normal range (NR) that arranges, so just be not easy to the timely eliminating of equipment fault.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of circuit board of plastic casing formula earth leakage circuit breaker.
The circuit board of the utility model earth leakage circuit breaker; it comprises chip 1, safety electric flow sets up an organization 2, dropout drive system 3, dropout driving element 4, tripping actuating mechanism 5, display unit 6 and early-warning lamp 7; chip 1 respectively early-warning lamp 7, display unit 6 and safety electric flow sets up an organization 2 connections; safety electric flow sets up an organization and 2 to be connected with one end of dropout drive system 3; the other end of dropout drive system 3 is connected with one end of dropout driving element 4, and the other end of dropout driving element 4 is connected with tripping actuating mechanism 5.
The beneficial effects of the utility model: it can overcome the drawback of prior art; circuit board is arranged early-warning lamp and display unit; the current signal of instrument transformer collection in earth leakage circuit breaker directly can be shown by display unit; there is warning light to warn simultaneously; even the situation of electric leakage also can be detected when safety electric flow sets up an organization in the normal range (NR) that arranges like this, be convenient to the timely eliminating of equipment fault.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises chip 1, safety electric flow sets up an organization 2, dropout drive system 3, dropout driving element 4, tripping actuating mechanism 5, display unit 6 and early-warning lamp 7, chip 1 respectively early-warning lamp 7, display unit 6 and safety electric flow sets up an organization 2 connections, safety electric flow sets up an organization and 2 to be connected with one end of dropout drive system 3, the other end of dropout drive system 3 is connected with one end of dropout driving element 4, and the other end of dropout driving element 4 is connected with tripping actuating mechanism 5.
When this embodiment uses: chip 1 is connected with instrument transformer a, the current signal that instrument transformer a gathers is sent to chip 1 by signal amplifier, processed by chip 1 and the concrete magnitude of current gathered directly is shown by display unit 6, early-warning lamp 7 can send warning light warning simultaneously, even the situation of electric leakage also can be detected when safety electric flow sets up an organization in the normal range (NR) that arranges like this, be convenient to fix a breakdown in time.When the magnitude of current exceedes safety electric flow normal range (NR), chip 1 sends signal by dropout drive system 3, and dropout driving element 4 drives tripping actuating mechanism 5 to carry out power-off.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
