Description

Terminal of shunt release with relay built in molded case circuit breaker

Technical Field

The utility model belongs to the technical field of the integrated technique of fire control type shunt release and specifically relates to a terminal of built-in relay type shunt release of moulded case circuit breaker.

Background

The shunt release is an accessory for remotely controlling the opening brake. When the power supply voltage is equal to any voltage between 70% and 110% of the rated control power supply voltage, the circuit breaker can be reliably disconnected. The shunt release is a short-time working system, the energizing time of the coil generally cannot exceed 1S, otherwise the coil can be blown. The plastic shell circuit breaker is characterized in that a microswitch is connected in series with the shunt release for preventing the coil from being burnt, when the shunt release is attracted by the armature, the microswitch is switched from a closed state to an open state, and because a control circuit of a power supply of the shunt release is cut off, even if a button is manually pressed, the shunt coil is not electrified any more all the time, so that the coil burning loss is avoided. When the breaker is buckled and closed again, the micro switch returns to the closed position again. The practical situation is that due to insufficient fire protection capacity, the fire protection power supply voltage is DC24V, 3A current is needed in a short moment, but the fire protection module is usually low in capacity and cannot be driven to work. In real-world operation, low-voltage users usually use the shunt coil of AC220V to control the shunt coil through the relay of DC24VHH52-54P, which requires external wiring, and the wiring is relatively complicated. Oftentimes fire fighting requires a passive feedback signal to indicate that the user is typically directly on the relay of HH 52-54P.

For example, the shunt release terminal of the molded case circuit breaker disclosed (announced) as CN204424186U is integrated with the shunt release coil of AC220V/AC380V, the control relay of DC24V and the feedback signal relay, so as to realize the integration of external wiring inside the terminal, optimize the appearance of the product and make the installation and use more convenient.

Because the conventional shunt release AC220V/AC380V needs to be matched with one DC24V, the terminal of the shunt release can be directly clamped on a molded case circuit breaker, and the DC24V relay needs to be installed on a split fixed guide rail, because the DC24V wiring screw is small, the point positions are more, and the wiring point on the relay needs to be led to an independent terminal by a wire for wiring a user in the complete set installation.

And the utility model discloses a this problem has been solved to the terminal, and relay module hides in the terminal, can directly block at the circuit breaker side, need not fix in addition. Set up 8 screw feet on the product, the size is big, and the outer end shell has the function wiring sticker convenience of customers to use.
