Abstract

A capacitor protector comprises an electric quantity protecting device. The electric quantity protecting device comprises a control module and a trip gear, at least one temperature sensor is arranged at a capacitor, detects the temperature of the position of the capacitor and converts the temperature value into temperature electric signals, at least one smoke sensor is disposed at the capacitor, detects smoke at the position of the capacitor and converts smoke value into smoke electric signals, the temperature sensor and the smoke sensor are both connected onto the control module, and the control module receives the temperature electric signals and the smoke electric signals and judges whether trip signals are outputted to control actions of the trip gear or not according to preset trip conditions. The capacitor protector is combined with the traditional electric quantity protecting device, guarantees reliable trip when the capacitor catches fire, reduces fault hazards, and removes the faulted capacitor in time.

Description

A kind of capacitor protection device

Technical field

The utility model relates to capacitor protection technical field in the electric power system, specifically is a kind of capacitor protection device.

Background technology

Capacitor in running, reasons such as, harmonic effects bad, fault such as catch fire easily owing to manufacture craft.When capacitor caught fire, the protection of traditional employing electric parameters protection philosophy can't reflect sometimes, because this moment, the fault amount did not reach the definite value that protection requires, causes fault can't excise for a long time, brings serious threat for the operation of normal device.

The utility model content

In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of capacitor protection device, and it guarantees can reliably trip when capacitor catches fire.Reduce the harm of fault, in time excised the fault capacitor.

For addressing the above problem, the utility model by the following technical solutions: this capacitor protection device comprises the electric parameters protective device, and described electric parameters protective device comprises control module, tripgear;

At the capacitor place at least one temperature sensor is set, detects the temperature at capacitor place and be converted to temperature signal;

At least one flue gas transducer is set at the capacitor place; Detect the flue gas at capacitor place and be converted to the flue gas signal of telecommunication;

Described temperature sensor, flue gas transducer all are connected on the described control module, control module receives described temperature signal, the flue gas signal of telecommunication, and judges whether to export trip signal according to its default trip condition and control described tripgear action.

The beneficial effects of the utility model are: increase flue gas transducer and temperature sensor near capacitor, combine with traditional electric parameters protective device, guarantee can reliably trip when capacitor catches fire.Reduce the harm of fault, in time excised the fault capacitor.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the structured flowchart of the utility model embodiment.

Embodiment

As shown in Figure 1, this capacitor protection device comprises the electric parameters protective device, and described electric parameters protective device comprises control module, tripgear;

At the capacitor place at least one temperature sensor is set, detects the temperature at capacitor place and be converted to temperature signal;

At least one flue gas transducer is set at the capacitor place; Detect the flue gas at capacitor place and be converted to the flue gas signal of telecommunication;

Described temperature sensor, flue gas transducer all are connected on the described control module, control module receives described temperature signal, the flue gas signal of telecommunication, and judges whether to export trip signal according to its default trip condition and control described tripgear action.

All the other do not state technology is prior art.
